Study Proves Sunscreen Prevents Aging
Finally, a four and a half year study of 900 Caucasians aged 25 to 55 in Australia proves that daily sunscreen use prevents aging of the skin. For those of us who see patients every day, this was no surprise, as dermatologists are familiar with the ravages of chronic UV exposure on the quality of the skin. And, we have seen case reports of dramatically different appearances of the facial skin in twins raised with or without chronic sun exposure over their lifetimes. But it will be good to be able to tell our patients now that there is proof that wearing sunscreen every day will not only decrease the risk of skin cancer, but also the signs of aging such as wrinkles and sagging.
