Tetrahydrocurcuminoids
What is Tetrahydrocurcuminoids?
Tetrahydrocurcumin is a hydrogenated metabolite of curcumin, derived from the rhizomes of turmeric (Curcuma longa). This polyphenolic compound appears colorless and odorless, unlike its yellow parent curcumin, making it suitable for clear cosmetic formulations. In skincare products, it serves primarily as an antioxidant and skin conditioning agent. It functions by neutralizing free radicals, helping to stabilize emulsions and oils against oxidative degradation. Additionally, its chemical structure allows it to integrate into oil-based and water-based systems, enhancing product shelf life and supporting skin barrier integrity through protective mechanisms. Commonly found in serums, creams, and lotions targeting oxidative stress.
