Silk’n Infinity 400,000 review

Silk’n Infinity 400,000 IPL

Silk’n Infinity 400,000 draws upon the latest advances for at-home hair removal. It utilizes eHPL™ (enhanced Home Pulsed Light): a ground-breaking technology, combining both Galvanic and Optical Energy sources for supreme permanent hair removal. Now it’s possible to remove hair on all skin colours by widening the skin pores and enabling the light to penetrate deeper into the hair follicle.

Here’s our Silk’n Infinity 400,000 IPL Removal Review.

PROS (acording to the manufacturer)

  • 400,000 flashes. 5 energy levels

    400,000 flashes (+30% vs previous Silk-expert 5) deliver an equivalent of 22 years of treatment. The 400,000 light pulses are also cost-effective, because there is no need for refill cartridges, saving you additional money. There are 5 energy levels which you can configure separately according to your skin/hair colour and they also help removing the hair twice as fast as other products.

  • Uses eHPL

    Silkn has further developed the world-famous HPL technology with galvanic and optical energy. The combination of these allows for much more efficient hair removal as it opens the skin pores, allowing the light pulses to better reach the hair follicle.

  • Very fast IPL.

    Treat both legs in less than 5 minutes at the lowest energy level. 2 times faster than the previous Silk-expert 5. The Silk’n Infinity 400,000 IPL hair remover allows a full body treatment in less than 20 minutes. And all without pain, skin irritation or ingrown hairs.

  • Suitable for all skin tones and most hair colours

    The Silk’n Infinity is suitable for all skin tones, including the darkest skin colours and almost all hair colours. That includes redheads, blondes, and greys. It also has a unique built-in Skin Colour Sensor, which stops the device from emitting a strong light pulse if your skin tone is too dark. The clever safety mechanism means that light can only emit upon contact to your skin.

  • Pulsing or Gliding method

Thanks to the super rapid light pulses, treatments are completed by Gliding (for large areas) or Pulsing (for small areas).

  • Clinically proven

Previous studies have proven that the sole use of low energy pulsed-light (Optical Energy) is effective for long-term removal of unwanted hair on light skin*; 1 month following 6 bi-weekly treatments, the average hair reduction percentage was 92.3%*. An additional study with the Infinity specifically showed that the addition of Galvanic Energy enabled hair removal on dark skin as well**.

PROS – according to us!

  • Not too painful
  • Easy to control
  • After eight to 12 weeks, hair grew back thinner and more sparse

Price The device can be bought for about £287,53 on amazon which, does seem reasonable when compared with some of the other products in this category, also nice!

Speed – It allows quick sessions, which is great, but it takes longer on dark skin or lower intensties.


Looks – It is a compact hair removal device and has a light-weight design and the fact that it comes with a sleek carry bag makes it even more attractive for travelling and general storage.



Before you start zapping away, first read the user manual and do a skin sensitivity test.


The Infinity device is slightly bigger than expected, but still compact compared to other devices. The design is still simple, clean and functional with a large button. It’s light-weight (228g), so it feels good to hold and is easy to manoeuvre. The simple controls and  mains-power cable are tucked away on the base.

The lamp lifetime of flashes from the Infinity is extremely good.



One disadvantage of this depilation device is that it is a time-consuming and lengthy process of body depilation. Nevertheless, this IPL device performs better on average than many comparable products.



GET RID OF UNWANTED HAIR! I started by going to a salon and having my chin and upper lip zapped. Initially it was painful but as the hairs started to diminish the pain was less and less. When I was through, I purchased my own in order to remove hair on my arms and legs. It definitely does work. Occasionally a few stragglers get through, but just take care of them.
I wish I would have started before I began to get some gray hairs or tweezing.
So finally if you have patience it does work!”

Ease of use. No-frills, compact, light-weight design. Clever skin tone sensor detects darker tones and activates only the low, safe intensities. Quick sessions.”

Bye Bye Hair! I was excited about this and seemed to have slightly more technology behind it than other brands!
I have been trying to find a more permanent method than epilating, which i actually don’t mind! There are many big brands that come to mind when i search IPL home devices. I Decided to go for something that had newer technology and abut more design!
I was very impressed with the box and it immediately spoke out to me as a premium product!
The shaver was a bit cheap but worked fine. I was definitely hoping for something more substantial but its not the real product so I wasn’t too bothered.
After a good 4 treatments i dont have any hair and am very happy with results. Its easy to use and doesn’t take as long as I thought! I have zero patience, probably why i’m quite partial to epilation!
I’m pleased I have invested the money and I will go on to do my face now and share it with my sister!”


Our Verdict:

All in all, the Silk’n Infinity 400,000 IPL is a very good IPL device with which all people can achieve satisfactory results, no matter what skin and hair colour they have.
