An important distinction: Excess glucose in your bloodstream from a sugar-loaded diet is bad news for skin, but glycans, complex saccharide chains—i.e., sugars—found naturally in the body, are anti-aging miracle workers. They form the gel-like substances between skin cells that provide plumpness while also acting as antennae that send intercellular messages, but they diminish as we age, limiting the skin’s ability to regenerate as it did when it was young. Yves Saint Laurent’s new Forever Youth Liberator line boasts a patented Glycanactif complex that restores three of the key glycans commonly lost in aging skin so that the skin can rebuild itself from the inside out.
“What we’ve been able to do is look at the very long chains that make up glycan structures, isolate the specific parts that send the key messages, and then synthesize them in the lab,” says Professor Peter H. Seeberger, director of the department for Biomolecular Systems at Germany’s Max Planck Institute and a developer of Glycanactif.
This amped-up glycan activity, YSL claims, will result in better production of hyaluronic acid, promote thickening of the epidermis, speed cell turnover, and fortify the intercellular structure, resulting in firmer, more even-toned skin.
