Vitamin A regulates the growth of epithelial tissue cells and maintains the normal morphology and function of epithelial tissue. Keep it moist, prevent mucosal dryness and keratinization, and be less susceptible to bacterial damage, which helps to treat acne, pustules, boils, surface ulcers, etc.**; Helps to remove age spots; It can maintain the health of the surface layer of tissues or organs.
Vitamins are a class of organic compounds that are necessary for the maintenance of good health. This kind of substance can neither be the raw material that constitutes the body's tissues nor the ** of energy in the body, but a class of regulatory substances that play an important role in the metabolism of substances. <>
Vitamins are a huge family, and there are dozens of vitamins known at this stage, which can be roughly divided into two categories: fat-soluble and water-soluble. Some substances are chemically similar to a certain vitamin and can be converted into vitamins through a simple metabolic reaction, such substances are called provitamins, such as - carotene can be converted into vitamin A; 7-dehydrocholesterol can be converted to vitamin D3; However, it takes many complex metabolic reactions to form. Tryptophan of niacinin cannot be called provitamin.
Lack of vitamin A will reduce the function of epithelial cells, resulting in decreased elasticity, dryness, roughness, and tarnishing.
Vitamins are essential organic compounds in the body's metabolism. The human body is like an extremely complex chemical factory, constantly undergoing various biochemical reactions. The reaction is closely related to the catalytic action of enzymes.
For an enzyme to be active, it must have a coenzyme involved. Many vitamins are known to be coenzymes of enzymes or components of coenzymes. Therefore, vitamins are important substances for maintaining and regulating the normal metabolism of the body.
It can be considered that the best vitamins are in the form of "biologically active substances", which are present in the tissues of the human body.

Vitamin E is often used in creams and lotions because it is believed to promote healing and reduce scarring after injuries such as burns. The most effective vitamin E to help the body fight oxidants and free radicals is tocopherol (alpha-tocopherol).
There are three types of coarse scores:
Natural vitamin E (d-tocopherol).
Semi-artificial vitamin E: d-tocopheryl acetate, d-tocopheryl succinate.
Man-made synthetic vitamin E: DL-tocopherol, DL-tocopheryl acetate (one D-tocopherol molecule synthesized with one L-tocopherol molecule).
Vitamin E supplements can be divided into 6 main categories:
1) Artificial (synthetic) vitamin E, "DL-tocopherol", as an acetate ester, is the cheapest and most often sold as a nutritional supplement.
2) Semi-artificial "natural**" vitamin E esters, made of"Naturally**"Processed into pills, pills and a nutritional supplement with multiple vitamins.
3) Highly refined natural D-tocopherol.
4) Low-grade natural blend of several types of vitamin E
5) High Gamma Vitamin E Nutritional Supplement Pills.
6) Tocotrienol nutritional supplements.
Tocopheryl niacin and tocopheryl linoleate for cosmetics and some pharmaceutical uses.
In healthy humans, semi-artificial vitamin E can be de-esterified mainly in the liver within a few days, but premature infants, elderly or unwell patients cannot de-esterify artificial and semi-artificial vitamin E.
Functionally as an antioxidant, vitamin E helps to prevent the oxidation of polyunsaturated fatty acids and phospholipids, thus maintaining the integrity of cell membranes.
It protects vitamin A from oxidative damage and enhances its action.
Vitamin E and iodine compounds have been shown to prevent the onset of symptoms associated with vitamin E deficiency.
Prevents the increase of lipid peroxide in the blood.
Some studies have shown a link between cancer prevention and anti-aging, but this has not been widely proven.
Prevents excessive aggregation of platelets.
Enhance red blood cell membrane stabilization and red blood cell synthesis.
Reduces the effects caused by air pollution, which in turn reduces lung damage.
Maintain cellular respiration.
Reduces the deposition of age spots.
Oral vitamin B1, which is metabolized in the human body and excreted from the sweat glands, emits a special smell that mosquitoes flee for fear of this smell.
