What is laser hair removal?

Laser hair removal uses concentrated light energy to slow and reduce hair growth on your body and face.

Since the first laser created by Theodore Maiman in 1960, we’ve found many applications for them. But it was in the 1970s scientists discovered lasers worked to remove hair. That’s because researchers noticed hair loss as a side effect in other dermatological studies.

It perked the interest of the beauty industry who knew clients would pay for long-lasting hair removal. So, they funded research to develop machines and, around 20 years ago in the 1990s, laser hair removal finally became available to the public.

Since then, hundreds of clinical studies led to improvements in patient safety, comfort and results. Professional treatments are readily available in high-street cosmetic clinics and day medi-spas, as well as in dermatologist offices. It’s one of the most popular cosmetic treatments and consequently is BIG business.

At a clinic, you’ll need a course of 6 to 8 treatments, spaced at 4 to 6 weeks apart. Costs range depending on the clinic and the body area(s) treated.

What is IPL hair removal?

IPL stands for Intense Pulsed Light. It’s not a laser, but it too uses light energy to slow and reduce hair growth on your body and face.

The first clinical studies of IPL in 1976 were for treatments of vascular legions. Loads more studies more followed into various applications including hair removal. As with lasers for hair removal, the opportunities proved attractive potentially lucrative, and the first reported clinical study of a commercial IPL machine dates to 1997.

IPL proved as popular as laser hair removal and many clinical studies led to improvements in technology, safety, comfort and results. It’s available on the high street for cost effective long-term professional hair removal.

The treatment protocol matches laser hair removal with 6 to 8 treatments at 4 to 6-week intervals. Costs tend to be cheaper than laser hair removal, and practised more widely in beauty spas versus doctor-led cosmetic clinics.

Just like professional treatments, home laser and IPL hair removal uses concentrated light energy to slow and reduce hair growth on your body and face. The machines are much smaller and less powerful than professional machines. And with much simpler controls so that you can use them safely in your own home.

All the home machines reviewed on this site are clinically tested and proven effective for long term hair reduction and safe use at home. They range in price and features.

Many are from trusted household brands such as Philips, Panasonic, Braun and Remington. Others are specialists in home beauty and hair removal devices such as Smoothskin, Silk’n and Tria.

Next, let’s look at how they work.

How does laser hair removal work?

You can learn in depth how lasers work here. But what’s relevant to us is that a laser is a monochromatic focused beam of light energy. Monochromatic means it’s of just one wavelength, or colour.

An illustration of a cross section of human skin with a red laser energy beam focused on a dark hair follicle for laser hair removal.
A laser for hair removal is of a single wavelength which penetrates deeply into the skin. Hair removal lasers with different wavelengths are absorbed by melanin.

We measure wavelengths in nanometers (nm). Now, different substances in our body absorb specific light wavelengths. We call these substances chromophores. Chromophores are the dark pigment in hair (melanin), oxyhaemoglobin in blood, and water.

For laser hair removal we care about melanin in our hair. Melanin absorbs wavelengths between 600-1100 nm. So, there are different types of professional laser capable of hair removal. For example:

  • Ruby laser (694nm)
  • Alexandrite laser (755nm)
  • Diode laser (800nm)
  • Neodymium-doped:yttrium aluminium garnet laser (Nd:YAG) (1064nm)

The cells with melanin in your hair follicle absorb the laser pulses. This converts to heat which damages the hair follicle. The hair then shuts down and enters a resting phase. So, you see slower growth and eventually, many fewer hairs growing; this is hair reduction.

How does IPL hair removal work?

IPL uses a xenon flashlamp giving bursts of diffuse, non-coherent light. This means it’s made of many different wavelengths or colours and can’t focus as a laser can. The wavelengths for IPL are 500 to 1200 nanometers.

An illustration of a cross section of human skin with multi colour/wavelength Intense Pulsed Light flashing it and absorbing in a dark hair follicle for IPL hair removal.
IPL for hair removal is of a several wavelengths absorbed by melanin. It travels through your skin and is absorbed by the hair at different depths in the follicle.

We know the chromophores in our body (melanin, haemoglobin and water) absorb different wavelengths. So, IPL filters cut-out unnecessary wavelengths to target a specific chromophore. To target melanin in hair reduction you filter all except wavelengths between 600 to 1100 nanometers.

