Your skin is the largest organ on your body, made up of several different components, including water, protein, lipids, and different minerals and chemicals.

A "healthy" tan is anything but. Tanning is a sign of skin damage, evidence that the sun's ultraviolet rays have penetrated and damaged the skin's support structure. Most wrinkles are caused by sun exposure throughout life -- and it's never too late to halt the process.
What you can do: Wear sunscreen with sun protection factor (SPF) of at least 15. The hands and face are particularly vulnerable to sun damage, due to their frequent exposure. Make sunscreen application part of your out-the-door routine.
Another Top Cause of Wrinkles: Smoking
Beyond question, smoking is bad for your skin. Smoking accelerates the aging process, wrinkling skin and making you look old beyond your years.
Early wrinkling is visible under a microscope in smokers as young as 20. The more years and packs smoked, the more likely wrinkles will occur. Wrinkles are also more likely to be deeper in smokers. Tobacco smoke gives skin an unhealthy color and coarse texture, as well.
What you can do: Stop smoking! Effective tools are available at WebMD and throughout the Internet. Search for "quit smoking."
How Facial Muscle Contractions Cause Wrinkles
Wrinkles at the corners of the eyes (crow's feet) or between the eyebrows (frown lines) are thought to be caused by small muscle contractions. Over a lifetime, habitual facial expressions like frowning, smiling, or squinting leave their mark on our skin.
What you can do: Wear sunglasses or corrective lenses to avoid squinting from the sun or nearsightedness. If the furrowed-brow glare is a regular part of your facial repertoire, trade it in for a more Zen-monk-like gaze.
How Sleeping Positions May Cause Wrinkles
The way you sleep may actually cause wrinkles. No matter how soft your pillow, it puts pressure on your face each night. Over years, this can etch lines into your chin, cheeks, or forehead. Your personal pattern of sleep lines depends on how you tend to rest your face on the pillow.
What you can do: Sleep on your back. People who don't sleep with their face on a pillow do not tend to develop sleep lines.
