What is salicylic acid commonly used for in skincare?

Salicylic acid is commonly used in skincare primarily for its exfoliating properties. It is a beta hydroxy acid (BHA) that works by penetrating deep into the pores and helping to dissolve excess oil and dead skin cells. This action makes it particularly effective for treating acne and for those with oily or combination skin types. By exfoliating the skin and clearing blocked pores, salicylic acid can help reduce the appearance of blemishes, blackheads, and whiteheads, promoting clearer and smoother skin.

While hydration, anti-aging, and sun protection are important aspects of skincare, salicylic acid does not directly contribute to these functions. Hydration is typically addressed with moisturizers, anti-aging is often managed with ingredients like retinoids or peptides, and sun protection is achieved with sunscreens containing broad-spectrum UV filters. Thus, salicylic acid’s role as an exfoliant is what makes it stand out in the context of skincare treatments, solidifying it as a favored ingredient among dermatologists and estheticians for its effectiveness in improving skin texture and clarity.
