Ingredient Layering
Tretinoin and Hyaluronic Acid work great together!
Step 1
Tretinoin
retinoid
Step 2
Hyaluronic Acid
humectant
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.
humectant
Hyaluronic acid is a naturally occurring molecule that can hold up to 1,000 times its weight in water — a claim that's technically true but slightly misleading in skincare context. It's an excellent humectant that draws moisture to the skin, but works best in humid environments or when sealed with an occlusive.
