AHA vs BHA: Which Exfoliant Makes More Sense for Your Routine?

AHA vs BHA explained: glycolic acid, lactic acid, salicylic acid, routine fit and over-exfoliation.

AHAs and BHAs are both exfoliating acid categories, but they are not identical. Choosing between them should begin with the type of result you want, not with which acronym is more popular.

AHAs in a nutshell

Alpha hydroxy acids include glycolic and lactic acid. Cosmetic AHA products are often chosen to improve the look of surface texture and dullness.

BHAs in a nutshell

Salicylic acid is the best-known BHA in skincare. It is oil-soluble and is commonly used in products marketed toward clogged pores and oily or blemish-prone skin.

Do not stack exfoliants just because you can

An AHA toner, BHA serum, retinol and scrub can turn a routine into an irritation experiment. If you already use a retinoid-style product, ask whether another exfoliant is genuinely solving a separate problem.

Frequency matters

Many people do not need daily exfoliation. Follow product directions and adjust based on tolerance. More frequent use is not automatically more effective.

ShopTapier takeaway

Choose AHA when your priority is surface texture and radiance; consider BHA when oiliness and clogged-looking pores are more central. Start with one exfoliating strategy, not a collection.
