Silk’n Flash & Go Express review (300,000 flashes)

Silkn Flash&Go Express Laura G
Silkn Flash&Go Express

4.1

The Flash&Go Express is the most advanced model from Silk’n that’s available in the US. It costs $100 more than the Flash&Go Compact but it’s still at a very competitive price. It’s super value when compared to other brands because you get a lot for your money. It’s a smart investment with over 15 years’ worth of full body treatments. That’s probably more than you’ll ever use. And it’s designed to give you fast treatments too, one of the fastest from this type of compact model. It’s one of the best no-frills choices out there and the user reviews love it too. So keep reading to see if you will too.

Suitable skin tones and hair colours

Silk’n don’t use the Fitzpatrick scale to confirm safe skin types and tones. For this reason I can’t confidently say it’s a good choice for darker skin tones. The user manual says use it on all hair colours too. But it also says it may not be as effective on naturally white, grey, blond and red body hair. So I think it’s safer to reflect the simple guide on Silkn.com that says the Flash&Go Express is “best suited for lighter skin tones and darker hair”.

skin-tone-hair-colour-chartYou can use it on black, dark brown, brown, dark blonde hair and light to medium dark skin tones (Fitzpatrick skin types I to V).

You can’t use it on light blonde, red, grey or white hair and brownish black and darker skin tones (Fitzpatrick skin type VI), or on freckles and moles.

Tanning guidelines

Silk’n advise don’t use the Flash&Go Express on tanned skin or after recent sun exposure. Avoid sun exposure for 4 weeks before your Flash&Go treatment. If you’ll be in the sun protect recently treated skin with sunscreen (minimum SPF 30). Do this for 2 weeks after each hair removal session.

In this full Flash&Go Express review:

Is the Flash&Go Express good value?

 Bar chart showing the Silk'n Flash&Go is great value and takes 5th spot.

The Silk’n Flash&Go Express provides superb value for money with plenty treatments. 300,000 flashes combined with the 2.7 cm2 body treatment window means you can treat a total body area of 810,000 cm2, or 2000 full body applications for 15 years of use.

Yes. With the 2.7 cm² treatment window and 300,000 flashes you can cover a maximum treatment area of 810,000 cm². That’s enough for about 200 full body treatments (full legs, bikini line, underarms and face). After the start-up phase this will last about 15 years of monthly top-up treatments!

That’s plenty of treatments, more than you’ll ever need. That’s why Silk’n.com actually say it “provides a LIFETIME of hair removal with permanent results for 2 USERS…” so if you share the device for full body treatments you can expect over 5 years of top-up treatments each.

N.B. I’ve used only the bulb life to calculate the years of use. General usage and wear and tear can also affect how long the machine keeps working.

What’s it like to use the Flash&Go Express?

It arrives in a neat, rich-blue box with a white slide-off sleeve that has all the key information printed on it.

The Express device and the power pack are nestled within a sturdy, grey zip-up storage case. It’s a great choice if you want something compact and portable.

“It’s lightweight but doesn’t feel cheap and is fairly easy to work with and was very quick and easy to use as well.”
Influenster reviewer

The hand-held device is compact with a simple design and shape. It’s white with a bold blue block of colour. It’s no-frills, so don’t expect a fancy ergonomic grip, metallic trim and other refinements.

Whilst compact in size, it’s still robust and comfortable to hold. The power cord looks long enough and it fits securely in the base of the device.

What’s in the box?

  • Express Hair Removal Device
  • Deluxe Carrying Case
  • Cleaning cloth
  • Power Cord
  • European, Asian, North American plug adaptors
  • User Manual

Let’s start with the user manual.

Read the user manual

To understand how everything works, start with the user manual. It tells you how to be safe and get best results. Pay close attention to the list of warnings and safety precautions to see if you should not use the device.

The manual is comprehensive and plainly sets out the risks and possible side effects. It does a good job of explaining how to use it, and what to expect when you use from sounds to sensations. Some suggest that video tutorials would be helpful too. And I’d like to see the user manual explain how or if Silk’n HPL technology is different to other home intense pulsed light devices. But it doesn’t.

The user manual doesn’t suggest you do a skin sensitivity test and this is a bit odd. Read on to learn why.

Choosing your intensity level

Compact blue box with white information sleeve

Try following the UK user manual instructions for a skin sensitivity test. You can progress quickly to the optimum intensity level for your skin and get the best results possible.

The manual says do your first treatment on the lowest intensity setting. If it’s comfortable and you have no reactions then move up a level for the next session.

The manual also warns “Do not raise the energy level during a hair removal session even if you experience no discomfort. Discomfort may also appear sometime after the session.” I have 2 concerns over this.

