What are the common sense of sunscreen that should not be forgotten
1. Adults' melanoma is mostly caused by the sun exposure in childhood. Infants aged 6 months can't take a beach bath. Children before 7 years old should wear T-shirts, sun hats and sunscreen for children. They should not go out from 12 noon to 2 pm in summer.
2. People are exposed to "capital" for about 5000 hours. According to the data, skin cancer can only be caused by 5000 hours of sun exposure in ordinary people, but this time of sun exposure not only refers to the summer sun exposure, but also includes all daily contact with the sun. Therefore, the more times of sun exposure, the more points deducted. When 5000 hours are deducted, it is very dangerous to expose the skin to the sun.
3. Sunburn is not the only damage the sun does to the skin. As we all know, the sun will form spots, wrinkles, skin relaxation, but these are only visible to the naked eye. In fact, it can also cause a certain degree of damage to cells and genes. Some cells are killed on the spot, while some injured cells will release a chemical substance to stimulate capillaries and cause them to rupture, which is commonly referred to as reddening. In particular, UVA can penetrate the skin, make the skin lose elasticity, and even cause skin cancer.
