Risk of Blue Light for your Skin

Most of us are aware of the harmful effects of ultraviolet (UV) radiation from the sun, but we don’t often think about the blue light that comes from our electronic screens. Blue light is a type of visible light that has a shorter wavelength than other colors. This means that it produces more energy.

While the sun is the main source of blue light, we’re also exposed to it from artificial sources like computers, tablets, phones, and LED lights. And this exposure is on the rise. We’re spending more time than ever looking at screens, and the average American household has more than five electronic devices. The harmful effects of blue light were first discovered in the early 1990s. Scientists found that blue light could damage the retina, the sensitive tissue at the back of the eye.

Studies also linked blue light exposure to conditions like macular degeneration, which can lead to blindness.

While more research is needed, there’s growing evidence that blue light exposure can also have negative effects on the skin. Just like the eyes, the skin has receptors that are sensitive to blue light.

When blue light hits these receptors, it triggers a series of events that can lead to cell damage.

Some of the effects of blue light on the skin include:

  • premature aging
  • wrinkles
  • sun spots
  • hyperpigmentation
  • melasma
  • decreased skin elasticity
  • poor wound healing
  • inflammation
  • acne
