Don’t you need sunscreen if you have fair skin? These sunscreen misunderstandings must be avoided in time!

Even though sunscreen is a “cliche”, there are still many people who don’t think so, and even fall into some “traps” of sunscreen. Come and see if you have been “trapped” by these cognitive misunderstandings? < / P > < p > many people think that people with fair skin are not easy to tan, even if they are sunburnt, they are easy to turn white, so they don’t need sunscreen. This statement is wrong. Experts point out that the whiter the skin, the more attention should be paid to sunscreen. Because people with light skin are more sensitive to light and are more likely to get sunburn, yellow people are less likely to suffer from skin cancer than white people. < / P > < p > many people believe that as long as you stay indoors, you don’t need sun protection. Studies have shown that glass can block ultraviolet B, but not ultraviolet a. As long as the sun shines on the skin through the glass for more than 10 minutes, it will also burn the skin. In addition, ultraviolet rays can be refracted through the air, causing damage to the skin from different angles. < / P > < p > the sunscreen effect is related to the amount of sunscreen applied and the frequency of application. The sunscreen can’t last for a whole day. Sweating can easily wash off the sunscreen, so it needs to be applied every 2-3 hours. If it is continuous exposure in the hot sun, it should be reapplied after 60-90 minutes to ensure the sunscreen effect. In addition to the face, other exposed such as the neck, arms, ears, etc. should also be coated with sunscreen. The lower lip is vulnerable to sunlight. Use lipstick with sunscreen. UVR is easy to cause hair dry and rough, lose elasticity and luster, can use sunscreen mousse. < / P > < p > in addition, the biggest mistake of sunscreen use is not enough. The British Association of dermatologists recommended that the amount of product applied to the whole body should be 1 cent. For the whole body, at least 30 ml of sunscreen should be applied, including 5 ml for each leg, 5 ml for the front chest and back, 5 ml for both arms, and 5 ml for the neck and face. < p > < p > sun exposure can supplement vitamin D and promote calcium absorption, so many people do not want to sunscreen. However, daily exposure to the sun for a short period of time is enough for our body to absorb calcium. Special groups such as the elderly with high incidence of osteoporosis can receive appropriate sunlight, but still need reasonable sun protection, which can slow down skin aging and prevent the occurrence of skin cancer.
