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.
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
Traditional Use
Wakame seaweed has been used in Japanese and Korean cuisine and traditional medicine for centuries, valued for its mineral content and nourishing properties. Its use in modern skincare is a recent adaptation based on traditional food use and contemporary marine cosmetics trends.
