Serum wrinkle removal, also known as autologous serum wrinkle removal, refers to the process of centrifuging the candidate’s own venous blood to produce autologous plasma rich in high concentrations of growth factors, which is injected into the superficial dermis. In the medical aesthetic industry, it is used to induce the regeneration of collagen and elastic fibers in the skin to achieve the effect of wrinkle removal and anti-aging. The common hazards that may occur with autologous serum injection are as follows: 1, infection: the injection operation is an invasive operation, so there is a possibility of infection. Once the infection occurs, we should go to the hospital in time to deal with it; 2, local bruising, redness: the symptoms can disappear on their own after a few days; 3, local swelling: you can use ice packs to help alleviate the situation; 4, local collapse, unevenness, cortical necrosis: the operation of autologous serum wrinkles has a high degree of instrumentation and technical requirements, and improper operation will lead to undesirable consequences. In addition, if the candidate himself has a serious lack of nutrients, may also lead to postoperative local collapse, unevenness, serious cases can lead to cortical necrosis, etc.; 5, dryness, dullness, spots, etc..
