What type of ingredient is salicylic acid classified as?

Salicylic acid is primarily classified as a keratolytic and acne-fighting ingredient. As a keratolytic, it works by softening and shedding the outer layer of skin, which helps to break down excess keratin that can clog pores, leading to acne formation. This action allows for better penetration of topical treatments and promotes a clearer complexion. Additionally, it has anti-inflammatory properties that help reduce the redness and swelling commonly associated with acne.

While salicylic acid does possess exfoliant properties, its unique keratolytic function and significant role in treating acne make the classification of keratolytic and acne-fighting the most accurate representation of its primary benefits in skin care.