TIP: IPL can therefore treat several different concerns. Applying different filters on the machines means the light energy also works to treat spider veins and pigmented cells such as sun-spots for facial photo rejuvenation.

So, the cells with melanin in your hair follicle absorb the multi-wavelength flashes of IPL. This converts to heat which damages the hair follicle. The hair then shuts down and enters a resting phase. So, you see slower growth and eventually, many fewer hairs growing; this is hair reduction.

That’s the simple answer of how laser and IPL hair removal work you’ll find most everywhere. If you want even more detail on this process called selective photothermolysis, what happens to the hair, and how you get long-term hair reduction, check out this:

Home devices safe skin tones

Safe skin tones and effective hair colours noted in a user manual

Home laser and IPL devices follow the same selective photothermolysis approach as professional machines to reduce hair growth. This means not all devices are safe for darker skin tones.

Laser and IPL hair removal gives best results on light skin and dark hair. That’s because the light energy heats-up dark melanin pigment in the hair follicle. There’s little melanin in light skin so the energy leaves it unharmed.

There’s much more melanin in darker skin. So, the IPL and laser energy heats this up too. Home use devices are much less intense than professional machines, but they can still cause skin damage and pain if the skin tone guidance isn’t followed. You can develop skin reactions, such as temporary or permanent skin darkening or lightening, strong redness, burns and blisters.

The Fitzpatrick skin types

Manufacturers use the Fitzpatrick skin type chart to clearly show which devices are safe for which skin tones. There are 6 Fitzpatrick types, measured from type I to VI. Type I is the lightest skin and type VI the darkest.

Skin Type Skin colour Tanning ability
Light, pale white skin Always burns in the sun and never tans
White, fair skin Usually burns in the sun and tans with difficulty
Medium white to olive skin Sometimes burns mildly in the sun and gradually tans
Olive to mid-brown skin Rarely burns in the sun and tans with ease to a moderate brown
Brown to dark brown skin Very rarely burns in the sun and tans very easily
Very dark brown to black skin Never burns in the sun and tans very easily


Light to medium skin types

Colour tone swatches for FitzPatrick types I to IV, light to medium skin tones.

If you have light to mid-brown skin (Fitzpatrick types I to IV) all home-use devices are safe for you. Check out the recommended best buys.

You can use any intensity level on lighter skin I to IV with the Tria 4X laser. And with IPL devices, you can safely use the higher intensity levels. The higher levels give longer-lasting results too.

Dark & black skin

Colour tone swatches for FitzPatrick types V to VI, dark and black skin tones.

A few home IPL devices have special filters and are safe for dark skin up to type V. And there’s one IPL safe for the darkest skin type VI too.

The Tria 4X laser is not safe for these skin darker skin tones. You must use lower IPL intensity levels too. Most machines have 5 levels. There’s sometimes a guide in the user manual as to which to use on specific tones. Most also have skin tone sensors to protect skin that’s too dark.

Each of our device reviews clearly shows the safe Fitzpatrick skin types in a skin tone chart at the start of the review.

Home laser & IPL for dark hair only

Just like professional treatments most home laser and most IPL hair removal are effective on dark hair only.

Hair colour swatches dark blonde, light brown, brown and black

Dark blonde, brown and black hair has a dark type of melanin called eumelanin. This is absorbed by the light energy resulting in effective hair reduction.

This image has an empty alt attribute; its file name is light-blonde-to-grey-hair-368x113.png

Light blonde hair has just a little eumelanin, usually not enough to absorb the light energy. Red hair has a different type of melanin called pheomelanin. Grey and white hair has no melanin at all. They won’t absorb the light energy.

Despite this, there are a few possible considerations from brands offering money back guarantees, or IPL combined with other energies.

Where can you use it?

At-home laser and IPL machines are safe to use on specific body areas only. And there’s different guidance for men and women too.


Common areas are the upper lip, chin, jawline, sideburns, armpits, forearms, tummy, bikini line / Brazilian, legs, feet and toes. From the very honest online reviews you can also add the neck, chest, around the nipples and bum.

Several ladies with hursutism and Polycystic Ovary Syndrome (PCOS), which cause male pattern hair growth, use IPL and home laser to successfully manage their excess facial and body hair to get their confidence back.

You can choose to treat just a few areas or go for smooth on your entire full body (from the cheekbones downwards, not around your eyes!).


