Why we use it

Glutamine is the most abundant naturally-occuring amino acid in the human body, and plays a crucial role in countless biological processes. It’s also very fragile, and breaks down quickly in cosmetic formulas. Acetyl glutamine is a stabilized form, made by adding an acetyl group to the glutamine molecule. Acetyl glutamine can help strengthen the skin barrier and increase hydration.
