Horse Chestnut is quite a common and often used ingredient thanks to a couple of nice magic properties. It contains the active ingredient called escin that helps to maintain healthy blood circulation and strengthen capillaries. This makes horse chestnut useful for rosacea prone skin and it’s also often used in toners for a fresh skin feeling.
It also has some anti-inflammatory and wound healing properties, so all in all, a nice one to spot on the ingredient list.
