RESUMO
This study aimed to investigate the association between smoking status and facial wrinkling as well as other confounding variables [age, sex, sun exposure and body mass index [BMI]]. A cross sectional study was conducted including 329 cases who never smoke [165 men and 164 women], 181 former smokers [127 men and 54 women] and 134 current smokers [92 men and 42 women] aged 40 years and above. Facial wrinkling and facial wrinkle scores were assessed using scoring system. By controlling the potential confounding variables, the results showed that smoking increased the risk for facial wrinkling nearly two folds among men and women above 40 years old. Women also appeared to be more susceptible to the wrinkling effect of smoking. It was concluded that when smoking and excessive sun exposure coexisted, the effects on wrinkling was multiplicative
