Over time, the sun‚Äôs ultraviolet (UV) light damages the fibers in the skin called elastin. The breakdown of these fibers causes the skin to lose its ability to snap back after stretching. As a result, wrinkles form. Gravity also is at work, pulling at the skin and causing it to sag, most noticeably on the face, neck, and upper arms.
Dermatologists also recommend protecting your skin from the harmful rays of the sun by applying sunscreen daily. This ritual is just as important to maintain in the wintertime as it is during the scalding hot days of August. Some daily moisturizers already include a sunscreen component, but you may require stronger protection. Everyone should protect themselves with at least an SPF 15. There are a variety of facial sunscreens on the market, ranging from water-resistant to fragrance-free to vitamin-enriched to self-tanning.
