A B.H.A that is lipid solublein contrast to other acids that are water-soluble. It can penetrate into the lipid plug in a congested follicle. It is an exfoliant and antimicrobial.
Salicylic acid also helps to remove dirt, bacteria, and grime that has built up on the skin’s surface so that pores can remain clear and free from irritants. By removing dead skin cells and bacteria from the skin, salicylic acid helps to purify and exfoliate, which improves skin health and appearance.
Salicylic acid has been used to treat various skin disorders for more than 2,000 years. The ability of salicylic acid to exfoliate the stratum corneum makes it a good agent for peeling. In particular, the comedolytic property of salicylic acid makes it a useful peeling agent for patients with acne. Once considered as a keratolytic agent, the role of salicylic acid as a desmolytic agent, because of its ability to disrupt cellular junctions rather than breaking or lysing intercellular keratin filaments, is now recognized and is discussed here. Salicylic acid as a peeling agent has a number of indications, including acne vulgaris, melasma, photodamage, freckles, and lentigines. The efficacy and safety of salicylic acid peeling in Fitzpatrick skin types I–III as well as in skin types V and VI have been well documented in the literature.
