Cell phones. We need them, love them, and are addicted to using them. They do a lot of good like keeping us connected to society and provide knowledge at our fingertips. However they can also do a few not so great things, like damaging your eyesight and also your skin. This is due to the blue light they omit.

What is blue light?

Blue light is defined as a visible light spectrum color, and also has high-energy visible (HEV) light. Shari Marchbein, a board-certified dermatologist and clinical assistant professor of dermatology at New York University School of Medicine, notes that blue light is a type of visible light that has a high-energy and short-wavelength. This should not be confused with UVA or UVB rays. 

Does blue light equal bad skin? 

Marchbein explains that High Energy Visible (HEV) light is a cause for concern, as it is present on the visible light spectrum, specifically in blue wavelengths. This light is not only found in sun exposure, but is also emitted from computer screens, cell phones, and other digital devices. It is purported that much of our lives are spent viewing screens. Because we spend so much time on those screens, the constant exposure just isn’t very healthy for not only our eyes but our skin as well. 

What exactly is blue light doing to our skin?

More and more skincare products are now advertising blue light blocking technology. So, does that mean it is damaging your skin? According to Marchbein, the most reliable evidence suggests that blue light can induce brown spots on the skin, hyperpigmentation such as melasma, and potentially lead to premature aging and degeneration of collagen, resulting in wrinkles and loose skin. We don’t like the sound of that at all. 

How to protect your skin against blue light

So, what can we do? We can’t exactly get away from our cell phones for too long. Most people use them for work as well as to communicate on a daily basis. But there are a few things you can do to help you receive the smallest amount of blue light possible. Here are 3 simple things you can do. Your skin and appearance will thank you!

• Wear sunscreen: This is hands down the best thing you can do. Not only when you go outside, but sitting inside as well. Don’t forget to reapply after washing your hands or doing the dishes. 
• Use antioxidants: These are natural blue light blockers for your skin. Look for them in your serums, creams, and face wash. 
• Get a blue light screen shield ASAP: This simple investment can help your skin bigtime. This helps decrease the amount of blue light you get drastically in day to day use.
