Here’s another reason to buy a moisturizer with sunscreen.  New research provides some of the strongest evidence to date that near-daily sunscreen use can slow the aging of your skin.  Ultraviolet rays that spur wrinkles and other signs of aging can quietly build up damage pretty much anytime you’re in the sun – a lunchtime stroll, school recess, walking the dog – and they even penetrate car windows.  Researchers in sunny Australia used a unique study to measure whether sunscreens really do provide more than protection against sunburn.  9-hundred people took part in a study.  Some used sunscreen almost daily.  Others only used it some of the time.  After four and a half years, those who used sunscreen regularly had younger looking hands, with a quarter of them showing less skin aging than those who used sunscreen only some of the time.
