N-ACETYl GLUCOSAMINE
What is N-ACETYl GLUCOSAMINE?
N-Acetyl Glucosamine is a naturally occurring amino sugar derived from chitin, commonly found in shellfish shells, and is a key building block of hyaluronic acid in the skin. In skincare, it functions as a humectant, drawing moisture into the skin, while also inhibiting melanin production to brighten hyperpigmentation and even skin tone. It penetrates the skin effectively and supports the synthesis of glycosaminoglycans, enhancing overall skin hydration and barrier function.
