Ingredient Layering
Kojic Acid and Vitamin C work great together!
Step 1
Kojic Acid
brightener
Step 2
Vitamin C
antioxidant
General rule: apply thinnest/most active ingredients first, thicker/occlusive ingredients last.
brightener
Kojic acid is a potent tyrosinase inhibitor derived from fungi, used extensively in Asian skincare for hyperpigmentation. It's more effective than many natural brighteners but less stable and more irritating than niacinamide — a trade-off that makes it best suited for targeted use rather than daily application.
antioxidant
Vitamin C is one of the most thoroughly researched antioxidants in dermatology. It neutralizes free radicals, inhibits melanin production, and supports collagen synthesis. The challenge is formulation stability — L-ascorbic acid oxidizes easily, and many products degrade before you finish the bottle.
