Which is more sunscreen, an umbrella or a hat?

The ultraviolet rays in the sun are composed of long-wave UVA, medium-wave UVB and short-wave UVC, among which UVA and UVB, which have the strongest penetrating power, are also the biggest culprits for hurting the skin! It can penetrate epidermis and attack dermis, accelerate cell aging, seriously destroy collagen and elastin in skin, lead to the loss of cell self-repair ability, and finally lead to skin relaxation, wrinkles, spots and other problems. There are many methods of sun protection, some will directly apply sunscreen, and some will choose to wear a sun hat or choose a sun umbrella. As for which is more sun-proof, umbrella or hat, it depends on the sun-proof ability and sun-proof area of umbrella and hat. First of all, ordinary hats or umbrellas can't protect against the sun. This is because UVA in ultraviolet rays is very penetrating and can penetrate ordinary umbrellas, glasses and clothes. So if you want to protect yourself from the sun, you must first choose a sun umbrella and a sun hat with sun protection function. When they have the same shading ability at the same time, there is not much difference in shading effect between them. Secondly, we know that the sun protection area of the sun protection hat is not as large as that of the sun protection umbrella, so it is recommended that the sun protection umbrella be used first for living bacteria. In addition, it is necessary to remind friends that the application of sunscreen should be carried out under the premise of using an umbrella or hat for sun protection. Why? Because umbrellas or hats can only cover local skin, the refraction of glass windows can be said to be useless for the reflection of the ground. So even if you go out with a sunshade or a sun hat, remember to wear sunscreen products.
