Chemical peels work by using a chemical solution to remove damaged outer layers of the skin, promoting the growth of new, healthier skin cells. The chemical solution penetrates the skin and removes dead skin cells, excess oil, and other impurities from the skin’s surface. Depending on the strength of the solution and the type of peel used, the chemical solution can also penetrate deeper layers of the skin, leading to more significant changes in skin texture, tone, and appearance.
Chemical peels use a variety of chemical solutions, including alpha-hydroxy acids (AHAs), beta-hydroxy acids (BHAs), retinoids, trichloroacetic acid (TCA), and phenol. These chemicals work by breaking down the bonds between the dead skin cells on the surface of the skin, allowing them to be shed more easily. This exfoliation process also stimulates the skin’s natural healing response, encouraging the growth of new collagen and elastin fibers in the skin.
Superficial peels , which use mild acids like AHAs and BHAs, work on the outermost layer of the skin, the stratum corneum. These peels are typically used to improve the texture and appearance of the skin, reduce fine lines and wrinkles, and unclog pores.
Medium-depth peels , which use stronger acids like TCA, penetrate deeper into the skin, reaching the papillary dermis. These peels can help reduce the appearance of fine lines, wrinkles, and sun damage, as well as improve skin tone and texture.
Deep peels , which use phenol, penetrate even deeper into the skin, reaching the reticular dermis. These peels are typically used to treat more severe skin conditions, such as deep wrinkles, acne scars, and sun damage.
Overall, chemical peels can improve the appearance of the skin, reduce the signs of aging, and address a range of skin concerns.
