Robert C. Spitale of Stanford University School of Medicine in California and colleagues say cigarette smoking is well-known to be associated with accelerated skin aging, cardiovascular disease and lung cancer, in large part due to oxidative stress.
"In this study, we explore the potential effects of commonly available oral supplements containing antioxidants, vitamins and omega-3 fatty acids on 11 smokers compared to 17 non-smokers," Spitale said in a statement. "At baseline and after 12 weeks of supplementation, metabolomic analysis was performed on serum by liquid and gas chromatography with mass spectroscopy. Furthermore, clinical parameters of skin aging was assessed by three dermatologist raters who did not know the subjects' age and smoking status."
The study, published in the journal Genome Medicine, found smokers who took the supplement had an increase in skin elasticity, but non-smokers did not enjoy the same benefit. The researchers said they found that while complexion analysis software revealed decreases in the number of ultraviolet spots increased elasticity in smokers but not in non-smokers.
"Our study suggests that oral supplementation -- in particular commonly available antioxidants, vitamins and omega-3 fatty acids -- affects these individuals in a way that is unique, compared to non-smokers on a broad level," Spitale said.
