BHA Liquid Exfoliant

Shares salicylic acid but succinic acid and sulfur are the lead actives here, meaning the exfoliation profile and skin feel are quite different from PC's straightforward 2% BHA formula.

It contains salicylic acid and green tea like the source, but it's a rinse-off physical/enzyme scrub with papain and rice bran, not a leave-on liquid exfoliant, so the salicylic acid likely isn't at a comparable leave-on strength or contact time.

This is primarily a 30% glycolic acid (AHA) peel with only 2% salicylic acid as a minor player, so it's a much harsher, differently-focused exfoliant than the BHA-only Paula's Choice product.

Salicylic acid is present but buried in a sulfate/surfactant-heavy cleansing scrub base with menthol and fragrance, so it functions more like a foaming face wash than a leave-on BHA exfoliant.

Salicylic acid is present but this is a rinse-off walnut-shell physical scrub with fragrance and sulfates, a very different exfoliation mechanism and likely much lower BHA effectiveness than the leave-on source.