The most common treatment areas for men are neck, shoulders, back, chest and torso. From the online reviews other men share they treat their legs, feet, hands, fingers, underarms and bikini / Brazilian too.

Home IPL and laser are not suitable for men on the face. And ALL manufacturers warn not to use it on men’s beards. However, I’ve found several male Youtube reviewers using IPL or laser on their beards with varying results. Some see slower and softer regrowth that’s easier to manage.

However, it’s a risk to use it there because it’s not clinically tested on male beards. Brands give different wanings. some say:

  • There’ll be limited results because of the thickness, density and depth of male beard hair.
  • Using it can cause pain
  • Leave unintended bald patches
  • Have little effect after prolonged use
  • Can cause adverse and unsightly reactions – not a good look on your face!

Instead, look at professional laser treatments for men because reputable clinics can safely treat most body areas, including your beard and face.

IMPORTANT: For both men and women home IPL and laser hair removal is NOT suitable:

❌ for use on the genitals, nipples and anus. Skin there is usually darker and so there’s a higher risk of burns and side effects.
❌ around the ears, around the eyes and on warts, moles or large freckles.

Is home laser & IPL hair removal safe?

Yes. Just like professional treatments there’s no link to cancer or infertility.

All of the devices we’ve reviewed and recommended are clinically proven safe for home use. They are designed with the following in common:

  • Much lower intensities than professional treatments
  • A selection of intensity levels caters to varying skin tones
5 intensity indicator lights illuminated blue on the Panasonic ES-WH90 home IPl hair removal device.
Most home laser and IPL hair removal devices have 5 intensity levels. High intensity is safe for light and low for darker skin tones.

They also have in-built safety features to keep you safe:

  • IPL devices have inbuilt UV filters to protect your skin
  • Skin sensors prevent accidental flashes protecting your eyes, so no need for eye protection
  • Skin tone sensor stops flashes on skin that’s too dark
  • Automated skin tone sensors to select your intensity level before every flash

But it’s still very important you follow the skin tone guidance and contraindications.

Skin tone sensors protect skin that’s too dark, and some such as the Smoothskin Muse (pictured) even detect your skin tone and select your best intensity before every flash.

Home laser & IPL hair removal contraindications

Just like professional treatments, you could be unsuitable to use a home-use device for several reasons. These reasons are called ‘contraindications’ and they range from pregnancy to medications making you more sensitive to light.

Close up photos of the contraindications listed in a home use IPL hair removal device user manual.
Check the user manual warnings and contraindications BEFORE you buy!

Here’s a quick summary. However, it’s not an exhaustive list so check with the brand and / or your doctor if you’re unsure. And check the user manual before you buy a device. Visit the websites or email customer support if you can’t find it.

Before you buy a home use device, check:

  • You match the safe skin tones & dark hair colours
  • You’re not pregnant, trying to get pregnant or breastfeeding
  • You’ve not recently sun tanned or used tanning creams
  • You’re an adult. Some brands say over 16 and others over 18

In your treatment areas, don’t use it on:

  • Nipples, genitals or around the anus
  • Ears or around eyes / eyebrows
  • Male beard
  • Dark brown or black spots such as birthmarks, moles or warts
  • Varicose veins
  • Damaged skin e.g. sunburns, cuts, open wounds or active infections, cold sores etc
  • Tattoos or permanent make-up
  • Active implants such as pacemaker, neurostimulator, insulin pump or over silicone implants
  • Areas you use long-lasting deodorants

Don’t use it if you have a medical history of:

  • Conditions such as diabetes, congestive heart disease, history of keloid scars or poor wound healing, epilepsy with flashlight sensitivity, bleeding disorder, immunosuppressive disease including HIV or AIDS
  • Sensitivity to light
  • History of skin cancer or pre-cancerous lesions
  • Radiation therapy or chemotherapy in the past 3 months
  • Surgery in treatment area in the last 3 weeks
  • Chronic skin disease e.g. psoriasis or vitiligo
  • A skin peel (within different time frames given)

Don’t use if you’re taking or have recently taken these medications:

  • Painkillers, which reduce sensitivity to heat
  • Immunosuppressive medications
  • Anticoagulation medications
  • Medications which make you sensitive to light e.g. Retin A, isotretinoin Accutane or other topical retinoids

Always check your medication instruction leaflet to see if photosensitivity is a listed side effect.

