Unlike retinol or strong AHAs, it doesn't cause purging or peeling. Succinic Acid pairs with it to regulate sebum and further reduce bacteria in pores.

Gluconolactone (PHA) gently removes dead skin cells from the surface — the most sensitive-skin-safe exfoliant available. Lactic Acid refines texture. Phytic Acid brightens.

Succinic Acid adds sebum regulation and additional antibacterial activity. BHA (Salicylic Acid) clears inside pores. Gluconolactone (PHA) exfoliates the surface gently.
