The Horse Chestnut is part of the Hippocastanaceae family, with large pink or white flowers. It should not be confused with the common chestnut as they are poisonous. However, its seeds, leaves and bark have many properties and have been used in traditional medicine for many years. In beauty, horse chestnut extract has many applications, being a good astringent and antioxidant, widely used in hair and body care.

Horse chestnut extract has been shown to promote blood circulation, thus helping to reduce visible redness in the skin and promote an even skin tone.
