Secondly, when applying vitamin E to your face, you should also pay attention to basic moisturizing care, such as using toner and lotion first, and then using vitamin E, because the proportion of oil is light, the proportion of water is heavy, and the oil floats on the water surface, which is more moisturizing and can also treat dryness. The face painted with VE will not turn black. Some people think that people turn black because oil has dust, even if it is used at night, the dust is less than during the day. So if you don't use some cream or powder cake after using VE, it will look dusty and feel very dark.
VE (vitamin E), also known as tocopherol or pregnancy-induced phenol, exists in edible oil, fruits, vegetables and grains. 1938 was successfully synthesized, and now there are tablets, injections, suppositories and other dosage forms.
Alias: tocopherol or anti-infertility vitamin

Vitamin E, also known as tocopherol, is a fat-soluble organic compound. Eight known compounds have similar physiological functions, four of which are more important. V-E refers to α-tocopherol.
The most prominent chemical property of vitamin E is antioxidation, which can enhance the antioxidant capacity of cells and maintain the integrity of various cell membranes. Participate in various metabolic processes of some cells and tissues in the whole; Maintain the activity and receptor of membrane-bound enzyme. Some people think that vitamin E has many important physiological functions. For example: anti-aging, anti-coagulation, enhancing immunity, improving peripheral blood circulation, preventing arteriosclerosis, and maintaining the integrity of red blood cells, white blood cells, brain cells and epithelial cells, thus maintaining the normal functions of muscles, neurovascular and hematopoietic systems. It is also found that vitamin E has physiological effects similar to ginseng, such as protecting gastric ulcer; Can promote the synthesis of DNA and protein; Prolong the life of red blood cells; Enhance disease-free activities; Delaying the aging of blood vessels and tissues remains to be studied.
Long-term lack of vitamin E can lead to giant cell hemolytic anemia, and the content of vitamin E in patients' blood decreases. The dietary supply of vitamin E is not stipulated in China, but it is stipulated in the United States as 12 ~ 15 international units per person per day.
Functional purpose
It has antioxidant effect. It can enhance skin capillary resistance, maintain normal permeability, improve blood circulation, regulate fertility function and resist aging. Used for coronary heart disease, arteriosclerosis, habitual abortion, muscular dystrophy, muscle spasm, scleredema neonatorum, lupus erythematosus, dermatomyositis, scleroderma, nodular vasculitis, etc.
Dosage form: capsule: 5mg,10mg,100mg. Injection: each tablet 1 ml contains 5mg and 50mg.
Note: Not suitable for use with sucralfate and mineral oil. In over-the-counter drugs, rubber pills are used.
Properties and stability: Vitamin E is a light yellow transparent viscous liquid; It is odorless, turns black when exposed to light, is sensitive to oxygen and is easy to be oxidized, so it can protect other oxidizable substances (such as unsaturated fatty acids and vitamin A) in the body, and will slowly oxidize and deteriorate when exposed to air or ultraviolet rays.
Drug action:
(1) Anti-free radical: Free radical is an active group widely existing in various chemical reactions and plays an important role in normal physiological metabolism of human body. If excessive free radicals lead to free radical chain reaction, it will lead to lipid peroxidation of unsaturated fatty acids in cell membrane, and a large number of newly generated lipid peroxides will damage protein and nucleic acids in cell membrane and cells, which will cause damage to the body. The anti-free radical effect of vitamin E is due to the fact that the free radical itself is a derivative of benzopyran, the benzene ring has active hydroxyl, which is reducing, and then there is saturated side chain on the five-carbon ring, which determines that vitamin E is reducing and lipophilic. When free radicals enter the lipid phase and have a chain reaction, vitamin E plays a role in capturing free radicals. Vitamin e has a highly effective anti-free radical lipid peroxidation effect.
(2) Vitamin E and anti-aging: It has been studied for decades, and there are different opinions. Generally speaking, vitamin E has little effect on the longest life span of population aging, but it can prolong the average life span, so the anti-aging effect of vitamin E is only a health care function.
(3) Vitamin E and immunity: the lack of vitamin E has an impact on the immune function of human beings or animals, which not only reduces the body immunity, but also has a great impact on the cellular immunity.
(4) Vitamin E and cardiovascular diseases: A large intake of vitamin E can reduce the incidence of atherosclerosis, which may be related to the fact that vitamin E can hinder the "foaming" of arterial endothelial cells and balance the cholesterol metabolism of endothelial cells.
(5) Study on vitamin E and liver: In 1980s, it was clarified that vitamin E was one of the important protective factors for hepatocyte growth. American scholars have found that one of the last ways of liver cell death is the depletion of vitamin E in liver cells, and its mechanism is different from that of calcium ion, but it uses the form of phase itself in cells to play its role as a cytoprotective factor. Vitamin E has protective effect on acute liver injury and chronic liver fiber. Wake up, crane?
(6) Vitamin E and skin: Vitamin E itself is a good antioxidant, which can enter skin cells and has a chain reaction against free radicals. It is superior to SOD in theory and can be used to prevent skin keratinization.