Side effects of home laser & IPL hair removal

As with professional treatments, there are some very rare side effects with home use laser & IPL devices. These generally occur when the intensity is too high for your skin. You should wait until your skin heals and returns to normal before doing another session at a lower intensity.

Close up photo of a home use device user manual at the possible side effects section.
Check the possible side effects listed in the user manual.

Here’s a list of possible but rare side effects. If they don’t fade within the times detailed below, go see a doctor.

  1. Burns, excessive redness and swelling around your hair follicles, should disappear within 3 days
  2. Lighter or darker skin patches, should disappear within 2 weeks
  3. Epidermal heating is a sharply defined brownish area that’s NOT dry, and it’s most common with darker skin tones. It should disappear within 1 week
  4. Blistering, small bubbles on the surface of the skin,. They should disappear within 1 month
  5. Skin infection can occur, especially after a burn or skin irritation
  6. Scarring, usually following a burn that takes longer than 1 month to heal
  7. Folliculitis is swelling and pustules around your hair follicles caused by bacteria in damaged skin. Go see your doctor immediately for treatment.

The Tria 4X user manual also lists increased hair growth after the first session. as a side effect. If it continues after several sessions go see your doctor.

You can choose devices with top safety features to reduce the risk of side effects. The super-safe Braun Pro 5 IPL and the Smoothskin Muse have advanced skin tone sensors which select the best, safest intensity for your skin before every flash.

Or you can choose gentler, lower intensity devices such as the Smoothskin Bare and Silk’n Infinity. These are also safe for darker skin tones but still work on fair tones. They’re worth considering if you’re very concerned about side effects or a bit apprehensive about it all.

As with professional treatments, you increase the risk of these side effects if you expose your skin to the sun before or after your sessions. So follow the tanning guidance!

Tanning guidance

Do you tan regularly?

If you sunbathe regularly, or spend a lot of time in the outdoors you must take care of your skin whilst using home devices.

IPL / laser hair removal and tanning don’t mix for two big reasons.

  1. Safety: The combination increases your risk of skin reactions
  2. Effect: Tanning darkens your skin so you’ll need to user a lower power intensity level. The higher levels are most effective.

To protect your skin and keep you safe, the device manufacturers provide warnings and guidelines around fake tanning, sunbathing and sun exposure. Check them in the user manuals before you buy.

So, what are the guidelines?

Before your treatments

Close up photo of the tanning guidelines section in the Lumea Prestige user manual.
Check the user manuals for guidance on tanning and sun exposure

Manufacturers give different guidelines for how long you must avoid the sun before your treatments. It varies from a cautious 4 weeks, a more manageable 7 days and a short 48 hours. All advise you perform a new patch test afterwards. This checks your skin’s sensitivity and also if you need a lower intensity level to match your tan.

Here’s why: Whether you tan easily or slowly, natural and artificial sunlight increases the melanin in everyone’s skin.  If you use IPL after sunbathing or sun exposure, you’ve got a high risk of reactions and damage to your skin. Damage such as burns, blisters and temporary and permanent skin darkening (hyperpigmentation) or lightening (hypopigmentation) or scarring.

After your treatments

Post-treatment sun exposure guidelines vary too. The most cautious says avoid the sun altogether for 2 weeks after your treatments. Another recommends at least 7 days. And just one suggests 48 hours. All say to use a minimum SPF 30+ in the sun for around 2 weeks after your treatment.

Here’s why: laser and IPL makes your skin extra sensitive so it’s at more risk than usual from sunburn and side effects after your treatments.

Tanning with creams

Manufacturers say to wait for the artificial tan to disappear completely before treating your skin.

Should you avoid tanning altogether?

Yes. The majority of guidelines mean it’s safer and more effective to complete the start-up stage before you start working on your tan (both natural or artificial).

Without a tan you:

  • Can use the highest energy intensity level suitable for your skin type, and so get best results
  • Don’t increase the risk of sunburn after a treatment
  • Don’t increase the risk of post-treatment skin reactions
  • Get the best results from your treatment regimen

Complete your treatments in Autumn or Winter months, or if you can’t avoid the sun cover up and use minimum SPF30 sun lotions. It’s best to stop using fake tan lotions too.

Once you’ve completed your start-up phase, it’s easier to plan occasional top-up treatments safely around sun exposure and tanning.

