During the day, skin cells are in defence mode, working to protect themselves from UV exposure and free radical damage. When the sun goes down our skin switches into regeneration mode, repairing daytime damage and boosting the production of substances that protect and renew.
The mind and body enter a biological regeneration mode while we sleep, performing reparative functions that can't occur when we are awake. The brain clears out waste products, ramps up its production of protective brain cells and consolidates memories to enhance problem-solving and creativity.
The science of beauty sleep
The skin follows a similar regenerative process. Sleep-inducing melatonin is produced at night when we sleep in complete darkness and it allows our bodies to go into deep, recuperative, immune-enhancing sleep.
As melatonin production rises, levels of cortisol, the stress hormone, begins to fall, allowing skin to repair and protect itself from external damage. Sleep allows the body to make more collagen which minimises fine lines and releases more human growth hormone which increases muscle mass and strengthens skin.
Blood flow to the skin also increases which helps to boost the healthy-glow of your skin. Melatonin secretion starts at around 9:00pm with the maximum in night-time skin repair being around 11:00pm.
How to maximise skin regeneration whilst you sleep
Finding a skincare product designed especially to support your skin's night-time regeneration processes is the perfect way to enhance your beauty sleep.
Introducing Dermalogica's new Sound Sleep Cocoon, a night gel-cream that harnesses the power of nature with science to promote sound sleep and healthy, radiant skin.
The revitalising treatment gel-cream optimises night-time skin recovery with active ingredients such as Peruvian Silk Tree Bark, Fruits of the Wu-Zu-Yu Extract, Kakadu Plum and Tamarind Seed Extract selected for their ability to rejuvenate skin and reduce the signs of fatigue.
To promote a deep, restful sleep, Lavendin Oil is encapsulated in motion-activated microcapsules that allow the calming scent to be released as you massage the Sleep Cocoon into your skin and throughout the night as you toss and turn. Additional essential oils of Sandalwood and Patchouli calm the skin and soothe the senses.
If you struggle to switch off at bed time, turn off your all your tech devices and dim the lights half an hour before bedtime. Make your room as dark as possible using blackout blinds or curtains and ensure the room is cool.
Try to avoid alcohol, sugar and caffeine before bed; try a soothing camomile tea instead and take time to care for your skin - ideally applying night-time products between 9:00-11:00pm.
