“I saw a noticeable difference in my skin after trying it for a week, and the results only got better from there. The before-and-afters are pretty amazing to look at—the way it works for every skin type—and along with all the visible benefits, I love how moisturizing it is.” —Gwyneth

For youthful, healthy-looking skin, this powerful, clinically tested all-in-one peptide serum takes a 360-degree approach to target key signs of aging—firmness, elasticity, wrinkles, hyperpigmentation, texture, radiance, barrier support, and more. The results surprised even plastic surgeon Dr. Julius Few, who conducted the clinical study. “These are some of the most powerful results we’ve ever seen with a topical treatment,” he says.

Made with peptides to address laxity and volume loss, astaxanthin-rich microalgae and phytoactive paracress for firming and lifting, black tea ferment and niacinamide for glow and a more even complexion, bifidus postbiotics and ceramides for barrier support, along with safflower oleosomes and dragon’s blood to moisturize, the serum works beautifully for all ages, all skin tones, and all skin types (including sensitive). Use it morning and night to see improvements in skin firmness, elasticity, volume loss, the appearance of static and dynamic wrinkles, vascularization, pigmentation, smoothness, luminosity, and moisturization.
