Science
Mechanism of Action
As the active coenzyme of Vitamin B1, Thiamine Diphosphate plays a critical role as a cofactor for enzymes within key metabolic pathways, including the Krebs cycle and the pentose phosphate pathway. These pathways are essential for glucose metabolism and ATP synthesis, thereby ensuring adequate cellular energy for the skin. This energy fuels skin cell vitality, renewal, and repair functions. Beyond its energetic role, ThDP also provides antioxidant benefits, combating free radicals, and supports the skin's natural defense mechanisms, enhancing barrier function, proper hydration levels, and overall skin texture and tone.

Safety Profile
No specific Cosmetic Ingredient Review (CIR) or SCCS reviews for topical Thiamine Diphosphate are available. It is listed by COSMILE Europe as a skin conditioning agent and is subject to general EU cosmetic regulations. While thiamine (Vitamin B1) is an FDA-recognized nutrient in food, reported allergic reactions, including anaphylactoid responses, have been associated with large intravenous doses of thiamine, not topical application. One source suggests it is 'suitable for sensitive skin types' and 'unlikely to cause allergic reactions or irritations' in cosmetic use, although this appears to be a manufacturer's claim.
