Best Salicylic Acid Serums (2026) Reviewed
Salicylic acid is the go-to BHA for clearing clogged pores, reducing blackheads, and controlling excess oil. These are the best salicylic acid serums across every budget and skin type.
What to Look For
- Concentration — Most effective serums contain 0.5% to 2% salicylic acid; higher isn’t always better for sensitive skin
- pH level — A pH between 3.0 and 4.0 allows salicylic acid to penetrate effectively; higher pH formulas are gentler but less potent
- Formula type — Water-based solutions work faster; anhydrous (oil-based) formulas are gentler for dry or sensitive skin
- Supporting ingredients — Hyaluronic acid and niacinamide offset dryness; witch hazel and zinc help control oil
- Texture — Lightweight liquids absorb quickly; gel formulas provide more hydration
