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
A modern ingredient developed in the 20th century by hydrolyzing milk proteins to create smaller peptide chains for better skin absorption. Used in contemporary skincare as a conditioning and moisturizing agent without traditional historical use.
