Functions

Humectant

A moisture magnet. Pulls water from the air and deeper skin layers up to the surface to keep skin plump and hydrated.

Skin Conditioning

A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.

Emollient

Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.

Locks In Moisture

Traditional Use

A synthetic acetylated amino acid derivative developed in the late 20th century for cosmetic use. It was created to enhance skin hydration and improve the cosmetic properties of amino acids in skincare formulations.
