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
A red seaweed harvested and used historically in traditional East Asian, particularly Japanese and Korean, skincare and medicine for its hydrating and skin-conditioning properties derived from marine polysaccharides.
