The Scary Difference Between Smoking and Non-Smoking Identical Twins


The Department of Plastic Surgery of Case Western Reserve University in Ohio, USA,  has made it very clear how tobacco influences and accelerates changes in people’s bodies. They focus on many series of twins, with the proviso that one has smoked longer than the other.

Side by side, with the camera focused on their faces, we can see the differences of time and lifestyle between the twins. Not everything will depend on only cigarettes, but to make the results more reliable, the researchers included a questionnaire to each portrayed (asking about other habits that could accelerate aging, such as stress or alcohol consumption), and a panel of three judges, blindfolded, to analyze the facial expressions and the level of wrinkles on the siblings.

The conclusions point in the same direction: Smoking favors the aging and degradation of the skin. The technical explanation is given by one of the researchers, Bahman Guyuron – “Smoking reduces the formation of collagen, resulting in the degradation of collagen and reduces circulation to the skin. In addition, nicotine reduces the skin thickness. All this reduces the elasticity of the skin and causes premature aging.”
