A healthy and beautiful skin must be the dream of every beauty lover, you may have tried a variety of strange skin care methods, but the results are not so satisfactory, today to share with you some of my skin care secrets. Proper daily skin care is an important way to maintain healthy and beautiful skin. The daily basic care of the skin in general includes three major steps: 1, cleaning 2, moisturizing 3, sun protection Skin cleansing 1, the composition of cleaning products and cleaning principle Cleaning products include a variety of facial cleansers, cleansing foam, cleaning gel, cleansing soap, scrubs and special cleaning products used to remove makeup. The main component of cleansing products is surfactant. There are many types of surfactants. Generally speaking, the stronger the cleansing power, the more harmful the ingredient is to the skin. No matter what kind of cleaning products, they should play a proper role in cleaning, but not to destroy the natural barrier function of the skin, so that the skin maintains the best PH value and the best state for the full absorption of skin care products. 2, the choice and use of cleaning products Currently more advocate a mild cleaning method. The general cleaning water temperature should be 32-35 ℃, too cold water is not clean enough and more stimulating, too hot water will damage the skin’s barrier function, so that the skin dry peeling, resistance to decline, the appearance of fine lines, and stimulate capillary expansion and congestion, resulting in “red blood”. The main measure of gentle cleansing is that after using cleansing products, the skin feels smooth and does not feel taut. If your skin feels tight and astringent every time, you may be over-cleaning. The more foamy the product is, the better it cleanses and is more suitable for people with oily skin. A product with less foam and a milder texture is more suitable for people with dry skin. Products with a gel base have a more refreshing texture and are more suitable for people with acne-prone oily skin. Some leave-on cleansing products are made with very mild surfactants and are available for people with sensitive skin. Oily skin and skin prone to keratin build-up can be massaged regularly with a scrub, but be sure to wait for a batch of fine-grained, gently textured products and do not use them daily; once every 2 weeks is generally recommended. Excessive friction will destroy the stratum corneum and damage the natural barrier function of the skin. Dry skin and sensitive skin should avoid scrubbing type products. Common misconceptions about the role of cleansing products 1, that expensive cleaning products with various efficacy ingredients have better skin care effects. The main role of cleansing products is to cleanse. Short contact time plus will not deliberately promote transdermal absorption, so that the added efficacy of ingredients is often just a concept, and no actual effect. Therefore, the key to choosing cleansing products depends on whether the surfactants are safe enough and whether the cleaning is gentle and effective. 2, acne patients or oily skin frequent cleaning of the skin or the use of too strong cleansers. Oily skin is due to the high secretion of sebaceous glands, it is almost impossible to make the opening of sebaceous glands smooth or wash away the excess oil in the sebaceous glands through ordinary cleaning. Excessive use of cleansing products to wash the face will only destroy the natural barrier function of the skin, aggravate the dryness of the skin, and stimulate the secretion of the sebaceous glands with feedback, causing the skin to produce more oil. Therefore for patients with this type of skin it is still recommended to use gentle cleansing, do not use too much scrubbing and strong alkaline cleansing milk cleansing soap, and pay attention to moisturizing care after cleaning. 3. Use makeup remover oil instead of cleanser, expecting to achieve thorough cleaning. The main function of makeup remover oil is to clean water-resistant makeup or waterproof sunscreen by way of oil dissolving oil. If you use makeup remover oil instead of cleanser, not only is it not effective in cleaning, but it also tends to leave the oils of the makeup remover oil on the skin, leading to acne. So after using makeup remover oil, you should clean it again with cleanser to remove residual emulsions and oils. Skin moisturizing 1, the composition and principle of action of moisturizers Moisturizers are synthetic complexes that simulate the composition and ratio of oil, water and natural moisturizing factors in human skin. The main active ingredients of moisturizers include sealants, hygroscopic agents, hydrophilic substrates and emollients. Different moisturizers are the different ratios of these types of substances. 