Goop Beauty 20% Vitamin C+ Advanced Brightening Serum, 30 ml | Dermstore

This supercharged daily brightening serum contains 20% L-ascorbic acid-a potent dose of the purest form of vitamin C-to visibly target dullness and discoloration. Skin-soothing ectoin, an antioxidant powerhouse, works synergistically with ferulic acid to improve the look of skin tone and texture. The unique two-part system features a hydrating hyaluronic acid serum activator designed to be mixed with the antioxidant powder before the first use to maximize performance and freshness. The result is noticeably smoother, softer skin with a remarkable glow. | Goop Beauty 20% Vitamin C+ Advanced Brightening Serum, 30 ml | Dermstore
