1. Protect yourself from the sun

The best way to take care of your skin is to protect it from the sun.
Ultraviolet light the invisible but intense rays of the sun damages your skin, causing deep wrinkles, dry, rough skin, liver spots, and more serious disorders, such as noncancerous (benign) and cancerous (malignant) skin tumors.
For the most complete sun protection, use all three of these methods:

Avoid the sun during high-intensity hours. The sun's rays are most damaging from 10 a.m. to 4 p.m. Reduce the time you spend outdoors during these hours.

Wear protective clothing. Cover your skin with clothing, such as long-sleeved shirts, long pants and wide-brimmed hats. Also, keep in mind that certain clothing styles and fabrics offer better protection from the sun than do others. For example, long-sleeved shirts offer better protection than short-sleeved shirts do. And tightly woven fabrics such as denim are better than loosely woven fabrics such as knits.

Use sunscreen. Apply sunscreen liberally 20 minutes before going outdoors and reapply every two hours, after heavy sweating or after being in water.
2. Don't smoke
Smoking can accelerate the normal aging process of your skin, contributing to wrinkles. Skin changes from smoking can be seen in young adults who have been smoking for as few as 10 years.

Smoking causes narrowing of the blood vessels in the outermost layers of skin. This decreases blood flow, depleting the skin of oxygen and nutrients, such as vitamin A, that are important to skin health. All of these factors increase damage to the elastic fibers (elastin) and collagen which give your skin strength and elasticity.

In addition, the repetitive facial expressions you make when smoking such as pursing your lips when inhaling and squinting your eyes to keep out smoke may contribute to wrinkles. It's also possible that repeated exposure to the heat from burning cigarettes may damage your facial skin over time.
