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.
Soothing
Calms redness, irritation, and inflammation. Your skin's chill pill — great for sensitive, reactive, or post-procedure skin.
Locks in moisture
Traditional Use
Irish moss (Chondrus crispus) has been used in traditional Irish and European folk medicine for centuries as a demulcent and skin soother. Historically consumed and applied topically for skin health; the hydrolyzed extract is a modern cosmetic adaptation.
