Pumpkin seeds contain antioxidants such as vitamins E, C and A, which can control free radicals in the body and protect the human immune system. After ultraviolet rays penetrate into the skin, they will produce harmful free radicals, which will destroy the elastic fibers of the skin and stimulate the secretion of melanocytes, thus leading to dryness and relaxation of the skin and accelerating aging. Therefore, it is necessary to supplement antioxidant substances to help reduce the generation of free radicals. At present, the common antioxidant substances include vitamin C, vitamin E and other antioxidant nutrients to resist aging. Obviously, pumpkin seeds contain antioxidants that women urgently need, which can well inhibit the growth of free radicals in the body, thus achieving the effect of preventing skin aging.
