Blue Light: The Hidden Threat to Skin Health

If you’re someone that has age spots, sagging skin, hyperpigmentation or wants to avoid unsightly skin issues, this post is for you!

In the modern digital world, we are constantly exposed to blue light emitted from electronic devices such as smartphones, tablets, computers, TVs and even indoor lighting. Have you ever noticed how bright grocery stores are and how blue the actual light is? Unfortunately, its every where and it’s incredibly toxic to our body as well as any living creature including our fur babies!

So what is blue light & how can it damage the skin?

It’s a high-energy light with a wavelength between 400 and 495 nanometers but has a higher frequency and shorter wavelength than other colors such as red, green, or yellow. The sun itself has all spectrums of color making it the best form of light for our bodies in general.

Excessive blue light exposure can lead to skin damage through several mechanisms:

First, through oxidative stress. Blue light generates reactive oxygen species (ROS), which are unstable molecules that damage skin cells and DNA and they can contribute to premature aging, wrinkles, and age spots.

Secondly they can trigger the release of inflammatory mediators, which can cause redness, swelling, and irritation. This chronic inflammation can lead to skin damage and impaired skin barrier function.

This means that blue light can break down collagen, which leads to wrinkles, sagging, and a loss of firmness.
And there have been some studies showing that blue light may increase the risk of skin cancer by damaging DNA and suppressing immune function. Yikes!

Symptoms of Blue Light Damage Include:

* Premature aging: Wrinkles, fine lines, age spots
* Hyperpigmentation aka melasma which are  dark spots or patches on the skin
* Redness and irritation
* Dryness and dehydration
* Loss of firmness and elasticity

Let’s talk about how we can protect your skin from blue light:

  • Use blue light filters: install blue light filters on your devices to block out harmful wavelengths. I use f.lux on my computer
  • Limit screen time: by reduce your exposure to blue light-emitting devices
  • Use antioxidant-rich skincare products: Which help to neutralize free radicals and protect the skin from oxidative damage. Look for skincare products that contain antioxidants such as vitamin C, vitamin E, and green tea extract.
  • IV therapy: particularly vitamin C and glutathione IV therapy that also provide antioxidant protection from the inside of your body.
  • Use Red light therapy: which has been shown to benefit aging skin by activating fibroblasts, modulating inflammation and even moderating sebum or oil production. My favorite red light therapy device is the EMR-TEK, so much so that I have two of them. One for the humans in our family and the other for our fur babies! Which is ideal for anyone that has house pets. Animals naturally are habituated to the outdoors; their body’s need more red light. This is why you’ll often see your dog/cat sunbathing. They’re trying to soak in all the red light from the sun! So if your home doesn’t get a lot of light, it would be great to get them outdoors more so and to get both you and them an EMR-Tek device. And here’s a 20% discount code for the EMR-TEK device!
  • Wear blue blocking glasses which have filters in their lenses that block blue light. This can help to prevent the blue light from manipulating the immune systems effect on skin health. Lucia’s are my favorite. Add discount code DrNirvana10 for a 10% discount.
