If you’ve been googling ‘best exfoliant,’ you’ve probably landed on two names: salicylic acid and glycolic acid. They both promise smoother, brighter, clearer skin but work in fundamentally different ways.
Salicylic Acid (BHA): The Pore Cleaner
Oil-soluble. Cuts through sebum inside pores. Best for oily/acne-prone skin, blackheads, enlarged pores.
Best products: Paula’s Choice 2% BHA, CeraVe SA Cleanser
Glycolic Acid (AHA): The Surface Smoother
Water-soluble. Dissolves dead skin bonds on surface. Best for dullness, texture, hyperpigmentation, fine lines.
Best products: Pixi Glow Tonic, The Ordinary Glycolic Acid 7%
Head-to-Head
Acne: Salicylic wins. Anti-aging: Glycolic wins. Blackheads: Salicylic. Hyperpigmentation: Glycolic. Sensitive skin: Salicylic (anti-inflammatory). Oily skin: Salicylic. Dry skin: Glycolic + moisturizer.
Can You Use Both?
Yes, but alternate nights. Never layer them together. Start low, go slow, moisturize more, and wear SPF religiously.
