How blue light affects skin

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut elit tellus, luctus nec ullamcorper mattis, pulvinar dapibus leo.

There have been many reports, news articles, and opinion pieces regarding how screen time affects our eyes, attention span, brain development, sleep quality, emotional health, and more. But what about how this type of light affects our skin?

Several studies have suggested that prolonged exposure to blue light can increase hyperpigmentation (dark spots on the skin, also called sunspots) as well as wrinkles and fine lines.

While the research regarding blue light and skin isn’t overwhelming, it’s worth paying attention to, especially considering the dozens of other negative side effects of too much screen time.

Encourage customers to do their skin (and body) a favour by following these tips to reduce blue light in their life:

  • Less screen time. This is a no-brainer. To reduce blue light exposure, simply spend considerably less time on devices that emit blue light. If that means use an app-blocking app on your phone to limit your most addictive apps, go for it.
  • Enable “blue light shield” mode. This mode (also called comfort, reading, or night mode) comes standard on most new phones, laptops, and tablets. Find it in your settings, turn it on, and forget about it.
  • Buy a blue light filter. Many companies make physical blue light filters for your plethora of devices. They aren’t very expensive, so it’s a worthy investment.
  • Wear blue light glasses when using a screen to protect the eyes and brain.

A constant barrage of blue light may cause long-term damage to skin. Client’s should play it safe and limit exposure early to keep skin at its best. Encourage them to use a great anti-oxidant serum twice daily to help give their skin that extra protection.
