Salicylic acid is highly effective for acne and oily skin. It is oil-soluble and lipophilic, so it penetrates follicles filled with sebum, thereby helping to unclog pores, loosen and lift out blackheads, and prevent future break outs. It improves the cosmetic properties of photodamaged skin by increasing cell turnover, fading the appearance of pigment spots and melasma, and reducing roughness and the appearance of fine lines. Salicylic acid has the added benefit of absorbing some UV radiation, which can help protect the skin from the damaging effects of the sun. This type of peel can be used more frequently than the other peels without much risk of irritation and only mild flaking depending on the skin type.
