Aesculus Hippocastanum Leaf Extract

Aesculus hippocastanum leaf extract comes from the horse chestnut tree, a species native to the Balkans with a long history of use in traditional medicine for skin and vascular complaints. The extract is obtained from the plant's leaves and contains bioactive compounds including polyphenols and flavonoids.In skincare formulations, this ingredient functions primarily as a skin conditioner, working to support the skin's natural barrier function and overall comfort.

The extract's primary mechanism appears to be related to its polyphenolic content, which can reduce inflammation and support microcirculation. Research suggests these compounds may help stabilise blood vessel integrity and reduce fluid accumulation in tissue, which can improve the appearance of swelling and support overall skin resilience.The conditioning effects likely stem from the extract's ability to strengthen the skin barrier and improve hydration retention, though the precise mechanisms in topical skincare require further investigation.

This ingredient is typically found in serums, creams and targeted treatments designed to address puffiness or support skin firmness. It works best as part of a consistent routine rather than as a one-off treatment. Look for formulations that combine it with complementary ingredients such as other circulation-supporting botanicals or antioxidants for optimised results.

Horse chestnut leaf extract is generally well-tolerated in topical formulations. Those with known sensitivity to plant extracts or the Sapindaceae family should patch test first.
