11 Acne-Prone Skin Treatment Steps Dermatologists Recommend

3. Salicylic acid for unclogging pores

Salicylic acid is a beta-hydroxy acid that dissolves oil and helps clear comedones inside pores. Dermatologists favor it for oily and acne-prone skin because it penetrates sebum-filled pores and reduces clogging. Use salicylic acid products—usually 0.5–2% concentrations—one to two times per week at first, then increase frequency carefully if your skin tolerates it. Chemical exfoliation is preferred over rough physical scrubs, which can irritate and worsen acne. Apply salicylic acid after cleansing and before moisturizer, and always watch for signs of over-exfoliation such as redness or peeling. If you already use a retinoid, space salicylic treatments a few nights apart to reduce irritation. For combination skin, gel or liquid formats tend to be lighter and more comfortable in humid climates. When used properly, salicylic acid helps smooth texture, reduces blackheads, and makes other treatments penetrate more effectively.
