These types of UV-absorbing and converting ingredients are called chemical filters. For example, the compound named oxybenzone absorbs UV radiation and converts it into heat, which is then released from the skin. “Broad spectrum” sunscreens can work to protect the skin against both UV-A and UV-B rays.Ģ) A sunscreen’s ingredients indicate how the product has been formulated to protect against UV radiation. The public often assumes that they get twice as much protection from SPF 100 sunscreen as from SPF 50- properly applied SPF 50 sunscreen blocks 98 percent of UVB rays SPF 100 blocks 99 percent. They are more likely to use high-SPF products incorrectly resulting in greater exposure to harmful ultraviolet radiation. Research has found that people are misled by the claims on high-SPF (50+) sunscreen bottles. SPF 15 filters out approximately 93 percent of all incoming UV-B rays.Two important characteristics of sunscreen are: 1) the Sun Protection Factor (SPF) and 2) the mechanism used (either chemical filters or mineral filters) to prevent UV radiation absorption into the skin.ġ) SPF is a measure of a sunscreen's ability to prevent UV-B from damaging the skin. Sunscreens are applied to protect the skin from harmful ultraviolet UV radiation. UV-A can increase the carcinogenic (cancer causing) effect of UV-B rays because the cells under the top layer of skin are also damaged and cannot help repair the sunburn above. They are responsible for the wrinkling and leathering of skin. UV-A rays have the longest wavelength of UV radiation, so they penetrate the deepest into the skin. UV-B rays penetrate the top layer of the skin and are primarily responsible for sunburns, which is a big risk factor for skin cancer. There are two different types of UV radiation rays that humans come into contact with on a daily basis: UV-A and UV-B. Therefore, it is important to practice good sun safety for you and your children while outdoors and enjoying the weather. However, part of the sun’s energy is emitted as invisible rays called UV radiation which can burn skin and cause skin cancer. Sunshine provides a boost of mood, vitamin D, and other health benefits. Playing outside is important to children’s health and development, and some of the greatest family or childhood memories arise from outdoor fun-especially fun in the sun. Practice safety in the sun to ensure outdoor fun!
