The effects of chronic poor sleep quality on human skin function and visible signs of ageing have not been elucidated.</p> </sec> <sec id="ced12455-sec-0002" sec-type="section"> <title>Aim</title> <p>To evaluate the effect of chronic poor sleep quality on measures of skin health and ageing. Self‐perceived satisfaction with appearance was also assessed.</p> </sec> <sec id="ced12455-sec-0003" sec-type="section"> <title>Methods</title> <p>60 healthy caucasian women, who were categorized as poor quality sleepers [Pittsburg Sleep Quality Index (PSQI) > 5, sleep duration ≤ 5 h] or good quality sleepers (PSQI ≤ 5, sleep duration 7–9 h). A validated clinical tool, SCINEXA<sup>TM</sup>, was used to assess intrinsic and extrinsic skin ageing. Dark under‐eye circles were evaluated using standardized photos. Measurement of <italic>in vivo</italic> transepidermal water loss (TEWL) was used to assess recovery of the skin barrier after tape stripping. Subjects were exposed to simulated solar ultraviolet light, and recovery from erythema was monitored. Subjects also completed a questionnaire evaluating self‐perception of attractiveness.</p> </sec> <sec id="ced12455-sec-0004" sec-type="section"> <title>Results</title> <p>Good sleepers had significantly lower intrinsic skin ageing scores by SCINEXA<sup>TM</sup>. At baseline, poor sleepers had significantly higher levels of TEWL. At 72 h after tape stripping, good sleepers had 30% greater barrier recovery compared with poor sleepers. At 24 h after exposure to ultraviolet light, good sleepers had significantly better recovery from erythema. Good sleepers also reported a significantly better perception of their appearance and physical attractiveness compared with poor sleepers.</p> </sec> <sec id="ced12455-sec-0005" sec-type="section"> <title>Conclusions</title> <p>This study indicates that chronic poor sleep quality is associated with increased signs of intrinsic ageing, diminished skin barrier function and lower satisfaction with appearance.</p> </sec> </abstract>
