Dermatologist Note
Salicylic acid is oil-soluble, allowing it to penetrate into pores and dissolve the sebum plugs that cause blackheads and breakouts — unlike AHAs which only work on the surface. The pH of ~3.4 ensures the salicylic acid remains in its active, un-ionized form. Widely regarded by dermatologists as the gold standard OTC acne treatment for comedonal acne.
Based on published clinical literature and dermatological research.
