General rule: apply thinnest/most active ingredients first, thicker/occlusive ingredients last.
brightener
Thiamidol is Beiersdorf's patented tyrosinase inhibitor — a synthetic small molecule developed by Hamburg-based research labs to selectively block human tyrosinase (the enzyme that produces melanin) more potently than common alternatives like hydroquinone, kojic acid, or arbutin. Eight years of pre-launch research, decade of clinical validation, and a deep patent moat make it one of the most-distinctive brightening ingredients in modern dermo-cosmetics.
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.
