About this ingredient
Thiamine Diphosphate is the coenzyme form of vitamin B1. INCI: Thiamine Diphosphate. In cells it takes part in energy metabolism; in cosmetics it is marketed as a component for skin vitality. The role of vitamin B1 matters when taken orally, but cosmetics act topically, which is a different context. Topical clinical data that applying thiamine diphosphate gives a measurable skincare effect are limited, so it is a supporting component rather than a lead active with a proven result. Pregnancy safety. Topical use, low systemic absorption, no evidence of harm. It can be used during pregnancy and lactation. Tolerance. Irritation and allergen potential are low.
