With review and feedback from CEENTA facial plastic surgeon Neela Rao, MD (Fort Mill)
We’re familiar with the effect of blue light on your eyes and sleep, but is all that screen time having an impact on your skin, too?
What is blue light?
Blue light is a portion of the visible light spectrum that is commonly emitted from not just the sun, but smartphones, tablets, and other electronic devices. While blue light is important during the day because it improves attention, reaction times, and mood, it receives a lot of negative attention because it is also known to disrupt sleep patterns by preventing our brains from producing melatonin.
How does blue light affect your skin?
Studies indicate that increased blue light exposure can cause premature skin cell aging, cell shrinkage, and even cell death. Blue light is also believed to alter skin pigmentation and cause an increase in swelling and redness. Also, studies say that, like with your melatonin production, too much blue light can also disrupt your skin’s regenerative cycle.
That said, it’s also important to note that research into the effects of blue light on skin is all comparatively new, and further research is needed before any concrete conclusions are drawn.
Can blue light be beneficial to skin?
While there is concern about the negative effects of too much blue light, there are medical indications for blue light therapy that can be used to treat skin lesions and acne, CEENTA facial plastic surgeon Neela Rao, MD, said.
How can I protect my skin from excess blue light?
Wear sunblock with zinc oxide of SPF 30 if you are going to spend time outside. This will protect your skin from not just blue light, but ultraviolet light, too. Additionally, consider wearing long sleeves and covering your skin for sun protection. Try to limit your screen time, too.
