We’ve all been taught that UVA and UVB rays have damaging effects on the skin. But recently, researchers have discovered that the light emitted by your beloved smartphones, tablets, TV, and computer screens could potentially harm your skin
In this blog, we’ll be talking about blue light and its effect on the health of your skin. Let’s get started!
What is Blue Light?
Blue light, also called high-energy visible light, is a high-frequency and short wave light belonging to the violet and blue band of the spectrum. It is the only part of the light that is visible to the naked eye.
Our exposure to blue light typically comes from the sun. However, devices like smartphones, tablets, televisions, and LED bulbs also emit this kind of light.
Normal exposure to blue light emitted by the sun is actually beneficial. It can stimulate alertness, improve memory, and elevate your mood.
The problem comes when you are constantly exposed to it at night from electronic devices. This is because blue light can also disrupt your body’s circadian rhythm and affect the quality of your sleep.
What Does it Do to the Skin?
Apart from affecting sleep, dermatologists have discovered that blue light can also affect your skin.
While further research is needed to verify this, initial studies have shown evidence that blue light can penetrate the skin and cause oxidative damage This can result in inflammation and the breakdown of collagen and elastin as well as the development of hyperpigmentation.
Preventing Damage Caused by Blue Light
The science surrounding blue light is still in its early stages. However, you can take extra caution to keep your skin protected from its potential ill effects.
You can limit your usage of electronic devices especially at night. You can also install covers that block blue light from your smartphones and computers.
Since studies suggest that blue light plays a role in photo-aging, it is more important now to apply sunscreen. Go for mineral sunscreens that contain zinc oxide or titanium dioxide since they physically block harmful light.
It is also important to use products that have antioxidants that prevent oxidative and free radical damage. Products containing vitamin C and E can help prevent the aging and damaging effects of blight light on your skin.
