Types Of Sunscreen

When you go out in the sun, you want to make sure that you put on sunscreen. Sunscreen helps protect you from the ultraviolet rays that can cause sunburn. These ultraviolet rays can also increase your risk of developing skin cancer. There are two main types of sunscreen today, chemical blockers and physical blockers.
Chemical blockers work by blocking the absorption of ultraviolet radiation within a specific wavelength.  Most chemical blockers are designed to protect against both UVA and UVB radiation. Physical blockers reflect ultraviolet radiation.  These sunscreens also offer protection against both UVA and UVB radiation. Physical blockers typically last longer than chemical blockers. However, it is easier for physical blockers to be washed off via sweat or water.
When you are buying a sunscreen, it is important for you to pay close attention to the sun protection factor. The sun protection factor, which is better known as the SPF, is a measure of how effective a sunscreen is at protecting you from the sun’s rays. The higher the SPF is, the better. The SPF scale ranges from two to 100. You should make sure that you select a sunscreen that has a SPF of at least 15
