2. Don't smoke

Smoking makes skin look older and plays a part in wrinkles forming. Smoking narrows the tiny blood vessels in the outermost layers of skin. This lessens blood flow and makes skin duller. It also depletes the skin of oxygen and nutrients that are key for skin health.

Smoking damages fibers called collagen and elastin that give skin strength and suppleness. What's more, the facial expressions that people make over and over while smoking can play a role in wrinkles. These expressions include pursing the lips when breathing smoke in and squinting the eyes to keep out smoke.

Smoking also raises the risk of squamous cell skin cancer, especially on the lips. If you smoke, the best way to protect your skin is to quit. Ask your healthcare professional for tips or treatments to help you stop smoking.
