Yes, wrinkles are definitely caused by UV rays...
We covered the integumentary system in anatomy class a couple of weeks ago, and the prof had some rather interesting pictures to show us; one was of a Native American woman, about sixty, who'd spent most of her life outdoors; she had deep, numerous wrinkles. Another picture was of a Japanese monk who'd spent most of his life indoors--he was ninety and had just barely started to get crow's-feet around his eyes. It's sun damage that causes wrinkles, UV rays to be specific. Age will decrease the skin's ability to heal itself but it won't actually cause wrinkles.
Aspies probably do spend more time indoors than most. A daily thirty-minute walk outdoors won't cause a great deal of UV exposure, especially if you use sunscreen and wear sunglasses--which I gather that many of us do, since sunburns bother you more if you are touch-sensitive and the sun dazzles you more if you're light-sensitive. We're probably less likely to have outdoor jobs, and more likely to have indoor leisure activities.
I bet we have much less skin cancer than NTs, too.
