Your good friend usually takes 7 days-14 days to return to nature completely. The principle of autologous cell wrinkle removal is to extract dermal fibroblasts from beauty seekers and culture them in vitro before blood transfusion. In practice, we usually take the full-thickness skin about the size of mung bean behind the ear or the discarded skin removed in cosmetic plastic surgery. Autologous cells were cultured, amplified and purified in vitro by tissue engineering technology. After 6-8 weeks, they reach the order of millions of cells, and then they are transfused into my wrinkled dermis. Autologous cells can get opportunities to grow, develop and mature in the maternal environment of skin. After these processes, collagen can be produced in about 3-4 weeks after injection, so that the existing wrinkles can be gradually alleviated or disappeared, thus achieving the effect of wrinkle removal.
