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.
Soothing
Calms redness, irritation, and inflammation. Your skin's chill pill — great for sensitive, reactive, or post-procedure skin.

Fights Bacteria

Traditional Use
Red algae has been harvested and consumed in traditional Japanese, Korean, and Celtic diets for centuries. Modern cosmetic use focuses on its polysaccharides and minerals; traditionally valued as a food and minor skincare ingredient.
