How to prevent skin cancer in summer

It is understood that if you are exposed to the sun for a long time, sunscreen will play a minimal role in preventing skin cancer. The reason for this is that it is not only sun exposure that will cause you to develop various skin cancers. So how can you prevent skin cancer in the hot summer?

Generally speaking, sunscreen is effective in filtering out ultraviolet rays that are harmful to the skin, but many people mistakenly believe that they can stay in the sun longer with the protection of sunscreen. This idea is wrong and will increase the possibility of skin cancer.
Most sunscreens don’t block the UV rays that penetrate deeper into the skin and are more likely to cause wrinkles and skin cancer—even some that claim to block all types of UV rays.
The best sunscreens that can block ultraviolet rays should include ingredients such as zinc oxide and titanium dioxide. In addition, when purchasing sunscreens, consumers should also pay attention to whether they are waterproof and whether the SPF index reaches 30 or even higher. This index reflects the ability to block ultraviolet rays, and consumers should also apply it frequently.
