Serum injection cosmetology is done by extracting one’s own blood, refining effective growth factors and active ingredients that nourish skin cells, applying them to the skin surface, opening a large number of microscopic skin channels through micro-needles, rapidly introducing growth factors and active ingredients into skin cells, promoting the regeneration of myofibroblasts, secreting a large amount of collagen, repairing elastic fibers, making the skin more delicate, smooth, firm and elastic, and improving overall skin quality. Serum injection is a highly effective and healthy beauty treatment that can achieve remarkable results in one treatment, but to achieve long-term good results, it is necessary to follow a course of treatment. Serum injections can last 9-12 months with a single treatment, and it is usually recommended to receive treatment once a month for 3 consecutive injections to maintain the effect for about 3 years. The results can be maintained for a long time by receiving treatment once every six months to once a year.
