How Blue Light Affects Your Skin and How to Shield It
We live in a world where everyone walks around holding up their phones, spending an average of 3-6 hours in front of a screen. However, it’s important to pause and consider the impact it may have on our skin. We are constantly surrounded by screens, from our smartphones to laptops and tablets. But have you ever thought about how this constant exposure to blue light affects our skin?
Blue light, also known as high-energy visible light (HEV), is emitted by digital screens and LED lights. There is evidence that prolonged exposure to blue light can damage our skin.
In this article, we’ll look at the risks of exposure to blue light and ways to protect our skin from its effects.
Understand the impact
Blue light has been shown to penetrate deeper into our skin compared to UVA and UVB rays – it affects the layer responsible for collagen and elastin production. This can lead to several skin-related concerns such as:
1. Premature aging
Studies have indicated that blue light can increase the signs of aging, including wrinkles, fine lines, and hyperpigmentation. This occurs when the skin is exposed to blue light, it generates reactive oxygen species—chemicals that damage collagen and elastin fibers.
2. Disruption of skin barrier
Exposure to blue light can weaken the skin barrier, allowing more irritants and allergens into your pores, which results in dryness and makes the skin more vulnerable to moisture imbalance and pollution.
3. Inflammation and sensitivity
Blue light exposure can trigger inflammation, leading to redness, irritation, and sensitivity. It can be more severe for those with existing skin conditions, as it may worsen their symptoms.
Now that we are more informed of the effect Blue Light has on our skin, it is important to take action by protecting our skin from this harmful light.
In the next episode, we will discover different methods we can follow to prevent damage done by this radiation and how to apply it to our everyday lives.
