Horse chestnut
We use an extract from the bark of the horse chestnut tree. Rich in a coumarin glucoside esculin, this extract shows venotonic activity since it increases the vascular resistance and decrease the capillary permeability. Thus, it helps reduce the appearance of eye puffiness and under-eye dark circles. Horse chestnut bark extract also possesses anti-inflammatory activity, inhibits enzyme hyaluronidase and collagenase, and exhibits potent cell-protective effects.
