So many people are still walking around without SPF and, it's quite scary! At first, I thought it was because people didn't know how dangerous UV rays are to our skin. Then I pondered, people think SPF is only for seasonal use (only in the summer or outdoors etc). If they knew that 85% of extrinsic aging happens because of exposure to the UV rays, they would run to the nearest store to buy SPF! Suppose they knew that wrinkles, fine lines, and sagging skin can be caused by not wearing SPF. The collagen and elastin that gives our skin its strength and elasticity can be severely damaged if people don't wear SPF. I should let them know. SPF PLEASE!
