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.
Soothing
Calms redness, irritation, and inflammation. Your skin's chill pill — great for sensitive, reactive, or post-procedure skin.
Humectant
A moisture magnet. Pulls water from the air and deeper skin layers up to the surface to keep skin plump and hydrated.
Nourishes & Protects
Traditional Use
A red seaweed traditionally used in Asian coastal cuisines and traditional medicine for its nutrient density and mucilaginous properties. Used historically in Japanese and Korean skincare for hydration and mineral supplementation.
