Tetrahydrocurcumin, a derivative of curcumin, the active compound in turmeric (Curcuma longa), is produced through the metabolic reduction of curcumin. This transformative process modifies the structure of curcumin, yielding a compound with distinct antioxidant and anti-inflammatory properties. Tetrahydrocurcumin plays a vital role in neutralizing free radicals which are highly reactive molecules that can induce oxidative stress and harm cells. By doing so, it effectively shields the skin from environmental damage, diminishes inflammation, and contributes to the promotion of a vibrant and healthy complexion.
