About this product

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. “You really see results on your skin—next-level glow, softness, smoothness—when you use this serum. People will ask you what you’re doing. And it stays potent till you finish it.” —Gwyneth Paltrow, Founder.
