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.
Antioxidant
Fights free radicals — the unstable molecules from UV, pollution, and stress that break down collagen and cause premature aging.
Locks in moisture
Traditional Use
Japanese kelp has been used in traditional Japanese and Chinese medicine for centuries to support skin health and provide minerals. Valued in traditional practice for its iodine content and skin-nourishing properties.
