Vitamin E is a fat-soluble vitamin whose hydrolysis product is tocopherol, one of the most important antioxidants. It is insoluble in water, but can be dissolved in organic solvents such as fat and ethanol, and natural vitamin E is mainly found in plant seeds. Oral vitamin E can improve lipid metabolism, prevent coronary heart disease to some extent, and has a good toning effect on women. It can also protect the skin from UV rays and pollution, and reduce scarring and pigmentation. In addition to internal use, vitamin E can also be used externally. Many skin care products include vitamin E as an ingredient for moisturizing and antioxidant effects. It is worth mentioning that most of the vitamin E softgels on the market for oral use include oil-based ingredients such as safflower seed oil and perilla oil, because vitamin E is a fat-soluble vitamin, so adding such oil-based ingredients helps the body absorb it. So if you choose to buy vitamin E softgels and then puncture the contents and add them to creams and other DIY treatments, some people need to pay special attention, such as people with oily skin, because too much of this oil-containing vitamin E may cause clogging of the hair follicles and induce acne.
