The depth of penetration of the laser beam during epilation is 1-4 mm, it reaches only to the hair follicles, then completely dissipates and never penetrates deeper than the skin! When exposed to a laser, only the hair bulb is destroyed. The laser beam slides over the surface of the skin without damaging it. The only thing that can arise after the procedure is reddening, similar to the one that occurs in a person who has been in the sun. This redness is in part an indicator of a properly performed procedure. In a few hours, this reddening passes without a trace.
