Pumpkin description

Plant whose seeds are a rich source of fatty acids and several antioxidant components, including carotene, lutein, and various cartenoid pigments. Pumpkin oil is a rich source of the skin-restoring ingredient linoleic acid and antioxidant vitamin E. Pumpkin does not contain fragrance chemicals that are sensitising to skin, and as such can be considered a beneficial plant ingredient. Enzymes naturally present in pumpkin are often claimed to be alternative exfoliant/peel ingredients for skin. There is no substantiated research supporting the efficacy of exfoliating skin with pumpkin enzymes. In all likelihood, the enzymes do not remain active or stable once they are added to a cosmetic product.