For some, these guidelines are impractical or the need to tan outweighs the need to banish hairy areas! You must decide if it’s right for you. Or you risk your machine gathering dust in the bottom of a draw.

— How to prepare & what to expect —

In this section:

Read the user manual

It’s very important you read the user manual thoroughly.

TIP: Read it before you even buy a device. Head over to the brand website – most have a downloadable copy. If they don’t, email customer support and ask for the latest version.

Photo of the Tria 4X user manual
Read the user manual before you buy and before you start treatments

Reading it helps you understand how to use the device for best results, lists the contraindications or reasons you’re not suitable to use it, warnings and precautions, explains the treatment schedule, what to expect and gives a troubleshooting guide.

N.B. Some devices come with a shorter quick start guide. This is a handy reminder for your subsequent treatments. It’s not a substitute for the full user manual which has much more comprehensive information.

Do a patch test

With most devices you must do a patch test. Shave a spot in your treatment area and zap it according to the instructions in the user manual.

This confirms it’s safe for your skin, and you won’t have any side effects. With some devices you must test a few different intensity levels to find your ideal one. With other devices they choose the best intensity level for you. Wait the recommended time (usually 24 hours) and check your skin. If you’ve still any reaction, you should either test again at a lower intensity or talk to your doctor.

If you haven’t used the device in a while, especially after Summer if you’ve tanned, it’s wise to do another patch test.

For best results shave

Photo of a lady shaving here legs over the bath.
For best results, shave before your home laser or IPL sessions.

Shaving immediately before each session gives you your best results from home IPL and laser.

TIP: Hair conditioner works brilliantly on legs, underarms, and bikini line instead of expensive shaving gels!

Hang on though. Do you have to shave your face?

Shaving your face is just too darn masculine! Yup. I agree. Now, most brands suggest instead you trim your facial hair with scissors. But I think a dermaplaning tool is a much better solution.

Hollywood Browzer dermaplaning tool in black, a much better alternative to shaving your face!
Hollywood Browzer dermaplaning tool to remove facila hairs without irritation!

Use them on your upper lip, chin, jawline, sideburns, cheeks and even for an eyebrow tidy-up! Simply stroke them along your dry skin at a 45°angle. The sharp, safe blade removes thick hairs, soft peach-fuzz and exfoliates the dead, dry outer layer of skin. You don’t need shaving foam, gel, oil or water. And your hairs won’t grow back thicker or darker either.

Before each session, make sure you’ve had a close shave and there’s no hair left on the skin surface. If there is, it stings and burns with each flash! Also, ❌ don’t apply any moisturisers or deodorant to your skin as this could cause unwanted reactions with the light energy!

Shave before every subsequent treatment. And you can also shave in between sessions as you need. It becomes much faster and easier as your hairs soften, so stubble isn’t a concern for long. Then bald patches appear until eventually there’s no hair to shave away! Before your sessions or top-ups, simply check your skin for any stray hairs and shave/dermaplane them if you need to.

TIP: DON’T use hair removal creams because they may cause skin reactions with the IPL.

A few brands say you can wax, epilate or pluck your hairs before a session. However, the IPL and laser won’t be quite as effective versus shaving.

Related: Learn more about dermaplaning, and shaving vs waxing/plucking in this article here.

Get set up

Next, choose a comfortable spot to do your treatment. Depending on which body areas you’re treating, privacy is a good idea too.

Photo of a lady looking in a mirror as she zaps her upper lip with the cordless Lumea Prestige.
A mirror helps with your face, underarms, bikini line and backs of legs, bum etc…

You may want to set up in the living room and watch TV. Or in your bedroom. Here are a few tips to get started.

  • In front of a mirror: A full-length mirror is very helpful for a thorough bikini line, underarms and backs of legs
  • A mains extension cable: Most devices have a long power cord, but maybe not long enough if you want to sit on your bed. So, an extension cable from the mains gives you more.
  • Find privacy: Zapping your bikini line or bum lacks elegance and it’s not something you’ll want to share with housemates, kids, window cleaner etc. Try to find privacy in your bedroom or bathroom.
  • Choose the right time: It takes time and concentration to get good results. So, stop any interruptions. Choose a time when kids are tucked up in bed.         

Next, what to expect during your treatments, then after your treatments and your hair reduction results.

What does IPL feel like?

