Is Castanea Sativa (Chestnut) Seed Extract a Good Ingredient?
Evidence for significant skin benefits is limited; it may offer mild antioxidant and calming effects, but the data are modest and composition can vary, which is why it's rated Fair. Botanicals can also trigger irritation or sensitization in some users, so results and tolerance may differ.
