More and more people in modern society are focusing on skin care, and a new phenomenon is that men are also starting to pay attention to skin health and care. The national skin belongs to Phi Type III or IV, not easy to sunburn, but easy to tanning; lighter photoaging, but easy to dull skin tone. Therefore, when choosing skin care products and beauty treatments, you should not just follow European and American trends, but choose scientifically according to your skin type. There are many sources of skin care products, internet, superstores, beauty salons, hospitals, but the principle is the same no matter where you shop from. All skin types should be based on moisturizing because moisturizing is the most important aspect of protecting the skin barrier. Moisturizing does not mean being more oily, but choosing moisturizing ingredients that are easily absorbed by the skin, so that the skin does not feel tight and flaky and is shiny. The second most important protection is sun protection, which is also the most neglected part of the country. We should protect ourselves from the sun 365 days a day, and if exposed to strong sunlight for a long time should also be reapplied, where physical sunscreen is safer and less likely to be allergic. The immediate effect of sunscreen is to prevent or reduce tanning, and the long-term effect is to delay photoaging, such as wrinkles, discoloration and sagging skin. After moisturizing and sunscreening, the application of functional cosmetics such as whitening, spot removal, anti-wrinkle, acne, and allergy relief can be involved. While focusing on efficacy, we should try to avoid skin care products containing heavy metals, hormones and other harmful ingredients, and correct some bad skin care habits, such as excessive washing, high water temperature, too strong acid and alkaline cleansers, excessive friction (e.g. scrubbing, massaging too often), artificial damage (e.g. squeezing pimples, tearing scabs and scratching), frequent cosmetic changes and neglecting trials leading to allergies, etc. For different skin types, different skin problems should be taken into individualized program, not a thousand people. More and more people are undergoing cosmetic laser treatments, but most of these methods are invasive and the treatment itself has the same impact on the clinical outcome as the post-operative care. The appropriate method, parameters and frequency are very specialized techniques, do not choose informal medical institutions for treatment. More care should be taken in post-damage skin care, when the skin is quite fragile and it is particularly important to avoid all unnecessary irritation while choosing functional cosmetics with a specialized restorative nature. In clinical practice, we often see skin conditions caused by improper skin care, and in view of the fact that people in the internet, supermarkets, beauty salons and some informal hospitals are not professional dermatologists and know little about scientific skin care, and some people are even driven by commercial interests to ignore the identification of individual skin types and just push products, we recommend that you go to a regular hospital for consultation. The dermatology department of many public hospitals can provide these services to avoid unnecessary damage to the skin.
