It is crazy not to use sunscreen every day for both health and cosmetic reasons. Even on a cloudy day ultraviolet rays reach the ground. As the ozone layer fails, even more of these harmful ultraviolet rays (UVA and UVB) are reaching the Earth’s surface.
The UVA rays damage the skin and cause premature aging. The UVB rays are responsible for sunburns and skin cancers. You need protection from both. The damage is cumulative. Every time you go into the sun the skin is exposed to ultraviolet radiation and more damage occurs.
The best sunscreens are effective against both UVA radiation and UVB radiation. The best sunscreens also contain compounds that both physically block the UV rays and absorb any UV rays that get past the blocking ingredient. The best sunscreens should not contain PABA and Fragrances that can irritate the skin. Discuss this with your physician or nurse to make sure you’re using the sunscreen that’s best for you.
