Many of us are unaware that the blue light produced by our laptop and smartphone displays may also harm our skin. Here’s how to protect your skin against such technological gadgets.

People who are stranded at home due to the lockdown are spending the majority of their time hooked to laptops, television sets, desktop computers, and cellphones. Long periods of time spent with such electronic gadgets result in increased exposure to blue light, which is damaging to your eyes and skin.

Blue light, also known as HEV (High Energy Visible), is mostly found in sunshine, but it is also produced by LED lights, fluorescent lights, computer displays, smart phone screens, and tablet screens. Excessive exposure to this high intensity light has been linked to pigmentation, inflammation, wrinkles, and accelerated ageing, according to research. The light from the displays may cause collagen breakdown, resulting in black spots and hyperpigmentation. According to scientists, blue light exposure may also cause DNA damage, resulting in DNA mutations, which can lead to skin cancer and ageing.

Blue light may also impair your vision if you are exposed to it for an extended period of time. The light projected by the screen may destroy photoreceptors (light-sensitive cells) in the retina, which are required for vision. Excessive blue light exposure may also reduce melatonin levels and disturb sleep.

How to Guard Your Skin Against Blue Light

We take many measures to protect our skin from the sun, but few people are aware of blue light and the danger it presents. A certain amount of blue light from the sun is good to humans, but man-made light produced by our phones and computers has no such benefits. And, since we are always on our phones, it has become a major issue. Since it is impossible to avoid using a laptop or a mobile device entirely, there are certain precautions you may take to protect your skin against blue light. Among them are:

Apply sunscreen before going outside

Wearing a sunscreen with a high SPF content is the best method to protect your skin against blue light. Sunscreen should be used even while you are inside and reapplied every two hours.

Dermatologists suggest using a broad-spectrum physical sunscreen with zinc oxide and iron dioxide to protect your skin against UVA and blue radiation. A mixture that also includes antioxidants may aid in the reduction of free radicals caused by UV radiation and blue light.

Make use of a blue light screen shield

Another method to shield your skin from blue light is to use a blue light screen protector on your phone or tablet. E-commerce sites provide a plethora of choices. It’s an inexpensive fix that eliminates the need to bother about skin maintenance.

Consume a diet high in antioxidants

According to experts, using topical antioxidants may guard against the harmful effects of blue light emitted by gadgets.

Antioxidants, such as vitamin E, are depleted when the skin is exposed to excessive free radicals. You may strengthen your skin’s defence against oxidative environmental damage by using topical antioxidants and consuming an antioxidant-rich diet. Fresh fruits and vegetables high in antioxidants include blueberries, strawberries, artichokes, kale beans, spinach, and so on. Dark chocolate is an excellent source of antioxidants, which is great news for chocolate lovers. The antioxidants in cocoa and dark chocolate may also offer additional health advantages such as decreased inflammation and risk factors for heart disease.
