What is thiamidol? Thiamidol is a patented melanin inhibitor from Beiersdorf that works at a deeper stage of melanin production than most brightening ingredients, making it highly effective.

How is it different from other brightening serums? Thiamidol is more effective than many common brighteners (kojic acid, arbutin, AHAs) due to its targeted mechanism.
