We can’t say much about the science behind sleep making you beautiful, but we do know the term dates to at least 1828. Beauty sleep, occasionally known as beauty rest, is “sleep before midnight” suggesting that the earlier you go to bed, the more beautiful you will be.
“Beauty sleep is very much a real thing,” says family nurse practitioner, aesthetic injector, and founder of Aion Aesthetics, Akis Ntonos. “Many of the restorative capabilities our skin has are achieved during our night sleep, since cells regenerate quicker at nighttime.”
