Glycosamine from the American Lotion Crafter company

a component matching the skin, meaning it exists in our skin in the gaps between cells, and is used to maintain the skin barrier abilities and reduce dryness. Studies have shown that NAG can increase collagen production, increase skin moisture content, increase skin elasticity, increase exfoliation, and speed up wound healing. It has been proven that NAG reduces hyperpigmentation and can be combined with niacinamide to enhance its ability to reduce hyperpigmentation. N-Acetyl Glucosamine is an amino sugar with skin exfoliating properties similar to alpha and beta hydroxy acids without irritation. NAG can normalize keratin layer exfoliation, so it can be a good alternative to acid-based exfoliating ingredients that may irritate sensitive or rosacea-prone skin. Water-soluble, used at a ratio of 4 to 10%. Applied at temperatures below 50 degrees Celsius.
