Why Sunscreen is Important in Summer?
📷Why Sunscreen is Important in Summer?
1.1, Prevent aging Compared to other organs of the body, the skin ages very quickly. All cells age with age, which we call "natural aging." The most powerful of the external environmental factors that the skin is exposed to is ultraviolet rays. Therefore, doing a good job of sun protection can effectively prevent skin aging. 1.2. Prevent skin cancer Intense ultraviolet rays block the repair of DNA in skin cells. Skin cells contain enzymes such as endonucleases that can make the broken DNA connect again. If the skin is sunburned or stays in a place with strong ultraviolet rays for a long time, DAN cannot be repaired, but it becomes the cause of skin cancer. 1.3, Prevent pigmentation To resist the damage of ultraviolet rays, the skin will increase melanin growth. After sunbathing, the skin will darken, which is the relationship between black increase. Even if we don't go sunbathing, the sunlight we are exposed to in our lives alone is enough to increase melanin. As a result, our skin produces a variety of freckles, dark spots, and spots.

1. Do not wash your face with hot water after sunbathing In the hot summer, after a day of sun exposure, we all know that cool water can make pores shrink, let the skin cool down, and have a heat-reducing effect. If you use hot water, it will make the blood vessels swell, and sunburn may grow, especially after outdoor exercise. 2. Wear a colored T-shirt to resist the sun The sunscreen ability of clothes depends first on the material of the clothes, followed by the color, for example, the SPF value of cotton clothes is about 15 to 40; The SPF value of polyester light-colored clothes is about 7 to 10; The SPF value of knitted light-colored clothes is about 4 to 9. Therefore, it is best to wear a colorful cotton T-shirt in summer, which has a better filtering effect on ultraviolet rays than white. 3, Do not eat photosensitive vegetables If your skin is more prone to spots, it is best not to eat celery, coriander, white radish, and other "photosensitive" vegetables in the summer, eating these vegetables is easier to make the skin grow good spots.
