Overview
Castanea sativa seed extract is an antioxidant and astringent extract of edible chestnut seeds. The edible chestnuts are a specialty food, eaten roasted or made into pastries and desserts.
The chestnut seed is starchy, with very little protein or fat. The nut is covered in a brown hairy pellicle which is a great source of astringent tannins.
In skincare, the chestnut extract can be used for its antioxidant activity, the tightened feeling it provides to the skin, and the oligosaccharides, which might have slight humectant moisturizing properties.
Unfortunately, not much is known about the effects of chestnut seed extract on the skin.
