Photorejuvenation is a non-invasive photodynamic therapy with broad spectrum. It stimulates the skin by the photochemical action generated by intense pulsed photons of a photon rejuvenation instrument, so that the collagen fibers and elastic fibers in the dermis produce chemical changes in molecular structure, increase in number, rearrange and restore their original elasticity, thus achieving the therapeutic effect of eliminating wrinkles and narrowing pores. In addition, the photothermal effect it produces can enhance the function of blood vessels and improve the microcirculation of the skin. Generally speaking, as long as it is a regular plastic surgery hospital, it is capable of doing well. Of course, this is also related to nursing after rejuvenation.
