Ingredient Layering
Hydroquinone and Tretinoin work great together!
Step 1
Tretinoin
retinoid
Step 2
Hydroquinone
brightener
General rule: apply thinnest/most active ingredients first, thicker/occlusive ingredients last.
brightener
The most effective depigmenting agent ever discovered. Dermatologists prescribe it when nothing else works — and nothing else works as well. Cycle it, respect it, and wear SPF or it'll rebound.
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.
