General rule: apply thinnest/most active ingredients first, thicker/occlusive ingredients last.
retinoid
Tretinoin is the gold standard of anti-aging and acne treatment — and it's not even close. Unlike retinol, which needs to convert twice before it becomes active, tretinoin IS the active form of vitamin A. It's prescription-only for good reason: it works faster and more powerfully than anything over the counter, but it also causes more irritation. The K-beauty approach to tretinoin is all about buffering, hydrating, and supporting the skin barrier while the tret does its job.
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.
