Safety Guide
Evidence-based safety information for using Thiamidol for sensitive and reactive skin.
Thiamidol is generally well-tolerated by sensitive skin. As always, patch test new products.
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.
