Functions
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.
Skin Protecting
Helps rebuild and strengthen your skin barrier — the invisible shield that keeps moisture in and irritants out. Essential after over-exfoliating or harsh weather.
Nourishes & Protects
Locks In Moisture
Traditional Use
A brown seaweed traditionally used in Asian coastal communities for skin and hair health. Incorporated into modern cosmetics in recent decades for its humectant and nutrient-rich properties.
