What does SPF actually stand for? Dermatologists fill us in:
Not wearing sunscreen is also doing your skin anda huge disservice. Long-term exposure to the sun without SPF protection can lead to the breakdown of collagen and elastin—proteins in the skin that are responsible for the youthful, full, and bouncy appearance of healthy, young skin. Sun-damaged skin can trigger wrinkling, sagging, sunspots, freckles, dark pigmentation , enlarged pores, and broken blood vessels, she notes.
While many might reach for sunscreen with chemical blockers—since mineral sunscreens tend to feel heavier during application and leave a white tint,, a dermatologist based in New York City, prefers mineral sunscreens. Physical sunscreens contain mineral ingredients—like titanium dioxide or zinc oxide—and sit on top of the skin to deflect and distribute damaging UVA and UVB rays away from the skin. These sunscreens are safer for the skin , and contain no harmful chemicals.
