- Verified review: A review linked to a confirmed purchase on Shopify, Amazon, Walmart, or TikTok Shop. All 13,134 reviews in this study are verified purchases.

🔬 Why Turmeric Works for Melanin-Rich Skin
How curcumin works: Curcumin (turmeric's active compound) inhibits tyrosinase enzyme activity by 40-50% (Vaughn et al., 2016). Tyrosinase is the enzyme responsible for melanin production. By slowing this enzyme, curcumin helps fade dark spots without the harsh side effects of hydroquinone.
Curcumin also reduces inflammation (Hewlings & Kalman, 2017), which can trigger post-inflammatory hyperpigmentation (PIH)—a common concern for melanin-rich skin after acne, cuts, or irritation.
AMVital's 4-Gen Turmeric Brightening System™ pairs turmeric with kojic acid (which inhibits tyrosinase through copper chelation) and vitamin C for multi-pathway brightening safe for daily use.
