title: Improvement in skin color achieved by smoking cessation.
abstract: It has been well known that habitual smoking accelerates premature skin ageing recognized as 'smoker's face'. However, the effect of smoking cessation on the appearance of skin has not been elucidated. The aim of this study was to evaluate objectively the effect of smoking cessation on the skin's appearance. The stratum corneum carbonyl protein level and skin colour of the cheek and the hand were measured. The change before and during the smoking cessation treatment (0, 2, 4, 8 and 12 weeks), and the success or failure in smoking cessation, was compared and examined. Eighty-four cases who had smoking cessation treatment were examined. The level of the stratum corneum carbonyl protein did not show any difference comparing before and after treatment for the smoking cessation success group and the failure group. The lightness of skin colour showed an upward tendency 4-12 weeks after starting the treatment in the success group and increased significantly compared with the failure group. The redness showed a significant decrease in comparison with before the treatment, and it also showed a significant decrease compared with the failure group. The yellowness did not show any clear tendency. Also, the haemoglobin showed a decreased tendency. Furthermore, multivariate statistical analysis showed a possibility that the lightness and haemoglobin could be changed by smoking cessation treatment. In conclusion, our study showed that an upward tendency of skin lightness was seen to correspond with a haemoglobin decrease accompanied by smoking cessation. If we can easily measure skin improvement as an effect of smoking cessation, it is thought to be a useful aid for smoking cessation support.
