Salicylic Acid for Acne (Acne Vulgaris)

Goes into your pores and dissolves the oil and dead skin clogging them. Best for blackheads, whiteheads, and oily, acne-prone skin.

Why it works for Acne (Acne Vulgaris)

Unclogs pores by clearing out the dead skin and oil that block them. It is a BHA (beta-hydroxy acid), and because it dissolves in oil it can get down into oily, blocked pores in a way that AHAs cannot. At 0.5-2% it breaks up the plug, stops new clogs from forming, and calms a little inflammation. That oil-loving quality makes it the go-to exfoliant for acne-prone skin. AAD and European guidelines recommend it as a first-choice over-the-counter treatment, used on its own, for blackheads, whiteheads, and mild pimples.

How Salicylic Acid works

Oil-soluble exfoliant that penetrates sebum to dissolve intra-follicular keratin plugs.