  1. There’s no direction to perform a skin sensitivity test.
  2. It will take you 5 treatments / over 6 weeks to reach the highest intensity level (if it’s suitable for you). Because the device is most effective on the higher levels this will slow down your results. The advertised and expected results will take longer to see. A few reviewers also share this feedback.

I think the solution is a skin sensitivity test, so you can follow the guidelines from the UK Silk’n Glide user manual, as follows:

“For the skin test, shave first then after checking your skin with the skin tone sensor, simply start at the lowest level (1) and flash your skin. If that’s comfortable move up a level and repeat (on a different spot). Stop if it becomes uncomfortable or painful. Wait for 1 hour and if there’s no reaction continue with your treatment at the highest level that was comfortable. Do this for each body area you want to treat.”
UK Silk’n Glide user manual

 I also found that theSilkn.com FAQ section says “Progress quickly to high energy levels – once you have tested all treatment areas on the low energy setting, we recommend you move up to higher levels.” I suspect this direction was missed from the user manual.  If you’re unsure what to do, please check with Silk’n customer support.

Getting started

Please be safe: Before using always read the user manual.

It’s very easy to get started and as most reviewers comment it’s super-simple and fast to use!

  1. Shave and make sure your skin is clean, dry and free of lotions and deodorant.
  2. Set yourself up. You’ll need to be near a power socket. Try using an extension cable so you can choose the most comfortable area, like your bed, or close by to a mirror.
  3. Plug it in and simply press the power button to move up the levels and the indicator lights around the button show the selected level.
  4. A ‘ready’ light will blink when it’s in full contact with your skin.
  5. Press the flash button and the skin tone sensor checks your skin tone. It’ll flash only if it reads a suitable tone. When it flashes you’ll hear a ‘pop’ sound.

The flashes are bright, so don’t look directly at them. Make sure you use it in a well-lit room, but avoid vanity mirrors that can cast shadows across your skin. Try wearing sunglasses if the flashes are too much.

Skin tone sensor & safety

The small rectangular skin tone sensor window sits below the main, recessed flash window.

The skin tone sensor means you can’t use the Silk’n Flash&Go Express on darker skin and the skin contact sensors around the flash window must be completely covered before it will flash.

Your skin tone is checked by the small safety sensor window next to the light exit window. It checks at the start of your treatment and periodically throughout your session. It won’t flash if your skin tone is out of the safe range.

Sensors around the window make sure it’s is fully covered by your skin before it will flash. This means you can’t accidentally flash into open air and damage your eyes.

Treatment modes

“This device was super easy to use, lightweight, and totally pain free!”
Influenster reviewer

The Flash&Go Express has 2 standard treatment modes of stamping for a single flash (called Pulse) or continuous flashes (called Gliding).

Use Pulse mode to cover small areas and uneven surfaces. Place the device on your skin, press and release the flash button. Then position on the next spot and repeat. It leaves gentle pressure marks on your skin providing guide marks for where to position it next.

Gliding makes it more comfortable to hold when treating larger areas like your legs.  Position the device on your skin and press and hold the flash button. Then, keeping good contact, slide it over your skin a small space at a time. Try to move it just the height of the flash window, to get good coverage in time with the flashes.

How quick are the treatments?

Large flash button on the side of the device

Press and hold the flash button and slide the window over your skin to treat large areas like legs quickly and in comfort. One leg takes from around 8 minutes.

So you can compare it, let’s see how long it takes to treat a pair of underarms.

The Flash&Go Express has a 2.7 cm² treatment window and it flashes once every 1 or 2 seconds dependent on the intensity level used. So, to treat a pair of underarms (an area roughly 120 cm²) it’ll take from around 44 seconds up to 1:29 minutes. It’s quick!

Silk’n.com say the Flash&Go Express “reduces treatment times by up to 50%” vs the Flash&Go Compact model. That model takes around 16 mins per leg, so you’re looking at from 8 mins per leg here. That’s good and makes the Flash&Go a good choice for full body treatments and large areas treated in one session.

A few reviewers comment it takes longer than 20 mins to complete a full body treatment, which suggests at some point Silk’n said this was possible. However, some say they are done in under 30 minutes which is still pretty fast work.

Tricky bits and helpful tips

  • There’s no smaller treatment window for small and uneven areas. So takes a bit of fiddling to activate a flash on areas like shins, knees and ankles.
  • It’s awkward to position on the upper lip – try blowing out your cheeks or suck in your lips to create a flat surface.
  • A few reviewers have trouble where the Flash&Go Express won’t flash and it takes some time and effort to get it right – make sure the’re no shadows cast on your skin, and that you’re covering the skin tone sensor and skin contact sensors properly.

Excellent customer support

Silk’n give an extended 2 year warranty if you buy through Silkn.com. Their customer support is great too.

