Our awareness of blue light is constantly evolving. 2021 has revealed some trail blazing research which gives us a real wake up call to the damage our skin suffers around the clock.
Pioneering research from Dr Mark Birch Machin, Professor of Molecular Dermatology at Newcastle University reveals that visible light from the sun, particularly blue light, can penetrate the skin at a deeper level that UV rays alone and can actually increase the amount of damage that UV does to skin.
In addition to brand new science, skin expert and practicing GP, Dr Johanna Ward has highlighted the need to protect skin against blue light from a dermatologist's perspective, having seen the visible effects of blue light first hand in-clinic. Jo is an award winning GP who is dedicated to preventative skincare.
In the evenings, many of us switch on our LED lights for a cosy night in, often in front of a digital screen whether that be a TV, smartphone, iPad or laptop. These devices, plus the blue light from our lightbulbs contribute to the amount of blue light our skin absorbs.
The effect of blue light on the skin can last long after we lock our phones before we go to sleep. Our skin and eyes are designed to react to blue light, making our bodies believe that it's daytime. Our natural skin repair cycle happens at night when our skin is in a state of rest. Keeping it 'awake' with blue light well into the evening means it cannot carry out its repair cycle effectively which leads skin to appear visibly stressed.
Dr Jo Ward recommends an hour of no screen time before bed to help your skin settle into its repair rhythm. Beauty sleep is not a myth.
