N-Acetyl Glucosamine
N-Acetyl Glucosamine is a gentle, skin-friendly ingredient derived from glucose that helps brighten, hydrate and support a smoother complexion. Popular in modern UK skincare, it is often used as a milder alternative to exfoliating acids and works well alongside niacinamide.
How it works in skincare
In cosmetics and skincare, N-Acetyl Glucosamine functions as a precursor to hyaluronic acid and helps inhibit the enzyme responsible for excess melanin production, resulting in a more even skin tone. It also supports the skin’s natural barrier by boosting glycosaminoglycan levels, improving hydration and softness without irritation. You will commonly find it in brightening serums, creams and masks where it complements other active ingredients for a clearer, more radiant finish.

Where it comes from
N-Acetyl Glucosamine is naturally derived from the shells of crustaceans such as shrimp and crabs, where it is found in the form of chitin. In cosmetic production it is highly purified to create a skin-compatible ingredient suitable for topical use.
