Peeling is a skin beauty treatment that uses chemical agents to remove old keratin deposits remaining on the skin's surface and inside pores. It helps regulate disruptions in skin turnover, which can cause skin problems, and is expected to improve skin beauty. Turnover, the skin's renewal cycle, is essential for maintaining healthy skin. When this cycle is disrupted due to factors like aging, old keratin tends to remain on the skin, leading to issues such as dullness and clogged pores. Acids like fruit acids (AHA), used in peelings, work to loosen and exfoliate the skin's stratum corneum to the upper layers of the epidermis. This process is expected to help remove residual old keratin and impurities from the skin and aid in skin turnover. It is recommended for those concerned about acne, blackheads, dullness, etc. The salicylic acid macrogol peeling performed at our clinic is a chemical peeling also recommended for improving skin firmness. It not only removes old keratin but is also expected to promote collagen production. Therefore, it is effective not only for dullness and acne scars but also for wrinkles and sagging.
