Poly-L-lactic acid in the correction of age-related changes in facial skin

Age-related changes in the skin of the face and neck are the result of a number of interrelated biochemical processes occurring in various tissues (dermis and epidermis, subcutaneous fat, musculoskeletal apparatus and bone tissue). Currently, there are a number of minimally invasive techniques to correct age-related changes in the skin of the face, but the discussion regarding the clinical efficacy and duration of retention of the effect in correcting age-related facial changes continues. Poly-L-lactic acid (PLLA) is popular with specialists and is used as an effective method of correcting involutive changes in the skin of the face, however, despite the extensive experience of its use, there is not enough research in foreign and domestic literature to study the duration of retention of the effect of drugs based on poly-L-lactic acid. The article presents an analysis of the data of modern literature devoted to the study of the effectiveness of the use of poly-L-lactic acid as a method of correcting age-related changes in the skin of the face.
