Some individuals appear older than their actual age. The main causes of this accelerated senescence are often unclear. Through studies on twins, our group and others have identified some of the factors that contribute to premature aging. These include sun exposure, smoking, drinking, weight loss after age 40, weight gain before age 40, and being on antidepressant medications.1 Other studies have also shown repeatedly that smoking is an independent lifestyle factor associated with facial aging,2–4 and there are molecular mechanisms of tobacco on dermal fibroblasts. However, there has been a relative paucity of publications that include facial analysis of smokers to determine what parts are affected the most by smoking. We capitalized on the unique opportunity to gather medical and lifestyle histories and photographic data of identical twins at the annual Twins Days Festival in Twinsburg, Ohio, and designed this study to examine the aging effects of smoking on the faces of identical twins.

The Twins Days Festival is an annual gathering of twins and multiples in Twinsburg, Ohio. The Department of Plastic Surgery at Case Western Reserve University obtained comprehensive medical and lifestyle histories of twins by means of questionnaire at the festival between 2007 and 2010. Professional photographers took standardized digital photographs of the participants in outdoor booths with overhead shades. Consent was obtained from all participating twins, and this study was commenced with institutional review board approval. (More)