2, the choice and use of moisturizers The way to determine whether a moisturizer is good or bad is very simple. You just have to try this product on your face or body and the feeling of your skin is the best answer. A good moisturizer can provide a long time moist feeling, and the skin is moist, smooth and elastic after use. Just choose your moisturizer according to your age, gender, skin type, seasonal changes and body parts and use it daily. When daily use of moisturizing skin care products still feel the skin on the dry side, you can carry out enhanced moisturizing treatments, such as using moisturizing masks for compresses, etc., available 1-2 times a week. In addition, drinking more water, maintaining balanced and adequate dietary nutrition, getting enough sleep and good mental state, paying attention to sun protection, etc., all contribute to moist and beautiful skin. Yunnan area, especially our Dali with strong UV rays, dry and windy! The skin needs more moisturizing, such as Chengdu, Shanghai, the woman beautiful, is because there is a natural moisturizing environment! Common misconceptions about moisturizing care 1, oily skin does not need moisturizing. Oil control and hydration are not contradictory in any way. Oil is secreted by the sebaceous glands, while water is an important part of the protective barrier function in the stratum corneum of the skin. 2, suffering from allergic skin disease will not be able to use any skin care products. It is already a stereotype that you should stop using any skin care products when you have an allergic reaction to your skin. Choose moisturizing products with different formulations under the guidance of a dermatologist to promote recovery from skin diseases and to relieve the discomfort of dryness and itching caused by skin diseases. Skin sunscreen 1, the composition and principle of action of sunscreen products Sunscreen products can be divided into physical shading agents, chemical shading agents and biological shading agents. People in Yunnan are easily recognized in the north because of the strong sunlight, are gray-brown and gray-brown, chloasma is also more! So sun protection is more important. (1) physical shading agent: can broad-spectrum protection against UVA and UVB. the main physical shading agents are titanium dioxide, zinc oxide, talc, magnesium oxide, calcium carbonate and white clay, etc.. Compared with chemical shading agents, physical shading agents have the advantages of high safety, good stability, not easy to allergic, etc. I formulated my own sunscreen titanium is this type! (2) chemical shading agents: most of the current market are these products! Experiments show that the sun protection factor of 30 products used correctly can provide adequate protection for the skin, the value is then high just some test data from the laboratory, and can not indicate that the sun protection time can be extended indefinitely. The advantages of chemical sunscreens are light texture, good transparency and easy to apply, but there is a certain degree of irritation, and a few people may be allergic to certain ingredients. (3) Biological sunscreens: they do not have UV absorption capacity per se, but can play an indirect role in sun protection by scavenging or reducing oxidative damage and oxygen radicals generated by UV radiation, thus blocking or slowing tissue damage or promoting after-sun repair. Such as some drugs, vitamins and their derivatives, we give sun dermatitis with drugs belonging to this category! 2, the efficacy of sunscreen products and the use of SPF (Sun Protection Factor), that is, the sun protection index, is a sunscreen cosmetics to protect the skin from sun spots, an efficacy indicator, that is, sunburn erythema index (UVB), so foreign sunscreen has this indicator, they are worried about sunburn is not tanning, perhaps more like tanning some, so some of the imported Sunscreen we do not necessarily apply! PA (Protection Factor of UVA, or PFA), is the protection factor against UVA. It is defined as the ratio of the minimum amount of sustained pigment darkening required to cause dark spots from UV exposure with and without sunscreen products. To determine the SPF or PFA value in the laboratory, the amount of sunscreen applied to the test area is required to be 2 mg/cm² and allowed to dry naturally for at least about 15 minutes. Therefore, it is recommended to apply once 20 minutes before leaving the house and repeat the application when leaving the house. Due to factors such as sweating, wiping and skin absorption, the protective effect of sunscreen products is lost after 2-3 hours of application, and it is best to reapply. UVA is still present on cloudy days and a certain amount of shade protection should also be applied. It is also important to note that sunscreen products should be applied after other skin care is completed. Common misconceptions about the use of sunscreen products 1, sunscreen can replace other light protection measures. Sunscreen should never be used as the only means of photoprotection. Complete photoprotection measures include limiting sunlight exposure, minimizing outdoor exposure between the peak UVB hours of 10am and 4pm; wearing a broad-brimmed hat or umbrella when outside; wearing clothing with photoprotection; wearing shades and applying sunscreen products. 2, the higher the SPF value of sunscreen products, the stronger the protection. Experiments have shown that the sun protection factor of 30 products used correctly can provide adequate protection for the skin, the value is then high laboratory test data, and does not indicate that the sun protection time can be extended indefinitely, so our country in 2005 began to limit the value of sunscreen products SPF said, SPF more than 30 all to SPF30 + to say, to avoid misleading consumers. In addition, it should be noted that the sunscreen products to improve the SPF value at the same time must also improve the protection against UVA. We should try to choose products with high SPF and PA values.
