Science
Mechanism of Action
This ingredient operates through several key mechanisms on the skin. Primarily, it acts as a surfactant, effectively reducing surface tension to facilitate cleansing. As a derivative of collagen amino acids, its low molecular weight allows for penetration into the upper epidermal layers, where it emulates natural moisturizing factors (NMFs) to bind and retain water, thereby boosting skin hydration, suppleness, and flexibility. Furthermore, its structural resemblance to natural collagen fragments is theorized to support intrinsic skin repair, potentially leading to improved elasticity, a more refined complexion, and a reduction in the visible signs of aging like lines and wrinkles.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that amino acid alkyl amides, including this ingredient, are safe when used in cosmetics at current practices and concentrations, provided they are formulated to be non-irritating. As with most surfactants, potential irritancy can occur if not properly balanced within a formulation. No specific SCCS opinion or direct FDA pre-market approval for cosmetic use was identified, as the FDA primarily regulates cosmetics through labeling and adulteration provisions.
