Make sure you wash your face and put on your skin cream before 11pm at night! Because research shows, between 11pm and midnight is the peak hour for your skin to repair and renew itself. And that’s true whether you’re asleep – or just about to start watching Jimmy Fallon. Because it’s about the cycle of natural light – not your sleep cycles. So says the Journal Of Drugs in Dermatology. So wash your face and slather it with your skin cream by 11pm.
