Put your hand out next to your face and see if the skin of your hand is better or the skin of your face is better. If the facial skin is good, it means that the skin care products you choose are not bad; If your hand skin is good, there are still some problems with the skin care products you choose.
First of all, what are your criteria for choosing skin care products? Some people say that you can buy more by watching advertisements; Some people say, look at a star, which star you like, and buy the brand she endorses; Some people say that they use famous brands, so they have grades; Some people say that my friend introduced me, and I will use it if she uses it well. However, few brands are used well, and few people have not changed their brands! Why? The effect is not obvious. In fact, most of us, no matter what brand we choose, ignore a very important selection criterion-ingredients. Skin care products are used on your face, your body, penetrate into your skin and be absorbed by your body. What really matters is the ingredients, not something that can be put on your face just by saying hello. Why skin problems, such as dull complexion, long spots, acne, grease particles, etc. Most of them happen to women, while men don't wipe anything but their skin is better than women? Ingredients! It is because women use a lot of skin care products with unknown ingredients that they become international famous brand faces.
In fact, more than 95% of skin care products on the market contain soap alkali, alcohol, mineral oil, fluorescent agent and boride, whether it is a few dollars' treasure or a few hundred dollars' Shiseido. These five ingredients are carriers of skin care products, and no matter what beneficial ingredients the company adds to the products, they are only auxiliary ingredients of these five ingredients. Soap base is usually used for cleaning products, alcohol is usually used for toner, mineral oil is usually used for essence, fluorescent agent is usually used for makeup, and boride is a useless filler. Then, what are the functions of these five ingredients and whether they can effectively maintain our skin, which leads to today's theme-the concept of skin care.
Second, the concept of skin care
Why should we maintain it? With the growth of years, our skin will be dehydrated and aging. Water shortage is the most serious problem of our aging. Without water, our skin will age, and in the process of aging, there will be water shortage, so our skin needs maintenance. People's skin begins to lack water after 10- 12 years old, so the sooner you maintain your skin, the better. If you do nothing but do one thing, that is moisturizing. Water retention is the most basic requirement, so the main purpose of almost all skin care products is water retention, and almost nothing else is done. Then again, if you keep water well, your skin must be very good. It's easier said than done. Lack of water in the skin is not as simple as drinking more water, because the skin will constantly evaporate water, and the evaporation speed has a great relationship with your body temperature, exercise, mood, room temperature and humidity. Most of the water supplement comes from the body and is sent to the surface of your skin through capillaries. Why is there a shortage of water during aging? In other words, if the evaporated water is not replenished quickly enough, you will be more and more short of water.
In order to preserve water, it is recommended not to let water evaporate. At the beginning of the 20th century, a breakthrough in skin care products was the discovery of this point. If some of the lost water is washed back, the skin will become very good. From the beginning, oil was found to be the best water-retaining agent, and mineral oil was found to be the best. The so-called "moisturizing factor" of commercial products is mineral oil. Mineral oil is neutral, does not irritate the skin, has no chemical effect and is cheap. It has been a century now, and all skin care in the cosmetics industry is mainly mineral oil. The reason is not that I don't know what good things can be replaced, but that mineral oil is really cheap and very stable. What are the hazards of mineral oil? To give a simple example: if the skin is burned, everyone knows that the wound should not be oiled. After oiling, the wound heals slowly, bacteria are easy to breed, and the scar is serious. Oil and skin are absolutely opposite. Similarly, when we put mineral oil on our face, our pores and sweat glands are immediately blocked. What we want to seal is water, not sweat. If you put oil on it, both of them will be blocked back. These two things not only block back, but also your skin will secrete some oil that needs to be excreted. Mineral oil will be blocked back, and if it is sealed, it will hide evil people and shelter evil people. Besides, your skin needs to breathe. After using oil, breathing becomes suffocation, and pores struggle to breathe and become larger. Also, mineral oil is sticky and easy to absorb dirt such as dust. Internal and external attack, the secretions inside can't come out, and the dirty things stuck outside are very bad, so it must be thoroughly cleaned, and the oil can be washed off with strong corrosive things. Therefore, the skin care products of cosmetic companies must be oily, and their detergent must be very strong. What can clean the oil most thoroughly? Therefore, most soaps and facial cleansers are alkaline. Is the disadvantage over? No, after the oil is applied, the oil will penetrate into it, which is secondary. Skin excreta can't get out, and if it accumulates more, pores will be blocked, which will produce a hotbed of bacteria. When bacteria spread, acne will grow. In order to prevent acne, after you wash your face with oily things, there must be antibacterial agents in skin care products, such as alcohol. It is very antibacterial, which is not good for your skin, but it has many disadvantages. What tricks are you playing on your skin? Hurt it with all kinds of things, embellish it, just because you start to use oil, take a wrong step and never look back, and it will become more and more vicious.
95% of skin care products on the market are mainly mineral oil, and 95% of cleaning products have alkaline pH values. Because mineral oil seals the skin, water will not leak out, which produces the concept of passive moisturizing. Disadvantages of mineral oil sealing the skin: ① the skin can't breathe and metabolize normally, dirty things can't be discharged, and the water outside can't be absorbed; (2) Mineral oil has strong adsorption capacity and is easy to adsorb dust and dirt in the air; ③ The skin is oily, sebaceous glands hibernate, and the ability of sebaceous glands to secrete oil decreases. It is necessary to clean the skin with strong alkali. The disadvantages of strong alkali are: ① it destroys the sebum membrane of the skin, which is a weakly acidic protective film composed of sweat glands and sebaceous glands secretions, protecting the skin from bacteria and ultraviolet rays; ② The skin is alkaline, which provides a good growth environment for bacteria. After cleaning the skin with strong alkali, the skin will be very dry without the protection of sebum membrane. At this time, people usually put on oily skin care products; The more dirt the oil adsorbs, the stronger the alkali is needed for cleaning. In the long run, the vicious circle, the skin can not be fundamentally improved. That's why the more skin you use, the more problems you have.
