About this product
Oil-soluble exfoliant that penetrates pores to dissolve blackheads and excess sebum at the source. Gentle betaine salicylate is less irritating than traditional salicylic acid.
Why BHA 4% (Betaine Salicylate) works
BHA 4% (Betaine Salicylate) is oil-soluble and penetrates pore walls to dissolve sebum and dead cell buildup from inside the follicle.
Best for these skin types
Concerns addressed
Look for BHA (salicylic acid) to unclog pores and niacinamide to calm inflammation.
BHA, niacinamide, and clay-based products help minimise pore appearance by controlling sebum.
AHA/BHA chemical exfoliation smooths rough patches, while hyaluronic acid plumps for a refined finish.
