This Is What 7 Smoker vs. Non-Smoker Identical Twins Look Like After Years Of Smoking

Researchers at Case Western University’s Departments of Plastic Surgery and Otolaryngology set out to identify the effects of cigarette smoking on facial aging. To do so, they compared standardized photos of identical twins with different smoking histories. Their results reveal the differences in the faces of smoking and nonsmoking twins. It makes you wonder what the differences in their hearts and lungs might look like as well:

The twin on the left has smoked 17 years longer than the twin on the right. Note the differences in lower lid bags and upper and lower lip wrinkles.

Both twins are smokers. The twin on the right smoked 14 years longer than his brother.

The twin on the left is a non-smoker and the twin on the right smoked for 29 years. Note the differences in peri orbital (i.e. the eyelid or skin around the eye) aging.

The twin on the right side is a smoker; the twin on the left is a non-smoker. Notice the differences in the nasolabial creases (i.e. the lines running from the side of the nose to the sides of the lips).

The one on the left is a smoker. Definitely has a lot more wrinkles than the non-smoker.

The twin on the right is the smoker. Notice the lines around her lips along with the skin under her eyes.

From 2007 to 2010, researchers led by plastic surgeon Bahman Guyuron recruited a total of 79 pairs of twins, all of them attendees of the annual Twins Days Festival in Twinsburg, Ohio. Importantly, Guyuron and his team only recruited pairs in which one twin either smoked, or had smoked a minimum of five years longer than his or her sibling. Twins were photographed by professional photographers, and their photos were later analyzed by a panel of blinded judges, who graded wrinkles and ranked age-related facial features according to standardized scales.
