Aesculus Hippocastanum Extract.
Origin: Aesculus Hippocastanum is native to a small area in the Pindus Mountains mixed forests and Balkan mixed forests of south east Europe. However, it can be found in many parts of Europe, the United States and Canada.
Skin benefits: Horse Chestnut extracts contain saponins, known collectively as ’aescin’, which have a gentle soapy feel, and are potent anti-inflammatory compounds. Saponins, such as escin, also reduce capillary fragility, and therefore help to prevent swelling, thus, eye-puffiness. An extract of horse chestnut has recently been shown to have one of the highest ’active-oxygen’ scavenging abilities of 65 different plant extracts tested. Such extracts are more powerful anti-oxidants than vitamin E, and also exhibit potent cell-protective effects, which are linked to the well-known anti-ageing properties of anti-oxidants. The extract is also rich in a number of flavonoids, such as derivatives of quercetin and kaempferol. Flavonoids also have protective effects on blood vessels, and are well-known, powerful anti-oxidants.
The primary component of Horse Chestnut extract is Aescin. Aescin has been shown to inhibit hyaluronidase, an enzyme that can break down the hyaluronic acid found in our skin. As our skin uses this as a moisturizing component, a reduction in this enzyme can lead to an increase in skin hydration.
