1, fair-skinned people. The fairer the skin is, the more people should pay extra attention to sun protection. This is because light-skinned people are more sensitive to light and more prone to sunburn, which is one of the factors why yellow people are slightly less likely to develop skin cancer than white people. 2. Children and teenagers. Children are the most sensitive to ultraviolet rays because their skin and eye tissues are more fragile, plus they spend more time outdoors and are exposed to the sun more than twice as much as adults, so it is more important to do a good job in sun protection. Studies show that although skin cancer mostly develops in middle age, the majority of UV damage in a person’s lifetime occurs before the age of 18. The study points out that the risk of melanoma will increase by 80% if there are five or more sunburn blisters during the age of 15 to 20. 3. People who are prone to sunburn redness. If you find yourself prone to peeling, redness, blisters and other problems once exposed to the sun, it means you may be photosensitive and need to strengthen your sun protection. 4. People who wear contact lenses. From the point of view of disease, people suffering from acne, dermatitis, keratitis, and those who wear contact lenses should pay extra attention to sun protection. 5, outdoor workers. People who spend a lot of time outdoors, such as traffic police, construction workers, welders, farmers or drivers, etc., are naturally more exposed to UV rays. Especially stay in the mountains, the seabed, the water, the beach, concrete buildings or snow, etc., vulnerable to reflected ultraviolet light, to pay special attention. 6, people who take antihypertensive drugs. European and American research reports found that taking antibiotics, diuretics, non-steroidal anti-inflammatory painkillers, oral contraceptives, antihypertensive drugs, etc., will also make the skin more sensitive to light.
