“As we progress into our forties, fifties, and beyond, our skin cells turn over less frequently, causing a duller appearance,” says Longwill. That’s where pumpkin can help. It contains an enzyme that gently peels away dead skin, speeding the production of new cells. In addition, pumpkin is rich in essential fatty acids, which hydrate the skin, and the antioxidant vitamins A and C, which fight free radicals that can age skin. Look for pumpkin products in facial and body peels and in treatments for the hair and scalp.
