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.

Film Forming

Creates a physical seal on skin to lock moisture in and keep irritants out. The "slugging" ingredient — barrier protection.

Locks in moisture

Traditional Use

Cassia angustifolia (senna) seeds have been used in Ayurvedic and traditional Chinese medicine for centuries, primarily as a laxative, though the polysaccharide extract is a modern cosmetic ingredient developed to provide hydration and skin conditioning properties.
