Sleep and Skin
Does sleep affect your skin?
Small studies show links and short-term change only
Partly. In a study of 60 women, poor sleepers had more signs of skin ageing and a slower skin barrier recovery than good sleepers, and two nights of short sleep lowered skin hydration in 24 others. The studies are small and cannot say how much extra sleep would reverse anything.
Chronic poor sleep
A study compared 60 women who slept badly (five hours or less, with a poor sleep-quality score) with women who slept seven to nine hours. Good sleepers had lower scores for intrinsic skin ageing, about 30 per cent better skin barrier recovery after the barrier was disrupted, and better recovery from sun-induced redness. Good sleepers were also happier with their appearance. This was an observational study, so it cannot show that sleep alone caused the differences.
A couple of short nights
In 24 good sleepers limited to three hours a night for two nights, skin hydration fell, water loss through the skin rose, and face photographs became less bright and less saturated. In an earlier experiment, observers rating photographs taken after 31 hours without sleep saw redder, more swollen eyes, darker under-eye circles, paler skin and more fine lines.
What it means for you
These studies describe what sleep loss looks like, not what extra sleep fixes. A regular bedtime is a good habit for many reasons, so we treat it as general wellbeing rather than a skin treatment.
Questions people ask
Poor sleepers showed more signs of ageing and slower barrier recovery in a study of 60 women, but we have no trial showing that sleeping more reverses them.
In an experiment, observers rated faces after 31 hours awake as having darker circles under the eyes, among other cues. That is a short-term change in appearance.
