Aesculus Hippocastanum (Horse Chestnut) Extract is derived from horse chestnut seeds and is rich in the saponin aescin, which is valued for its anti-inflammatory, antioxidant, and microcirculation-supporting properties. In skincare it is commonly used to soothe skin, reduce redness, and address the appearance of puffiness and visible capillaries.
