Flash&Go Review: Is It Really Worth It?

By HighYa Research Team
Updated on: Jun 9, 2015

Silk’n Flash&Go claims to be a revolutionary handheld light-based system for permanently removing body and facial hair in the comfort of your own home. Silk’n Flash&Go is claimed to be easy, safe, and painless; to help you avoid waxing, shaving, or plucking; and is guaranteed to provide permanent hair removal in as little as 6 sessions.

In order to accomplish this, Flash&Go features clinically proven, FDA cleared technology (known as HPL) that uses pulses of light to heat your hairs’ roots and to destroy their ability to regrow.

Flash&Go’s unique applicator allows individuals to properly target this HPL technology and zone into any area that requires treatment, making it versatile enough to be used on larger areas, such as legs and arms, but also for sensitive areas, such as the bikini line. As such, Silk’n claims the Flash&Go can help you save hundreds on professional treatments.

As a woman, constantly battling hair regrowth seems to never end, and you probably feel that it’s something that can’t be won. But can the Silk’n Flash&Go provide meaningful hair removal, or is it just an overpriced gimmick? Consider the following:

What Is Light-Based Hair Removal?

As it turns out, the term “light-based hair removal” is quite broad and can reference several different technologies/procedures, including low-energy intense pulsed light, intense pulsed light, LHE (light, heat, and energy), and even lasers.

With this in mind, the Flash&Go website explains their technology as such:

“Flash&Go uses gentle pulses of light energy to physically disable hair growth. Light energy is absorbed by the hair follicles while the surrounding tissue remains at normal temperature. The result is a virtually painless process that eliminates hair and provides permanent results.”

What Is Home Pulsed Light?

The Home Pulsed Light technology featured in the Flash&Go is basically Silk’n’s proprietary technology rooted in light-based hair removal. Here’s how the company explains it:

“The Silk'n Flash&Go is based on Home Pulsed Light (HPL) technology which is a proprietary and patented technology of Home Skinovations Ltd. Epilation with Home Skinovations' proprietary HPL technology is enhanced by a unique acoustic effect that improves the normal process of photoepilation, enabling hair removal epilation with low level of optical energy without the need to cool the skin.”

In other words, Silk’n claims their Flash&Go combines the light energy used in traditional light-based hair removal and combines it with their “acoustic effect” to make it more convenient to remove hair in the comfort of your own home.

Is Silk’n Flash&Go Clinically Proven?

According to the Flash&Go website, “In clinical trials held by physicians, Silk'n Flash&Go was proven to safely achieve excellent hair removal results.” However, there aren’t any citations provided for these studies on the product’s website.

The Difference Between FDA Cleared and FDA Approved

With this said, keep in mind that there is an important distinction between FDA “cleared” and “approved.”

According to the FDA’s website, “cleared” means that the company has simply filed a 510(k) premarket application, and it’s “approved” after the application has been reviewed by the FDA.

However, this doesn’t mean that the FDA tests cleared or approved devices, or that they necessarily work as advertised.

Will Silk’n Flash&Go Really Work in 6 Sessions?

Here’s how Silk’n explains the process:

“Treatment sessions with Silk'n Flash&Go should be spaced every two weeks for the first three to four sessions. After that, treatments should be done if hairs have grown back and until the desired results are achieved. The total number of sessions varies from person to person, but in general, most individuals notice a reduction after four treatments, with very good results after six treatments. Most females require eight full sessions. Males tend to have more stubborn and deeper hair and may require ten to twelve treatments.”

With this said, based on Flash&Go’s FAQ, the device only affects hairs in the Anagen growth phase. As such, “it is therefore important to understand that it may take a full hair growth cycle to achieve complete results when doing any energy based hair removal,” which for some people could be as long as 18-24 months.

Finally, keep in mind that from a hair color perspective, Flash&Go is claimed to work best on darker hair (black and dark brown), with brown and light brown hair requiring more treatments for the same results. Although red, white, gray, or blonde hairs will respond minimally.

Flash&Go Side Effects

Again, according to the Flash&Go FAQ, “A small fraction of users reported some sensation of heat, redness around the hair shaft, and slight swelling. These conditions usually subsided within an hour after treatment.”

Outside of this, the company claims there weren’t any reported any side effects or damage from long-term use of a light and laser device. However, it’s important to keep in mind that you shouldn’t use Flash&Go after a sun tan (you must wait a full 4 weeks), which we’ll talk more about next.

Who Shouldn’t Use Flash&Go?

As the image below outlines, Silk’n Flash&Go should not be considered suitable for darker shades of skin, as “Treating dark skin can result in adverse effects such as burns, blisters, and skin color changes (hyper- or hypo-pigmentation).”

The good news is that Flash&Go is claimed to include a built-in Skin Color Sensor designed to measure skin tone. If the safety feature deems your skin’s pigment to be too dark or tanned, it will disable treatment.

Customer Reviews for Silk’n Flash&Go

On Amazon.com, more than 600 readers had provided feedback about Silk’n Flash&Go and rated it an average of 3.5 stars (as of 6/9/15). There, common compliments cited its effectiveness for removing hair, speedy results, and ease of use. On the other hand, some of the most common complaints referenced unpleasant experiences (redness, pain, burned skin, etc.), failure to experience hair removal results, and high prices for replacement cartridges (more about this in the Pricing section).

