We all know smoking is bad for our health... but these photos PROVE it's bad for your looks! Compare the twin that smokes with the one that doesn't if you don't believe us

A new study provides shocking photographic evidence of the devastating effects that cigarette addiction can have on a person's face. Researchers interviewed more than 70 pairs of identical twins where one was a regular smoker. They found that the smokers showed considerably more signs of premature facial aging. The female twin on the right is a smoker, while her sister is a nonsmoker and has less creases around the nose and mouth as a result. Both of these male twins smoked, but the twin on the right smoked 14 years longer than his brother and looks older as a consequence. Smoking reduces oxygen to the skin, which also decreases blood circulation, and that can result in weathered, wrinkled, older-looking skin
