Sleep is one of the most generous things you can do for your body, and one of the most underrated. It is free, it is available every single night, and what happens during those hours is more powerful than most things you could buy. Your skin knows this. Science has known about it for a long time.
Three things that happen while you sleep that cannot happen any other way:
It repairs itself. Between 11pm and 2am, skin cell turnover peaks and collagen synthesis kicks in. Your skin is literally rebuilding. It can only do this in deep sleep.
Cortisol drops. Poor sleep keeps stress hormones elevated, which accelerates collagen breakdown, disrupts your skin barrier, and drives inflammation. It shows up as dullness and sensitivity, and, over time, as faster, more visible aging.
Hydration rebalances. Your body regulates water loss through the skin overnight. Disrupt that, and you wake up with skin that looks flat and dehydrated. It is not in your head.
Five things that actually make a difference:
Keep a consistent wake time, even on weekends. Your circadian rhythm responds to regularity above everything else.
Lower your body temperature before bed. Cool room, lukewarm shower. Heat delays sleep onset.
Cut light exposure after 9pm. Blue light suppresses melatonin. Dim the whole room, not just your phone.
Avoid alcohol within three hours of sleep. It fragments your deep sleep and REM cycles in ways you feel the next day.
Build a ritual. A consistent wind-down signal matters more than any supplement.

On a Personal Note...
For most of my adult life, I ran for five or six hours and was genuinely proud of it. I could do it all: dinners, socializing until 2am, then up at seven to work out. I thought that was a sign of strength, that I was someone who did not need much. I wore it like it said something good about me.
That is very much a thing of the past. Somewhere in the last year, my body decided it was done with that arrangement, and I slowly had to accept that what I thought was functioning well was actually just functioning. When I started actually sleeping, eight hours, sometimes more, I realized how different I could feel. Clearer, calmer, better skin, better energy. The difference was not subtle.
I am sure this is obvious to many readers. It was not obvious to me for the longest time. I genuinely thought I was one of those people who just needed less. I was not. I was just used to running on empty.
I now have a sleep ritual, which still feels slightly unlike me to say out loud. Lights low from nine, phone down, De Mamiel Settle on my chest and wrists, the silk pillowcase always. And I have come to see this as self-care in the truest sense: not a treat, not a luxury, just giving your body what it actually needs.
