What kind of ingredient is salicylic acid?

Salicylic acid is primarily classified as an exfoliator, specifically a beta-hydroxy acid (BHA). Its key function is to penetrate the pores and dissolve the debris that can lead to blemishes, making it highly effective for individuals with oily or acne-prone skin. This ingredient not only helps in sloughing off dead skin cells from the surface but also works to clear out clogged pores, thereby reducing the likelihood of acne development.

In addition to its exfoliating properties, salicylic acid also has anti-inflammatory benefits, which can soothe redness and irritation associated with acne and other skin conditions. While it is not a moisturizing agent, sunscreen agent, or a fragrance component, its role in the skincare regimen is significant in terms of treating and preventing breakouts through its effective exfoliating action.
