1. What's your take on sun exposure and absorbing vitamin D? Is it wise to spend a little time in the sun without SPF?
A little exposure is okay with SPF — we all need some sun in small doses for vitamin D. That doesn't mean to sunbathe, but rather a few rays that you get while you're wearing SPF 15 or higher. They key is to never burn — and remember, tanning is the number-one ager of the skin!
