January isn’t exactly peak season for sunscreen shopping, but don’t neglect a quick slather on exposed areas (both for yourself and your children) during the winter. UV rays continue to wreak havoc on your skin even with weaker winter rays — and even through windows. Children are particularly vulnerable in cars, since they often sit down low in the back seat, where side and back windows offer little to no protection. (Front windshields typically block most UVA radiation.)
The bottom line: savvy parents use sunscreen and watch the clock even in pale winter light, just as at any other time of the year.
