It's been a long time, but we should watch the sun bit by bit. The sun is the main factor leading to skin aging and forming spots on the skin surface. Even in spring, if the skin is exposed to the sun for ten minutes, it will age ten days earlier. Only by doing a good job of sun protection, effectively preventing the production of melanin, not being sunburned or hurt, can we stay young and moist forever. Do you need sun protection in spring? Yes, sun protection must start in spring. Expert research has proved that the ultraviolet rays of sunlight are composed of long-wave UVA, medium-wave UVB and short-wave UVC, and the most penetrating UVA exists around you all year round, whether it is sunny or rainy. It can penetrate epidermis and attack dermis, causing serious damage to collagen and elastin in skin. Over time, it will cause problems such as skin relaxation, wrinkles and microvascular appearance. Facts have proved that although spring is not as hot as summer, ultraviolet radiation is not weaker than summer. This season, the global ozone layer content is the least, so the ultraviolet content increases. In addition, the metabolic cycle of the skin is generally 28 days. After receiving strong ultraviolet radiation in late April and early May, sunburn will appear in June. Therefore, whitening and sun protection should start from spring. How to choose a suitable sunscreen before the arrival of summer to protect delicate skin from the sun is really a top priority for women who love beauty. So, how to choose sunscreen? 1. It is recommended to have an accurate skin test before buying sunscreen. Oily skin should choose water-based sunscreen products with strong penetration; Dry skin should choose cream-like sunscreen products; Generally, there are no strict rules for neutral skin, and lotion sunscreen is suitable for all skin types. 2. calculate SPF value. Generally speaking, the higher the SPF index, the greater the protection. Generally speaking, it is more suitable for people with ordinary skin color to use SPF8 to 12; Those with fair skin are advised to choose SPF30 sunscreen; For people who are allergic to light, the SPF value should be between 12 and 20. 3. Understand the applicable population of different sunscreens. Different sunscreen products have different application targets. The best way is to try it on the inside of your wrist before buying it. If the skin becomes red, swollen, painful and itchy within 10 minutes, you have an allergic reaction to this product. You can try a product with a lower SPF than this one. If there is still a reaction, it is best to give up the brand's sunscreen.

Because the cream can not only isolate ultraviolet rays, but also isolate makeup and dirty air. 3. Ultraviolet radiation not only produces melanin, but also causes skin aging. Therefore, even the fair-skinned MM should use sunscreen products in time every time she basks in the sun, and wipe it again every 2-3 hours. In addition, you will get sunburned in the water, so for those who are interested in swimming or diving, you need to use sunscreen products with high SPF and good waterproof effect every time you go into the water. In order to get better sunscreen effect, it is best to apply sunscreen lotion to all parts of the skin half an hour before going out. When the sun is strong, it is best to wear dark clothes instead of white. White clothes only reflect heat and can't block ultraviolet rays. Black, red and purple cotton-padded jacket are all good choices. 6. In order to avoid skin pigmentation, try to eat less irritating food that is too salty or too spicy; Fluorescent lamps in bars and restaurants contain strong ultraviolet rays, so it is necessary to protect them when going to the above places.
