Vitamin E is a group of fat-soluble vitamins, including tocopherol and triene tocopherol. All have antioxidant function, which is necessary for the normal growth and reproduction of animals. Can be used for preventing and treating burn, frostbite, capillary hemorrhage, climacteric syndrome and caring skin. Moisturizing the skin has certain effect, but the effect is not obvious. Moreover, it is summer, which is a season with high incidence of various epidemics. Using expired vitamin E will not only have a good moisturizing effect, but may lead to various allergic or rejection reactions in the body. It is recommended not to use expired products at will! I am a high school student, and my teacher told me about the dangers of expired drugs. I hope it helps you!
