What This Ingredient Does

Salicylic acid is an oil-soluble exfoliant that penetrates into pores to dissolve excess sebum and dead skin cells. This helps unclog pores and reduce the formation of acne lesions such as blackheads and whiteheads.

It also has anti-inflammatory properties, which help calm redness and irritation associated with breakouts. Because of its ability to target both oil and buildup inside pores, it is widely used in acne-focused skincare.

Salicylic acid is often used alongside ingredients like niacinamide and zinc gluconate to support oil control and reduce inflammation.
