Superior Product for Your Well-Being Imagine your skin healthy and radiant with multilevel hydration Skin naturally produces moisturizing oils that consist of several components, all in proper balance. Research shows that as we age, this balance changes. The patented L22 ingredient in Yeouth Anti-aging Moisturizer delivers the same type and ratio of lipids that is found in younger, healthy skin. By using the lipids from botanical sources and carefully recombining them to closely resemble your younger skin's natural oils. How the L22 Formula Works L22 is a patented lipid complex made exclusively from botanical sources designed to provide the same balanced skin-lipid profile of younger, healthy skin. The fatty acids of jojoba oil (wax esters) are interchanged with the fatty acids of macadamia oil (triglycerides) to form new wax esters and triglycerides with new fatty acid compositions. These new wax esters and triglycerides closely resemble those present in skin lipids. This is then combined with olive oil-sourced squalene, plant sterols, and sterol esters. The result is a lipid composition similar to that found on healthy skin. Significant Clinical Results In double-blind, vehicle-controlled clinical studies, test articles which contained L22 demonstrated superiority to other skin-lipid-like compounds when evaluated for barrier repair and skin hydration. L22 also demonstrated significant improvements in both aged and sun-damages skin, when compared to a vehicle, with regard to skin hydration, firmness, and elasticity.
