The skin is a mirror of human health and beauty. However, human skin starts to age naturally after the age of 25, and the normal health of the skin can be affected by the external environment, skin diseases, inappropriate cosmetics, and internal diseases, which can affect the brightness of this mirror. At present, there are different grades and a wide range of cosmetics in major shopping malls, and large and small skin beauty salons can be seen in the streets and alleys. However, the blind pursuit of health and beauty has to a certain extent caused disorder in the skin care market and unscientific skin care methods: Unscientific skin care methods are manifested in the following ways: 1, cosmetics contain chemical ingredients that damage the skin: some of the cosmetics on the market contain fragrance (to increase the need for fragrance), preservatives (to extend the shelf life of the need), pigments (to color eye-catching (for colorfulness), hormones (for anti-allergic needs), and so on. These chemical-containing skin care products can cause chronic damage to the skin to varying degrees, especially hormone-containing cosmetics will produce hormone-dependent dermatitis with long-term use, that is, the human skin must rely on this hormone-containing cosmetics every day, if you stop using the skin will appear red, itchy, burning sensation, if you do not stop using the skin over time will appear thinning, aging and capillary dilation, so that consumers To the cosmetics can not stop, but continue to use and will enter a vicious circle, like a person addicted to drugs. 2, beauticians lack of basic skin specialist knowledge: in our country engaged in skin beauty practitioners, in addition to the hospital medical cosmetic physicians, social “beauticians” do not need any qualification access, regardless of education, regardless of whether they have been professionally trained, as long as they hang the signboard of the beauty salon can operate, which will inevitably mislead This is bound to mislead consumers. Because, not every cosmetic is suitable for everyone, not the most expensive cosmetics is the best cosmetics, especially when some people have skin diseases, some cosmetics may aggravate the original skin disease. 3, cosmetics exaggerated functional efficacy: some cosmetics actually only have a general skin care role, but in the publicity exaggerated its efficacy, such as spot, wrinkle, acne and whitening, etc., the results of the application may not only not achieve the desired effect, but may cause skin damage. What does scientific skincare mean? Scientific skin care means that according to each person’s respective skin characteristics especially whether they have skin diseases, try to choose medical skin care products that are non-irritating, non-allergenic and non-chronic damage to the skin. The skin is a natural barrier of the human body. Not only can many skin diseases destroy this barrier, but inappropriate cosmetics can also destroy this barrier, thus causing many skin problems. The rule of thumb is to maintain and repair the barrier function. An experienced dermatologist can advise you to choose cosmetics with different effects according to different skin conditions. 2. Choose natural cosmetics Natural cosmetics do not contain chemical ingredients such as colors, fragrances, preservatives and hormones. At present, there are two main categories: one is derived from natural plant extracts, such as the Sino-US joint venture Yunnan Dianhong Pharmaceutical production of Winona brand cosmetics, and the other is derived from living water, such as the French Avène brand, such cosmetics are harmless to the skin, and at the same time, many skin diseases and preventive and therapeutic effects, therefore, these cosmetics are also known as medical skin care products. Water can carry a boat, but it can also overturn it! Unsuitable skin care products may be counterproductive, scientific skin care can add brilliance to the mirror of health and beauty to the skin.
