N-Acetyl Glucosamine or also known as NAG, is commonly used to calm down and heal of the stressors for skin, especially during aging, is too much UV radiation that may overload an impaired antioxidant system in older and less efficient skin. One study has found that NAG reduces the amount of free radical damage from UV radiation to fibroblasts, in turn preventing the activation of enzymes that break down skin collagen and accelerate skin aging.INCI: N-Acetyl GlucosaminePurity: 100%Physical Form: White PowderSolubility: Water up to 25%Applications: TopicalUsage Rate: Up to 10% (start at a 1% or lower)Another study shows that NAG increases the rate that skin fibroblasts make hyaluronic acid and collagen, while simultaneously lowering inflammation in skin. The researchers noted that aging fibroblasts exhibited more youthful behavior under the influence of NAG, much less likely to “retire” from useful service. The researchers concluded that “NAG-induced changes in the skin fibroblasts' properties maybe important for prevention of the age-dependent changes in its structure and function.” This new research expands the value of NAG for human health beyond its well known role for better digestive integrity. It is clearly a skin anti-aging nutrient.
