BLUE LIGHT- WHAT IS IT?

HOW IS BLUE LIGHT RUINING OUR SKIN?

Blue light is a type of radiation that has a wavelength between 400 nm to 500nm approximately. It is very similar to ultraviolet or UV radiation and is also called high high-frequency light or HEV (High Energy Visible). It is naturally emitted by the sun, but it can also be emitted with the help of artificial sources. Computers, smartphones, tablets, television screens, and LED light bulbs are a few of the artificial sources which emit blue light. As a matter of fact, some researchers have found that more than 80% of the blue light which is absorbed through our retinas and skin comes from the light in our workspaces and homes.

It is also believed that blue light from our digital devices produces free radicals, which accelerate our skin aging process with hyperpigmentation as the most evident result. Eczema, brown spots, acne, melasma, sensitivity, and weakening of skin are caused by blue light, according to dermatologists.

Although the amount of blue light emitted by these devices is a lot less than what is being emitted by the sun (the main source of blue light), people have been spending a tremendous amount of time on their electronic devices, and the closeness of the screens to the user’s face has caused these concerning effects.

It gets hard for a person or even a doctor to identify the damage caused by HEV light as it does not burn the skin visibly like UV rays.

“Spending four eight-hour workdays in front of a computer exposes you to the same amount of energy as 20 minutes in the mid-day sun. To put this in perspective, seven minutes of sun exposure at 1 pm is powerful enough to induce immediate tanning, “ says Dr. Murad, a dermatologist and the founder of Murad Skincare Inc. Researchers have also concluded that UV rays are not the only harmful radiation of the light spectrum. Blue light and infrared rays are also causing significant damage to us.

INCREASED SCREEN TIME DURING PANDEMIC

Increased Screen time during Pandemic

Ever since we entered the global pandemic, both scientists and common people have been researching the side effects of blue light or the high energy visible light. We work on our computers, laptops, or smartphones all day long, and we know that the blue light is emitted from these digital devices only. For many years, disturbed sleep patterns and eyesight problems were known to be the side effects of blue light, but over the last years, people are concerned about the potential effects of HEV light on the skin.

The lockdown and home confinement around the globe have made millions, and millions of people stay at home and work from there. And people have been using smartphones, tablets, and laptops to stay in touch with their loved ones. So, people are now more concerned about this situation. Sty light, a global search platform, has noted that there is an increase of 136% Google searches for “blue light skincare” since 2019, and it was at its peak in May 2020 at a 336% increase. 

HOW IS BLUE LIGHT RUINING OUR SKIN? 

We know that scientists are still looking into the effects of blue light on our skin, but it has been proved that it affects comparable to the damage caused by the sun. Scientists have found that pigmentation, redness, and swelling are some common effects of blue light exposure.

These symptoms are seen in individuals with dark skin tones as well. This would mean that HEV light radiation should be a concern for those as well who don’t burn in the sun usually. Blue light also catalyzes the aging process of the skin. As these days we are spending almost all our time in front of screens emitting this radiation, blue light skincare should be prioritized.

WHAT SKINCARE PRODUCT WOULD HELP US FIGHT THE EFFECTS OF BLUE LIGHT?

  •     SPF

SPF

In the markets, sunscreens that block ultraviolet A (UVA) and ultraviolet B (UVB) rays from harming our skin are common. We must find a sunscreen that would protect the skin against all the visible light spectrum. One of the components you should look for while searching for a good SPF is zinc oxide. It is not only good for blocking the harsh visible light but also, it is perfect for everyday use.

  • Hyaluronic Serum

Hyaluronic Serum

One other thing which is great for fighting those signs of blue light exposure is hyaluronic acid. Another benefit of using this acid is that it HYDRATES your skin greatly. The serum can be used just before your favorite moisturizer and sunscreen, and your skin would be hydrated and blue light radiation-free.

  •     Antioxidant Serum

Antioxidant serum

Antioxidant serums help our skin by improving dull complexion, fine lines, and dryness by pushing away free radicals. The work of an antioxidant is to neutralize the oxidative stress caused by light. Vitamins C and E and selenium are great antioxidants.
