Turmeric Extract (Curcuma longa)

Ingredient context

Turmeric's curcuminoids are anti-inflammatory and antioxidant workhorses with a large research base, though it is worth being precise that most of the high-quality clinical evidence specific to skin brightening comes from oral rather than topical administration, which suits GLOW's capsule format well.

Evidence context

A randomised, double-blind, placebo-controlled trial of a low-dose, water-dispersible turmeric extract found measurable improvements in facial skin health parameters over the study period, and separate dermatology reviews describe curcumin's ability to reduce tyrosinase activity and interrupt melanogenesis, giving it a supporting role in pigmentation evenness alongside GLOW's Vitamin C.
