Chestnut (which may refer to horse chestnut, Aesculus hippocastanum, or sweet chestnut, Castanea sativa) has a history of traditional use for various skin conditions, including dry or flaky skin, particularly in folk medicine. In European herbal tradition, chestnut extracts—especially from the leaves or bark—were sometimes applied in topical preparations for their supposed soothing and anti-inflammatory properties. Horse chestnut seed extract is more commonly associated with vascular health (like treating varicose veins), but topical formulations for skin health can be found in some traditional remedies.

However, scientific evidence supporting the use of chestnut for dry or flaky skin is limited. Most research on chestnut focuses on its escin content and benefits for circulation, not dermatological effects. There are a few in vitro studies indicating that chestnut extracts might have antioxidant or anti-inflammatory activity, which could theoretically support skin barrier function, but clinical trials in humans are lacking. Thus, chestnut’s use for dry or flaky skin is primarily based on tradition, with only weak indirect scientific support.

In summary, while chestnut has a place in traditional medicine for supporting skin health, there is little direct scientific validation for its use specifically for dry or flaky skin.
