We’ve all heard of beauty sleep – but how does settling into bed worthwhile for our skin? It’s all about science – and Byrdie helped us fill in the gaps.
Just as we start to get sleepy, around 9 p.m., our skin starts to wind down too. We define the hours between 9 to 11 p.m. at the evening phase. This phase is the prelude to sleep when skin is most able to absorb topical treatments and DNA repair is boosted. Moreover, the sleep hormone melatonin begins to rise a few hours before bedtime, enhancing the feeling of tiredness as well as increasing our skin’s ability to repair itself at night. Melatonin is a pretty smart hormone: As well as making us sleepy, it works to counteract damage to the skin during the day from aggressors like UV and pollution.
The other hormone that kicks in while we’re sleeping is HGH (the human growth hormone), which is responsible for accelerating skin’s repair and cell regeneration. We know that between 11 p.m. and 4 a.m., our cell production can double, and if we’re in a deep sleep, you could see cell turnover increase by three times between the hours of 2 a.m. and 4 a.m.
This is key to great skin. It’s our “skin’s stem cells, the mother cells responsible for making fresh new cells and replacing aged cells, that reproduce at this time and the skin’s layers are renewed.”
During the nighttime, as well as being more active, skin is more permeable too. It’s warmer, so it’s more receptive to the skincare products you apply. While this is brilliant, the flip side is that you will lose moisture. If things can get in, then things can get out. The morning phase is when “transepidermal water loss” through the skin is at its highest.
