Functions

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

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.
