Due to various circumstances, people sometimes resort to such radical methods of body decoration as permanent makeup and artistic tattoo. But every person has a moment when he has to part with a tattoo: career, age, as well as poorly executed “floating” tattoo - all this can seriously ruin life.

The ability of lasers to non-specifically damage hair follicles was noted about fifty years ago in the first studies of the effects of lasers on human skin. The concept of selectively affecting a specific chromophore based on its absorption spectra and size was not implemented in practice until the advent of the theory of selective photothermolysis, proposed by D. Perrish and R. Anderson from Harvard Medical School. The theory of selective photothermolysis makes it possible to selectively target pigmented hair follicles using hair shaft melanin as a chromophore. Melanin is a chromophore for light with wavelengths in the red and near infrared regions of the electromagnetic spectrum. However, to achieve the effect of lifelong hair removal, the biological target must be follicular stem cells located in the dermal papilla. The effect of laser hair removal can be temporary if the stem cells of the follicle have not been completely destroyed during treatment, mainly due to the induction of a catagen-like state in the pigmented hair follicles. When using a lower energy flux, the temporary effect of laser hair removal is much easier to achieve than permanent hair removal. The long-term effect of epilation depends on the color of the hair and skin and the radiation energy transferred. A long-term removal effect can occur for about 15-30% of hair with each application of the procedure, provided that the processing parameters are optimally selected The effect of laser hair removal can be temporary if the stem cells of the follicle have not been completely destroyed during treatment, mainly due to the induction of a catagen-like state in the pigmented hair follicles. When using a lower energy flux, the temporary effect of laser hair removal is much easier to achieve than permanent hair removal. The long-term effect of epilation depends on the color of the hair and skin and the radiation energy transferred. A long-term removal effect can occur for about 15-30% of hair with each application of the procedure, provided that the processing parameters are optimally selected The effect of laser hair removal can be temporary if the stem cells of the follicle have not been completely destroyed during treatment, mainly due to the induction of a catagen-like state in the pigmented hair follicles. When using a lower energy flux, the temporary effect of laser hair removal is much easier to achieve than permanent hair removal. The long-term effect of epilation depends on the color of the hair and skin and the radiation energy transferred. A long-term removal effect can occur for about 15-30% of hair with each application of the procedure, provided that the processing parameters are optimally selected predominantly due to the induction of a catagen-like condition in the pigmented hair follicles. When using a lower energy flux, the temporary effect of laser hair removal is much easier to achieve than permanent hair removal. The long-term effect of epilation depends on the color of the hair and skin and the radiation energy transferred. A long-term removal effect can occur for about 15-30% of hair with each application of the procedure, provided that the processing parameters are optimally selected predominantly due to the induction of a catagen-like condition in the pigmented hair follicles. When using a lower energy flux, the temporary effect of laser hair removal is much easier to achieve than permanent hair removal. The long-term effect of epilation depends on the color of the hair and skin and the radiation energy transferred. A long-term removal effect can occur for about 15-30% of hair with each application of the procedure, provided that the processing parameters are optimally selected device for laser hair removal .