You’ll hear the cooling fan whirring and a soft ‘pop’ with each IPL flash.

The IPL flashes are bright, but harmless to your eyes. You don’t need to buy specialist goggles or glasses. Use it in a well let room so the flashes don’t seem so intense. Some people find it gets tiresome after a while and wear sunglasses to ease the irritation.

You may smell some singed hair too.

Does home IPL hurt?

The flashes mostly feel warm against your skin. But some areas, like ankles, thighs, bikini line and underarms can smart more because they’re more sensitive. Most brands liken this sensation to an elastic band snapping against the skin. It’s instantaneous, uncomfortable but bearable.

You may also feel increased heat on your bikini line and underarms where your hair is generally thicker and denser. From the online feedback, users with darker skin tones report it hurts most frequently. It can depend on your hair density and skin sensitivity. In any of these cases, drop the intensity level a notch or two if it’s too much.

Try starting with your face and more sensitive areas when the flash window area is cool. It also takes a bit of concentration so you don’t miss any areas.

IMPORTANT: You can feel pain if your skin isn’t hair free, if the light’s too intense for your skin, if you flash the same area more than once, or if you flash an open wound, infection, tattoo etc.

What does laser feel like?

Tria 4X home use laser hair removal

There’s one home-use Diode laser hair remover.

You’ll hear the whirring cooling fan. It communicates with a series of beeps and buzzes. Beeps confirm when something is done and a buzz means bad skin contact and you need to zap that bit again.

You may smell burning hair too.

You won’t see any flashes or light from the Tria 4X at all.

It takes lots of concentration. That’s because the zap area is so small and you need to get just the right amount of overlap. You can work in roughly 30 minutes sessions until the battery charge runs out.

Does home laser hair removal hurt?

Based on the negative and positive user feedback there are more reports of pain with the Tria then with other IPL devices.

Again, Tria use the elastic band-snapping analogy. For some this is true, but for others it’s a much more intense, hot and sharp sensation.

The Tria laser light is the most powerful home-use device. All intensity levels are safe for Fitzpatrick types I to IV. A clinical study suggests the higher levels are 2 to 3 times better than the lower ones. And on the highest level the power is 20 joules per cm2.

This energy reaches deep down to the hair follicle and the melanin in your hair absorbs it. This causes more heat than with IPL. Therefore, there’s more damage to the hair follicle, but for some people it’s accompanied by pain. It depends on the individual.

Some users try the Tria Smooth start gel, lidocaine gel or just an ice pack to numb their skin. You can also reduce the intensity level. After a few sessions painful sensations mostly reduce too.

So, what should you expect after your treatments?

Common skin reactions

Skin redness is a common reaction to IPL and laser. Your skin may also feel a bit hot and tingly. It could feel dry and itch a bit too. That’s likely due to the combination of shaving and light.

It’s all normal and should wear off within 24 hours. You can cover it with a cool face cloth or ice pack. Cooling water sprays are good too, Aloe Vera gel or a non-scented moisturiser.

If you have no reaction at all, you can apply your usual cosmetics, moisturisers and deodorants. If your skin becomes irritated afterwards, wash off any products you applied.

After your treatment, avoid things that could irritate the skin you’ve flashed. For example, using hot tubs and saunas, wearing tight-fitting clothing, using bleaching creams and perfumed or exfoliation products.

Avoid the sun and wear an SPF 30+ on areas exposed for prolonged periods. If you don’t you risk experiencing some of the rare home IPL and laser side effects.

How long do home results last?

First up, let’s see what the recommended treatment schedules look like, then what results most people see and when.

Treatment schedule

Each brand recommends a start-up phase. This schedule is usually the same regimen followed in the clinical tests.

Close up photo of the treatment schedule diagram on the Philips Lumea Prestige box, showing x5 sessions over 8 weeks then the first touch-up session at week 12 and the next at week 20.
The start-up and touch-up treatment schedule diagram shown on the Lumea Prestige box.

The start-up phases are between 4 to 12 sessions. Some you must do weekly and others every 2 weeks. You keep up with these regular sessions until your skin is smooth. Then you do less regular top-up sessions to stay smooth. Most need these at 1- or 2-month intervals.

