Blue Light Skin Damage Prevention

Blue light, also known as high-energy visible (HEV) light, has a bad reputation. These wavelengths commonly emitted from smartphones and computers don’t just harm our vision, they disrupt our circadian rhythm and deplete melatonin too, making it harder to sleep.

What’s news to most of us is that blue light can also lead to premature skin aging—a fresh kind of hell.

How blue light causes skin damage

When blue light penetrates the skin, reactive oxygen species are generated. This causes DNA damage, which triggers inflammation as it breaks down healthy collagen. A study revealed that long-term blue light exposure can lead to redness, swelling, and hyperpigmentation.

Skin sites after exposure to blue light

Sunlight is the main source of HEV light to which we’re exposed, while digital devices emit only a fraction of the sun’s radiation. However, the amount of time we spend glued to our screens is significantly higher, so here are a few steps you can take to minimise daily blue light exposure.

Ways to reduce blue light exposure

Use blue light filtering apps

F.lux, a blue light filtering app, decreases blue light brightness and intensity within each pixel. It uses geolocation to calibrate your display’s colour temperature to the time of day. You can customise your screen’s colour or pick from one of their recommended filters.

If you’re an iPhone user, try activating your ‘Night Shift’ mode, Apple’s solution to counteract the effects of blue light. You can input your preferred start and end times for the app to take effect. There’s also an option to manually enable and disable the feature.

Try ‘Twilight’ if you’re on Android. Just like F.lux, the app adjusts your screen’s colour temperature based on the time of day. It filters blue light and protects your eyes and skin with a soft, pleasant red hue.

Purchase blue light screen shields
