It’s no secret that sun exposure is bad for your skin. But did you know that blue light from our digital screens can do lasting damage too?
In fact, certain aspects of blue light might be even worse than UV.
Importantly, although the impact is not fully known, blue light also penetrates deeper than UV rays
A study in the Journal of Investigative Dermatology found that for some people, visible light like blue light actually produces darker and longer-lasting hyperpigmentation than UVA rays do.
Adding to the confusion, is that blue light therapy is often used to treat acne prone treat and reduce the severity of breakouts.
However, dermatologists have agreed that long exposure to blue light increases the signs of premature aging and the production of free radicals.
Therefore it is important to protect yourself, take breaks, and turn on night mode.
