Those fine lines that appears due to skin aging are what you call wrinkles. Dried out skin because of cold weather exposure may result to big wrinkles. Smiling and frowning constantly in the same position cause the muscles to contract. When this happens, the fiber of the skin that forms elasticity is destroyed. And this is another reason for wrinkles to appear.
The UV light, especially the one that you get from direct exposure to sun, is another reason to get wrinkles. Fortunately, modern medicine has produced many anti wrinkle treatments which offer positive solution to the problem.
