Centella asiatica is a medicinal plant whose extracts and purified triterpenes (madecassoside, asiaticoside and their acids) are widely used in Korean skin care. 'Cica' products are marketed to calm and support irritated skin.
What it does
Centella's triterpenes have anti-inflammatory, antioxidant and collagen-stimulating activity in cell and animal studies, and the plant has a long history in wound care. In cosmetics it is used to reduce the look of redness and support recovery of a stressed barrier. Small clinical studies report improved hydration, reduced water loss and less irritation, though formulas usually combine centella with other soothing ingredients, which makes its own contribution hard to isolate.
