In cosmetic formulations it is used as a conditioning agent and humectant that helps support skin smoothness and a hydrated appearance. It is water soluble and typically used at modest concentrations.
Safety & warnings
Acetyl glucosamine is generally well tolerated and is non-comedogenic at typical use levels. Material sourced from shellfish could be a consideration for individuals with shellfish allergies, though many cosmetic grades are fermentation-derived.
