How this list is built: products are grouped by what they are formulated around and who they suit, drawn from public information. Order is not a ranking of quality and nothing here is paid placement. Formulas change — read the current ingredient list before you buy.
1
Dry and flaky skin that wants a physical smoothing before makeup, and people who simply prefer a scrub and will not be talked into acids. The dissolving granules make it one of the safer options in the format. It is not for blemish-prone or sensitive skin, and not for anyone using retinoids, acids or a prescription treatment.
2
Oily, congested and blackhead-prone skin, particularly around the nose, chin and forehead. It also helps the rough, bumpy texture that comes with persistent congestion. Dry and sensitive skin should approach carefully or choose a PHA instead. If you are pregnant or breastfeeding, ask a doctor before adding any salicylic acid product to a routine.
3
Oily and combination skin with persistent blackheads and a bumpy surface texture. Because betaine salicylate is milder than straight salicylic acid, it is a sensible first leave-on exfoliant for people who have reacted badly to stronger formulas. Dry and sensitive skin should still start slowly. Ask a doctor before using any BHA in pregnancy.
