The result of a partnership between Caudalie and the ultra-prestigious Harvard Medical School, this potent serum harnesses a patented blend of their cult-classic Resveratrol complex, alongside a vegan collagen booster and natural hyaluronic acid. Composed of 97% natural origin ingredients, this silky, oil-free formula melts into your skin for a non-greasy, supple effect. Don't believe us? The clinical trials and studies speak for themselves... In a genetic test in vitro, the concentration of the patent found in the serum was seen to be two times more effective than retinol on natural collagen production; while in a clinical study of 43 women over 56 days, it boasted a 84% satisfaction rate surrounding its firming abilities. What's more, the product boxes for the whole Resveratrol Lift collection use lighter FSC paper, allowing their carbon footprint to be reduced by 40%, while the product vessels are fully recyclable apart from any pump or cap, which can be recuperated by Teracycle in their boutiques.
