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.
Antioxidant
Fights free radicals — the unstable molecules from UV, pollution, and stress that break down collagen and cause premature aging.
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
Discovered as a single-celled green algae in the early 20th century and studied for nutritional content. Modern use in skincare emerged in the 1960s when Japanese researchers identified its antioxidant and skin-conditioning properties.
