Functions
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Humectant
A moisture magnet. Pulls water from the air and deeper skin layers up to the surface to keep skin plump and hydrated.
Soothing
Calms redness, irritation, and inflammation. Your skin's chill pill — great for sensitive, reactive, or post-procedure skin.

Traditional Use
Derived from chitin (found in shellfish shells), NAG was developed in the late 20th century as a skincare ingredient. It became popular after research in the 2000s suggested it could support skin hydration and reduce fine lines by promoting hyaluronic acid production.
