Questions about escin
What is escin?
Escin is a complex of saponins — naturally foaming plant molecules — extracted from the seeds of the horse chestnut tree. It is one of the most established botanicals in eye-area cosmetics, prized for helping the delicate skin around the eyes look fresher, smoother and less puffy.
What does escin do for the eye area?
Used consistently, escin helps visibly reduce the look of under-eye puffiness and heaviness, so the eye contour appears more rested and awake. Results build gradually: in cosmetic studies of escin-based creams, the look of under-eye bags improved over several weeks of daily use.
Does escin help with dark circles?
Escin is often chosen for tired-looking eyes overall — puffiness first, with the look of dark shadows benefiting as the area appears fresher and smoother. It is frequently paired with caffeine in eye formulas; The Nine Aurora does exactly that, alongside magnolia bark extract, squalane and sodium hyaluronate.
Where does escin come from?
From the glossy brown seeds of the horse chestnut tree, Aesculus hippocastanum — a tree lining avenues across Europe. The seeds are inedible, but their saponin complex, purified as escin, has found a lasting place in fine cosmetics for the eye contour.
