Love of beauty is human nature, especially young and fashionable women, more like to make themselves more colorful. However, according to relevant statistics, in Europe and the United States developed countries, some love heavy makeup women, deeply poisoned by cosmetics does not account for a minority. If you are not a star, two did not engage in show business, or suggest that you make up light appropriate, and every day to minimize the number of makeup. Some civilian women in order to make their face “beautiful”, coated with a thick powder, cream, and even the actors with makeup oil are used, face coated with white and green. In fact, this powder is not only not beautiful, and there are a number of harmful effects: the first harm: the damage to the normal face of the white and red UV rays, although harmful to the human body, but there are also benefits. How to get a white and red face? In addition to the development, nutrition, the influence of the human race, the sun’s ultraviolet light also plays a big role. Human skin is a very large organ, its area is 1.5 to 2.0 square meters, the face of the skin accounts for 3.5% of the human skin, its face area of 52.5 to 70 square centimeters. The difference between this small place and other skin is that the cold winter is also exposed to sunlight, and thus it is biased by ultraviolet radiation, giving it the color of white and red real beauty. Ultraviolet rays have a erythematous effect on the face, it makes the face become very soft, shiny and elastic. Prolonged exposure to the sun, the face can appear vasodilatation, congestion and the formation of erythema, this ultraviolet erythema also has an anti-inflammatory, anti-neuralgia, anti-allergy, as well as to improve the nutritional status of the skin of the face of the efficacy. According to statistics, when the environment per cubic meter of air containing dust 0.1 milligrams, ultraviolet light can be reduced by one-half, containing 1 milligrams when reduced by two-thirds. Imagine, if the face using grease cosmetics, and then coated with a layer of thick powder, the sun’s ultraviolet rays can not be absorbed. The second harm: detrimental to the synthesis of vitamin D Vitamin D and calcium, phosphorus metabolism is closely related. Its main role is to promote the absorption of calcium and phosphorus in the small intestine, and to promote the absorption of minerals in the bones, it also plays a direct role in the process of calcification. Vitamin D deficiency in adults can lead to osteomalacia. This is when the bones gradually become thinner, which in women can produce a characteristic deformation of the pelvis, resulting in a woman’s inability to give birth normally. The source of vitamin D in the human body, in addition to diet and normal absorption, is biosynthesis, which is of greater significance than absorption from food. In the skin there are components of vitamin D and vitamin D proteins. Vitamin D proto, or 7-dehydrocholesterol, is found in the epidermis. It is converted to vitamin D by the action of ultraviolet light and is sent into the bloodstream. Therefore, not only the face should not apply too much makeup, is the neck should not apply too much cream, otherwise it will affect the body’s production of vitamin D, hindering health. The third harm: the source of “prickly heat” There are many sweat holes on the face. It is estimated that there are more than 70,000 sweat glands on the face, under normal circumstances, the daily sweat through it about 24 milliliters, if the climate is hot, it is doubled to discharge. The face is also rich in sebaceous glands, which often overflow with lipids, especially during puberty, when more sebum is secreted. A heavily made-up face blocks the way for sweat and sebum to get out, and an occasional encounter with Staphylococcus aureus can lead to prickly heat boils. This disease is also known as pseudo-boils or “prickly heat”. At the onset of the disease, a large number of hard, pea-sized to chestnut-sized nodules appear on the face, which develop from red to purple, and discharge yellowish-green, thick pus when they burst, leaving scars when they are cured. Sometimes new boils grow when the old ones subside. In case of improper treatment, sepsis can also occur. No matter how advanced and famous the cosmetics you use, if your usual makeup is often heavy, it will have an extremely negative effect on your skin. Even if you are to attract the attention of the opposite sex, it is also recommended that you do not wear heavy makeup, because the Japanese Shiseido company has made a special survey on this phenomenon, the results show that the vast majority of men want women to wear light makeup. Therefore, I advise beautiful girls, please do not use your face as a color palette.
