The skincare industry has a valuation of $135 billion and counting, with the average woman spending about $313 per month on beauty products and rituals according to 2017 study. Thinking about these products in dollars and cents, I became curious. How can we ensure that our nightly skin routines are working to keep us healthy and radiant? To better understand what our skin does while we’re sleeping, plus what time to sleep for skin renewal, I spoke with Ronald Moy, MD, a renowned cosmetic surgeon and dermatologist based in Beverly Hills.
WHY IS SLEEP SO IMPORTANT FOR OUR SKIN?
Adequate sleep is essential for our bodies to function properly from both mental and physical perspectives. When we don’t get enough sleep, it can show on our faces, even if we’re meticulous about multi-step skincare routines. “We accumulate sun damage during the daytime, and our DNA repairs enzyme damage while we’re sleeping,” Dr. Moy explains.
Aside from sun damage, our skin wards off pollution and free radicals that can cause other forms of wear and tear. Human growth hormones work to repair these issues while we’re sleeping. Produced by the pituitary gland, human growth hormone (HGH) stimulates cell regeneration. Levels can rise during exercise and sleep, but peak during puberty and decline with age.
WHAT HAPPENS TO OUR SKIN WHILE WE SLEEP?
Around 9 p.m., our bodies start to wind down and feel the effects of melatonin, and the same goes for our skin. The next part of our restorative sleep cycle begins at 11 p.m., whether we’re actually asleep or not. Sleeping allows the skin to absorb our beloved products while our skin cells regenerate, thus creating more collagen and stronger, healthier skin. Read more…