Here’s a quick summary by brand:

Brand Start-up sessions Frequency Suggested Top-ups
Philips (all models) 4 or 5 Every 2 weeks Every 4 to 8 weeks
Tria 4X Up to 8 Every 2 weeks As needed
Smoothskin Muse Up to 12 Weekly Every 4 to 8 weeks
Smoothskin Bare Until smooth Weekly Every 2 or 3 weeks
Braun silk Expert 5 / Pro 5 IPL Up to 12 Weekly Every 4 to 8 weeks
Silk’n Infinity 1 to 4
5 to 7
Every 2 weeks
Every 4 weeks
As needed
Remington 1 to 3
4 up to 12
Every 2 weeks

Top-ups are just as important

So, with all brands there’s similar upfront commitment and investment in effort and time. But what’s important (and often not made clear) is the top-ups are very important too.

A recent long-term study of home IPL devices found that the top-up sessions continue to work on your hair follicles. The effect deepens so the more you do the longer your hair-free results last.

The study showed that if you stop at 4 sessions hair grows back. But if you continue for 1 year with less frequent sessions (every 6 weeks) you’ll achieve high hair reduction lasting for at least 1 year after stopping the sessions.

New hair growth is still possible. That’s because dormant hair follicles can activate and grow new hair. So, hang onto your razor! You can shave and do just very occasional top-ups as you see any new growth.

These are the typical results which most people experience. However, results do vary by individual and all brands say this on their websites and in the user manuals (yes, even Tria). So, what does this mean?

Results vary

There are a few things affecting your hair reduction results. They are:

  • Your skin and hair colour combination (results generally take longer on light hair and / or dark skin)
  • Hair thickness
  • Your genetics
  • Hormones, and conditions like hirsutism (excessive hair growth) and PCOS
  • How thoroughly you cover your skin
  • The number of sessions / top-ups completed

‘Varied results’ mean you may get a lower hair reduction (amount and thickness of hair) than promoted by the home brands. The results may not last as long either so you could need more regular sessions to maintain your results.

A small number of online feedback from all devices matches this too. Whilst a few are very disappointed they don’t see the advertised results, many others are still happy. That’s because they’re able to maintain longer-lasting results with much less time and effort than before. A regular session every few weeks sure beats painful daily plucking or shaving, or the expense of waxing sessions. For them the results still feel life-changing.

TIP: From online reviews, several people with PCOS use home IPL and laser as an affordable way to manage persistent and visible facial hair. It proves much more effective than plucking and waxing, giving their confidence back.

So, what are other results from user reviews of home IPL and laser hair removal machines?

User feedback hair reduction results

Smooth, soft, hairless skin. Lovely.

From the user reviews, there’s a small number who, despite being excellent candidates, don’t get the results they want. Others are disappointed because they stop using it and the hair eventually grows back.

But most experience results that match the start-up phases. It goes like this:

  • After 1 or 2 sessions you’ll still see hair growth. And hair doesn’t fall out immediately. Shave before your next session.
  • After 2 to 4 sessions you should see less hair and smooth patches. Your hair is also finer and lighter, and easier to shave.
  • After 3 to 6 sessions you should have large bald spots, very fine and light regrowth or even be totally smooth! You may not need to shave between sessions.
  • After that continue as directed by the user manual either to complete the full regimen or start your maintenance phase with top-ups every 4 to 8 weeks.

Some users experience very fast results, whereas others needed 2 or 3 times as long. It varies by individual. So, if you don’t see results within a few goes, don’t give up! Stick at it and give it more time.

Totally smooth?

It’s also important to note that some never get to totally smooth. What they get is very slow, fine and light regrowth. They can go from shaving daily to every week or month.

Some also need top-up sessions more frequently than every 4 weeks. However, they’re happy because it’s much easier to shave and they do it so much less frequently. Overall, they spend much less time and effort to feel silky smooth.

Some long-term reviews share the longer they’ve done their top-ups the less frequently they need them. Some only do a couple every year, or as they see new hairs growing. This is my experience also, and shows results are very long-lasting after several frequent top-ups.

Other reported effects

Other happy effects are no more shaving rash or bumps because hair’s so much softer and finer. Skin feels soft, smooth and healthy.

The black dots associated with hair growth disappear. And pores seem to shrink too.

No more scratchy armpit or bikini line stubble either. And loads love that itchy and unsightly ingrown hairs quickly disappear!

I love being able to wear what I want, when I want. Shorts, skirt, summer dresses, bikini. I’m ready for it all.
