You'll never have to shave again. Seriously.


I hate shaving. Shaving is so annoying and time-consuming. And let’s talk about time, I mean, who has the luxury for that? Between work and keeping up with the kids, there’s barely a moment to spare. Permanent laser removal seemed like a solution. Until I realised it costs around $800 for a full treatment! So when I discovered the DIY Silk’n Flash & Go permanent hair removal, I jumped at the chance. In this article, you’ll find everything you need to know before you buy and all your questions answered. 

How does it remove hair?

The Silk’n Flash & Go uses light to zap the dark portions of your skin hiding hair follicles. The follicles deaden and slow down or stop hair growth.

Can anyone use this?

Nope. Since the light attacks dark parts of your skin, this isn’t going to work on people with naturally dark skin, or those who’ve gone tanning. Silk’n suggests you avoid tanning at all while using this, just to be safe.

Also, you can’t get this in Australia or New Zealand.

What does it come with?

The Silk’n Flash & Go comes with…

  • Flash & Go gun
  • Extra light cartridge
  • Power cord with two different plug types
  • Instruction manual
  • Instruction DVD

How do you use it?

Before you do anything, you have to shave the area that you’re going to zap. That’s right, the Silk’n Flash & Go doesn’t remove your current hair. It’s only meant to prevent it from growing back.

This is essentially like a light gun. After shaving, you plug it in, press the power button, and you’re pretty much ready to go. You can set the intensity of the light with the plus and minus buttons.

When the Flash & Go is ready, the lights will flash at either side of the purple control panel. You press the gun to your skin, press the trigger, and there will be a flash of light. As the gun charges again, you move it to the next patch of skin and press the trigger again.

Does it hurt?

It depends. When you’re doing it on tougher skin and at a low intensity, at most you’ll feel is a little warmth. On sensitive areas and at higher intensities, it will sting a little only as the light flashes. I felt this especially on my knees. You will have to be cautious as improper procedure will lead to skin damage and burns.

Does it take a long time to use?

The light that’s used to slow hair growth is relatively small. It’s only 4 cm across. That means it can take a while to cover large areas, like your legs. But small areas, like you chin or upper lip, can be complete in a minute or two.

When I was testing this out, I would do my upper lip, chin, underarms and legs (at the knee and below). I could get all that done while watching a movie.

How often do you use it?

Silk’n suggests you use the Flash & Go every two weeks at first. Then, after four treatments, you use it every four weeks if you still see hair growth.

Does it actually work?

Yes. But, if you don’t believe me, I happened to take some pictures.

One of the fastest hair growing spots is on my ankles. So, I took pictures of the same spot on my left ankle.

I started with a picture of one week after shaving before I started using the Flash & Go (without shaving for that entire week). Then a new picture one week after each Flash & Go treatment (three treatments in total).

As you can see, hair growth got sparser as the treatments went on. Hair grew in slower, too. I could go a whole week and still look like I just shaved my legs.


Do you ever need to buy light refills?

This depends. The kit comes with an extra light cartridge, so you have two to work with. I found that the first light needed to be replaced after two full treatments (which covered my upper lip, chin, underarms and legs), so I installed the second light. If your hair is particularly fickle, you might have to get one more light. Silk’n sells replacement cartridges for $45.

The Final Verdict

I’m always skeptical of stuff like this. After all, the Silk’n Flash & Go makes a big promise: permanent hair removal. While I can’t know for sure if the success I saw will last forever, I did see success. I know for sure that I won’t have to shave my legs nearly as often now. And, if I keep using it, there may come a time where I don’t have to shave at all. I’m pleased.

So, I give the Silk’n Flash & Go a…
