If you’re spending more time in front of digital devices, you should know how the blue light from them affects you. While there are positive effects on the body from blue light, it’s important to be aware of the potential negative effects it can have on your skin. This article will help you to understand and protect your skin from blue light.
Blue light is important to understand from a skincare perspective because it can contribute to hyperpigmentation and photoaging. Photoaging is premature aging of the skin caused by the sun and some artificial light sources.
To make sure you’re getting the most out of your investment in clean skincare, make sure you’re reducing your exposure to sources of potential skin damage in your environment. Let’s start with what blue light is and why it’s important, and then we’ll cover to how to protect your skin from it.
Blue light, also called HEV light, is a high-energy, short-wavelength light. It is part of the spectrum of visible light and is emitted from digital devices like computer and cell phone screens, as well as the sun. With increased working from home, virtual meetings, and staying in for movie nights in the era of social distancing, blue light exposure is significantly increasing for many people.
Blue light has both positive and negative effects on the body. It helps regulate your circadian rhythm and improves your mood. Unfortunately, it’s also linked to macular degeneration in the eyes. Exposure to significant amounts of blue light on the skin has the potential to cause:
In a study published in Oxidative Medicine and Cellular Longevity in 2015, researchers found that exposure to blue light may stimulate the production of free radicals in the skin. Free radical production can accelerate premature aging of the skin. Signs of aging can include wrinkles, hyperpigmentation, and loss of skin elasticity.
If you want your skin to look its best without makeup, one of the keys is to reduce your exposure to things that cause hyperpigmentation of the skin. Hyperpigmentation occurs when patches of skin appear darker than the surrounding areas due to increased melanin production. This is why we’re always advised to wear sun protection every day.
Liver spots, or sunspots as they’re also known, are a type of hyperpigmentation. Melasma is another type of hyperpigmentation that can be caused by hormonal changes.
Protecting your skin and eyes from blue light emitted from your screens can be simple. Here are five easy ways to prevent potential photo-aging while you’re working or watching Netflix.
While research in this area is new, we do have some studies that point to blue light’s negative effects on the skin. To avoid premature aging and hyperpigmentation, protect your skin and eyes from prolonged exposure to blue light from your device screens and the sun. Remember to cut down on the wear and tear of your skin so that you’re giving your skincare products the best chance they can to keep your skin evenly toned and looking youthful.
