The study of 1,000 women found that over 40 per cent of those who smoked had non-inflammatory acne, compared with just 10 per cent of non-smokers. The researchers suggest that a number of factors are involved. Smokers were found to have half the skin secretions of vitamin E compared with the non-smokers, as well as other variations in skin make-up (British Journal of Dermatology Online).