To get in touch you can call, use an online form or online chat. The team are prompt and thorough and offer helpful advice. You feel you’re in safe hands if you have any problems or need advice.

What do online reviews say?

From all the collated online Flash&Go Express reviews, it scores a very good 4.1 stars.

User score 4.1 stars

Let’s start with the lower-rated reviews – what do they say?

The bad bits

A handful of low ratings come from users who find it difficult to get the device to flash. It’s not clear if this is down to faults or user error.

A small number give low ratings because they haven’t got the results they expect, around 10 reviewers in all. A couple of these waited less than 2 months, and they really need to try for longer.  But the rest did, leaving reviews at timeframes ranging from 3 to 8 months. These reviews represent the small percentage of people that do not respond to the treatments.

Silk'n Flash&Go Express reviews score it 4.1 out of 5There are also many neutral 3-star reviews. Most of these say it works, but you need patience because results are slow to appear. A few suggest this is probably due to starting their first treatments on the lowest intensity settings which, as one reviewer puts it “seriously sets back the advertised result timeline.” Follow the directions for a skin sensitivity test above.

For others it delays their hair growth after prolonged use, but they haven’t reached a permanent hair-free state. And a handful more neutral reviews are down to mixed experiences with much better results on some body areas versus others.

There are loads more positive reviews. Here’s what they have to say.

The good bits

Grey, protective zip-up storage case with Silk'n Flash&Go Express and power adaptor tucked away safely.

The zip-up storage case is a nice addition to protect the compact device. The North American, European and Asian power adaptors make it convenient for trips abroad too.

Most reviewers got the Flash&Go Express free of charge in exchange for their honest review. And the reviews seem genuine and in the main are helpful and informative.

Loads of reviewers love the simplicity of the Flash&Go Express. It’s easy to hold and use, there’s virtually painless and treatments are quick.

Reviewers also like the compact, portable design and multi-plug adaptors that make it a convenient travelling buddy. The protective zip-up storage case and cleaning cloth are two little touches that make a big difference too.

The helpful Silkn.com customer service team get some love in the reviews too. As does the Silk’s App. It reminds you of your intensity level and when you’re next treatment’s due for each different body area.

Loads of reviews report good results too.

The start-up phase takes a total of 14 weeks to complete. You start with 4 treatments at 2 week intervals (this takes 6 weeks), then a further 2 treatments at 4 week intervals. You’ll need top-up treatments to maintain your results too, as and when you see regrowth.

Several positive reviews say it works but don’t say how long it took to see results. Some see results from as early as the first, second and third treatments. Most begin to see results after 4 treatments (6 weeks), and this ranges from a ‘slight’ up to an impressive 80% reduction in hair.

Many encourage that you need to stick with the schedule to get good results, and these results increase over time. They report hair regrowth is softer, finer and lighter than before. Hair grows slower and slower and eventually bald patches appear. They need to shave less and less frequently too. Many need to just once a week now verses the tedious daily shaving required before using the device.

 

“after 3 or 4 treatments I have absolutely noticed that my hair has become finer and has taken longer to grow back, I am thrilled with being able to shave less and not deal with the bumps and cuts that sometimes come with shaving.”
Silkn.com reviewer

“I’m loving my Silk’n Flash & Go Express. There’s several reasons why I’d recommend it to friends and family… first, the device actually works! I’ve finished with my 8th treatment session last week and the difference in hair growth is amazing. The hair on my legs has virtually quit growing and what’s left is super fine and very sparse.”
Influenster reviewer

Some reviews report better results on some body parts than on others. But there’s no distinct pattern – it differs by review. One reviewer reports she got no results on her blonde body hair, but is still happy because the Flash&Go Express did work on her hubby’s dark chest hair!

Before you decide, let’s see what the alternatives are.

What are the alternatives?

The alternatives are the Silk’n Flash&Go Compact, the Philips Lumea Essential. But the Flash&Go Express beats them both with superior value for money and fast treatment times.

Should I buy the Flash&Go Express?

Silk'n Flash&Go Express reviewYes. Buy from silkn.com for a 60-day money back guarantee, money off and extended warranty.

It costs $100 more than the Flash&Go Compact but it’s still at a very competitive price. It’s super value when compared to other brands because you get a lot for your money. It’s a smart investment with over 15 years’ worth of full body treatments. That’s probably more than you’ll ever use. And it’s designed to give you fast treatments too, one of the fastest from this type of compact model. It’s one of the best no-frills choices out there and the user reviews love it too.

“using the the Flash&Go Express is beyond easy and within just a couple of weeks the hair on my upper lip was already becoming sparse. After about six weeks my upper lip hair is just about gone!! I am incredibly grateful for having been able to use this product – no more painful waxing for this gal!!!”