The Flash&Go had 4-star ratings on both Sephora.com and Ulta.com, with many of the same compliments and complaints noted on Amazon.

From a company perspective, Silk’n is a subsidiary of Home Skinovations, Inc. based out of Ontario, Canada, who held an A+ rating with the Better Business Bureau based on just 4 closed complaints. Most of these appeared to reference difficulty processing refunds and poor customer service experiences.

Silk'n Flash&Go Pricing and Refund Policy

Flash&Go is available in the following packages:

  • Flash&Go Starter Package (includes 1 cartridge with 5,000 pulses): $199
  • Flash&Go Luxx Lifetime Package (includes 1 cartridge with 120,000 pulses): $299

Regardless of the package you choose, your order will also include an instructional DVD.

Flash&Go comes with a 60-day refund policy, less S&H charges, as well as a 2-year warranty against defects in materials or workmanship. Cartridges are non-refundable.

In order to request a refund or file a warranty claim, you’ll need to contact customer service at 877-367-4556.

What’s the Difference Between the Starter and Luxx Lifetime Packages?

Other than the number of pulses notes above, the Luxx model is claimed to be best for the entire body and doesn’t require refills, while the Starter model is best for small areas and requires refills.

Outside of these differences, the two models appear to be identical.

Can Silk'n Flash&Go Get Rid of Your Unwanted Hair?

Overall, it appears that most customers who purchase the Silk’n Flash&Go are relatively pleased with its performance at permanently removing unwanted hair.

However, it’s important to keep in mind that if you’re expecting the same results as a professional light/laser hair removal treatment, and for it to work as quickly, you’re likely to be disappointed.

    CUSTOMER WARNING: Silk'n does not honor its warranties!

    • By Dinah K.,
    • Amherst, MA,
    • Dec 17, 2019
    • Verified Reviewer

    I purchased a Silk'n Glide Hair Removal pulsed technology device (Silk'n Glide 150,000 pulses) some 23 months ago. I was an appropriate candidate for using it. I read the manual very carefully, and also kept a record of the dates and areas I used it.

    One reason I felt comfortable making the purchase was their THREE YEAR WARRANTY for the device. The warranty is printed right on the box, in the user's manual, and is also included as its own booklet in 5 languages!

    It's possible that the product may work for some. It did emit pulses, which I felt; it just never decreased the hair over time. I used the product well over 30 times; it did not work for me. There's very little difference since the almost two years I started using it. I find that I still have to use other means to remove those unwanted growths of hair.

    A few months ago, I tried returning it to the store where I purchased it. The store manager suggested that I contact the company, since Silk'n does offer its THREE YEAR WARRANTY, mentioned in multiple places, as I said. I still have over another year left on the warranty, but I've tried it enough times to know that it's not going to help me. I have the boxed product, with the manual, and the receipt. I also have my notes for how/when I used the device.

    I emailed Silk'n on November 30, 2019, asking for the company to assist in a refund for the device which did not perform. I explained that the store where I purchased it referred me back to Silk'n for assistance (given the 3-year warranty). I heard from a representative who gave me a long, contorted explanation for being unable to offer a refund; she also had me wait several more days to learn that the Israeli manufacturer would not help either. As a further insult, she suggested I go to the store for a refund, even though I'd already tried that and had informed her I'd done so!

    I am very disappointed in Silk'n's company policy of not honoring their 3-year warranty. Anyone can clearly understand the words on the package, assuring a customer that they stand behind their product. Clearly, THEY DO NOT. This is a breach of faith. I'd like to warn others that Silk'n does not keep its word.

    Silk'n Flash Luxx

    • By Rhonda H.,

    • Verified Reviewer

    I've had mine for nearly four years. My underarm hair is 90% gone. Now the hair on my legs grows slower and much finer. I am shaving about once every two weeks. My issue is my cartridge needs replaced. The lifetime use...is not accurate. That part I'm very dissatisfied with.

    Bottom Line: Yes, I would recommend this to a friend

    Caution, causes hyperpigmentation

    I read the reviews carefully and decided to purchase this device. I used it precisely as directed and after 12 weeks only saw diminished hair in my hair pits BUT it caused hyperpigmentation, which is worse than the hair. It appeared on my face, neck and bikini line.

    I saw a dermatologist and found out it was from the laser. It can be lightened with another type of laser or microdermabrasion and chemical peels but had I know about this side effect I would not have used it. Hair can be removed or shaved, but the skin darkening is expensive and takes a long time to get rid of. This is true of both at home and in office laser hair removal, but if done in office at least they can fix it. I now have the same amount of hair and skin darkening.

    Do some research. I had no idea this was a possible side effect. I acknowledge that I may have needed more than 12 weeks for removal, but clearly discontinued due to the darkening. I did research before my purchase and am an ideal candidate with beautiful light skin and dark hair, but I did not discover until it was too late that is causes skin darkening.

    Bottom Line: No, I would not recommend this to a friend

    Stopped working after three uses!

    • By D. Romo,
    • Cave Creek, AZ,

    • Verified Reviewer

    I purchase the Luxx, and after three uses, the Silk'n will not flash anymore. I've called the 800-number on the box, and they refuse based on policies to take back without a receipt (this was a gift). All I wanted was a place to send this to so it can be fixed at my expense, so I am able to use it more than three times to get my money worth. This item is not worth your hard earn cash. Plus, I saw no results in the three uses that I was only given.

    Bottom Line: No, I would not recommend this to a friend
