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.
Film Forming
Creates a physical seal on skin to lock moisture in and keep irritants out. The "slugging" ingredient — barrier protection.
Humectant
A moisture magnet. Pulls water from the air and deeper skin layers up to the surface to keep skin plump and hydrated.
Locks in moisture
Traditional Use
Spongin is a protein derived from natural sea sponges, traditionally used in European skincare for gentle exfoliation. Hydrolyzed spongin was developed in modern cosmetics as a sustainable protein source with skin-conditioning properties.
