Selectivity of the
laser for epilation

Ever wondered why there are different lasers for epilation and for removing tattoos? I hope that you've never tried to "replace" one laser with another. After the article you'll never have that thoughts!


At first let's see why the laser for hair removal works on the hair only.

Lasers for epilation can be
  • alexandrite,
  • diode
  • neodymium,
but the wavelength is quite different. For example, 755 nm, 808 nm, 810 nm, and so on. Due to this wavelength, melanin is the main target. However, I remind you that melanin is also contained in the skin, so you need to carefully treat the client's appearance.

Now about why it's never possible to treat the tattooed skin with a laser epilator

Just imagine: the laser for epilation scorches the pigment in a matter of seconds. Pigment that is in the skin. You can not get it from there and cool it. In the meantime, it will burn the surrounding tissues. As a result, a burn, then a scar and a pigmentation disorder - temporary or persistent, hypopigmentation or hyperpigmentation.

I will illustrate with a couple of cases from practice. People often come to me after conducted their first procedures with "masters" who, from ignorance or from indifference to the process, touched the tattooed skin with a laser.

Story number 1.

The client decided to carry out procedures for epilation of the upper lip, while she had lip tattoos. The master did not take this moment into account and during the first procedure the laser beam hit this area. According to the story of the girl, she experienced an almost unbearable pain (one should think, if we can't tolerate even a superficial burn, but then you are burned from within the skin). Then a burn blister appeared, which healed for a very long time under the crust, after which, even with proper care, a scar was formed. I remind you, the scar on the face, in the area of the lips. As I said, it is impossible to get rid of scars. Can you imagine?

Story number 2.

Here, the tattoo in the area of the bikini zone became the target. Everything is exactly the same as in the first story. The master neglected safety techniques and began the procedure without paying attention to the tattoo. The result is the same: unbearable severe pain, a painful burn, a long-lasting blister, a scar for the rest of her life.

Such stories always seem to me savagery, because in our time there are well-founded and tested techniques, guidelines and recommendations for conducting procedures and preventing complications and side effects. But no! There are "masters" who still prefer to put experiments on their clients and don't really strive to become real masters.

That's why I strongly recommend and warn - before you conduct any procedure, please, examine it thoroughly, you can!

Bonus. Experiment

I clearly explain how reasonable it is to approach medical equipment.

The following parameters were established:
  • fluence 50 J / cm2,
  • power 95%,
  • pulse width 45 ms,
  • frequency 4 Hz.
So. I put the laser to the light skin, on which there is almost no hair. Actively move it on the skin. No burns, blisters or anything else.


And now let's conduct the same operations with a sheet of paper with a black pigment on. The laser burns through the pigment! It's easy to imagine that the consequences would be sad if this pigment was not on the sheet, but in the skin. I think that is enough!
