Hyper-Pigmentation
Pigmentation forms in stages, so the best results come from serums that combine ingredients that work on different parts of the melanin process: antioxidants to calm the triggers, vitamin C and alpha arbutin to slow melanin production, niacinamide to stop it reaching the surface, and acids and retinoids to shed what's already there. Formulas like Zelens Lumino and Votary Vitamin C Glow bring several of these together in one serum. Remember to add your daily SPF to protect the results.
