I don't go out in the sun and I still got wrinkles on the back of my neck, though I caught them early. Now I know why I have them. When slouch in my chair and then have to bend my head back to have it level at the screen, my neck bends to make a crease. When I sit up straight, the crease goes away. So, don't slouch, keep your head and body up straight, and you won't get wrinkles on the back of your neck.
The ones on the front of my neck are probably from lying down with a big pillow or couch arm under the back of my head.
