A youth activating serum with rhamnose plant sugar that creates collagen and smooths wrinkles.
YSL Forever Youth Liberator Serum is the standout product of the Forever Youth Liberator skincare product line from fashion house YSL. This serum contains the highest concentration of Glycanactif™, which is made from rhamnose, which is a plant sugar. This plant sugar purportedly acts as a cell-communicating ingredient which has an affinity for cells that produce fibroblasts. Fibroblasts are cells that create collagen, which is great for wrinkles, but all studies on rhamnose by YSL or Vichy, YSL’s sister company have been done in a lab, not on a person.
