General rule: apply thinnest/most active ingredients first, thicker/occlusive ingredients last.
exfoliant aha
The gentlest AHA of the bunch — exfoliates AND humectants in one, so skin comes out glowy instead of tight. The glycolic for people who can't hack glycolic.
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.
