Study at twins' convention helps clarify how smoking affects facial aging

Abstract

We all know that smoking is bad influence on human health. Smoking causes many diseases and premature aging. This is best seen in the twins. Study at Twins' Convention Helps Clarify How Smoking Affects Facial Aging. Taking advantage of the annual Twin Days Festival, held in Twinsburg, Ohio, the researchers identified pairs of identical twins who differed by smoking history. In each pair, either one twin smoked and the other did not, or one twin smoked at least five years longer. Scores on several measures of facial aging were significantly worse for the smokers. The smokers had more sagging of the upper eyelids, as well as more bags of the lower eyelids and under the eyes. Twins who smoked also had higher scores for facial wrinkles, including more pronounced nasolabial folds, wrinkling of the upper and lower lips and sagging jowls. Twins with a longer duration of smoking had worse scores for bags on the lower lids and under the eyes and lower lip wrinkles.
