exfoliant aha
Glycolic acid is the smallest AHA molecule, which means it penetrates skin more effectively than its counterparts. It dissolves the bonds between dead skin cells, revealing smoother, brighter skin underneath. Among chemical exfoliants, it has the deepest evidence base.
brightener
Niacinamide is one of the most versatile and well-researched skincare actives available. It regulates sebum production, strengthens the skin barrier, fades hyperpigmentation, and minimizes pore appearance — all with minimal irritation risk. If you could only pick one active, this would be a strong contender.
