Smoking causes premature aging

Tar and cigarette smoke deprive the skin of useful oxygen and nutrients necessary for fine health. Avoid smoking and face wrinkles will bother you less.

In addition to the cumulative effects that some of the chemicals have on the skin,
another reason for the extra wrinkles is the way a person holds their mouth when they smoke. Lines are created as a person wraps their lips around the cigarette, and then blows out the smoke. Other contributing factors: squinting and frowning from the smoke. Since the mid-nineteenth century, physicians have noticed that chronic smokers’ skin tends to be think, yellowish, and wrinkled. Hence, smoking has a tendency to make a person look older than their chronological age.
