What’s the deal with blue light & your skin? Well, it's more than skin deep.
When you hear about blue light in the context of skincare, it's often a convo about "digital aging" or comparing to UV light, but there's even more to it.
"Digital aging" is a misconception. You get 6x more blue light exposure from the sun than you do from your devices. Blue light from the sun does cause photoaging through oxidative stress, hyperpigmentation, and collagen degradation.1 But there’s a lesser-known consequence to blue light: nighttime exposure to blue light disrupts your circadian rhythm, and this means affects more than just sleep.2
Circadian rhythm disruptions may cause a bunch of health issues, including dermatological conditions.3 Melatonin synchronizes your circadian rhythm and is responsible for repairing your skin at night, especially of blue light damage.4
In summary: Blue light at night ➡️ disrupted circadian rhythm ➡️ inhibited melatonin production & release ➡️ impaired skin healing ➡️ persistent skin damage.
So, what can you do about it?
Avoid blue light at night - and yes, this includes digital screens/electronic devices, as well as fluorescent & LED lighting.5 Opt for red or orange nightlights instead.6 Consider using melatonin to help keep your circadian rhythm in sync.7 Mella's melatonin-infused skincare supports your body's repair cycle without causing daytime drowsiness.8
