So think ahead. Be aware that smoking ages your face measurably. It will rob you of your youthful good looks before you are ready to give them up.
Sun exposure is equally, if not more, harmful to your skin. If you limit exposure to the sun and are careful to wear high-SPF sunblock as well as protective clothing, sunglasses, and a hat, you are, in effect, preventing future lines and wrinkles and, quite possibly, skin cancer.
As scientists learn more and more about the sun’s rays, sun-protection products will probably become more sophisticated. We do know that the sun’s long UVA rays are the aging rays, since they go deep into the skin, destroying its support structure of collagen and elastin. The short UVB rays are cancer-causing, and infrared rays are the heat penetrators, which can feel good, but are also responsible for serious damage. Look for the most state-of-the-art sunblocks, which protect from all three types of rays.
Note: Tanning salons are unregulated in this country. Despite claims of safety, tanning beds can be extremely harmful.
