Puffing cigarettes regularly is not only bad for your health but it also can dramatically alter your facial appearance.
Citing researchers from the Department of Plastic Surgery at Case Western Reserve University study of physical differences between identical twins who smoked and nonsmokers, CNN story confirmed long-held belief that smoking does age you.
The researchers studied 79 sets of twins between the ages of 18 and 78 at the annual August gathering of twins in Twinsburg, Ohio.
A professional photographer took the twins picture which later divided into two categories. First group 45-sets of twins – one smoked the other didn’t.
Second group was made up of smokers, but in each set, one twin had smoked at least five years longer than the other.
The photos were examined by two doctors, a medical student and assigned scores to their facial features.
The findings – in the case of the first group, the researchers said the smoking twin appeared older 57% of the time.
For the second set, the longer-smoking twin looked older more than 63% of the time, meaning the aging differences could set in after just five years.
“This study confirms some of what was believed in the most scientific way possible,” CNN reports, quoting lead researcher Dr. Bahman Guyuron.
Dr Bahman Guyuron said with longer follow-up, they believe that every smoking twin might have exhibited a difference in aging.
The study looked at other aging factors — alcohol consumption, stress and sunscreen use, for instance — and found they were similar in these sets of twins.
However it didn’t address changes in the twins’ living environment or diet.
“Smoking reduces the collagen formation, results in collagen degradation and reduces the skin circulation,” Guyuron said.
“Additionally, nicotine reduces the skin thickness. All of these reduce skin elasticity and (cause) premature aging.”
The study was published in the journal Plastic and Reconstructive Surgery.
