How is salicylic acid typically used in skincare?

Salicylic acid is widely recognized in skincare for its efficacy as an exfoliant. It is a beta-hydroxy acid (BHA) that penetrates the pores, helping to dissolve the bonds between dead skin cells. This action promotes the shedding of these cells, leading to smoother skin texture and the prevention of clogged pores, which can help reduce acne. Furthermore, its anti-inflammatory properties make it beneficial for individuals with acne-prone or oily skin.

While it may assist with skin texture and clarity, its primary use is not as a moisturizer, pigment corrector, or sunblock. Moisturizers typically contain hydrating ingredients, pigment correctors focus on addressing discoloration, and sunblocks are formulated to provide protection against UV radiation. Therefore, salicylic acid's primary role in skincare is indeed as an effective exfoliant.
