Is there any radiation to the skin from photon rejuvenation?

Hello, photon rejuvenation technology is the use of intense pulsed light direct irradiation of the skin, resulting in photobiochemical effects, on the one hand, can make the skin in the regeneration of collagen fibers and elastic fibers can be rearranged to restore the skin elasticity and improve the microcirculation of the face, eliminating or reducing the wrinkles; on the other hand, the intense pulsed light penetrates the skin, by the organization of pigment clusters and the priority of the selective absorption of the capillaries, the thermal energy in the absence of damage to the Under the premise of normal skin tissues, it can make blood coagulate and pigment clusters be destroyed by thermal decomposition, so as to treat capillary dilatation, get rid of pigmented spots and remove unwanted hairs. Photon radiation is the range of human body can withstand, the human skin will not produce any adverse reaction,
