Are computer screens responsible for your skin ageing? Yes! But how? Let’s find out.
Have you ever heard about HEVL or high-energy visible light (commonly known as Blue Light) that is emitted by our technological devices?
If not, then you are at the right place because we are going to unravel the mysteries of ageing through your computer screen and the precautions we can take to minimize its damages.
High-energy Visible Light (HEVL) is a high-frequency light in the range of 400 to 500 nm (violet/blue band) from in the visible spectrum if light. High Energy Visible Light refers to the higher-frequency, shorter wavelengths, of light in the violet-blue band in the visible spectrum.
No doubt that HEV is present in daylight, but it is also emitted by fluorescent lighting and LEDs, including Smartphone, TV screens, tablets, and computers. This blue light spectrum emitted by our new technological device’s screen has become a major concern in the beauty industry. Even though there is no tangible evidence of HEV causing skin cancer it has become a major concern. Every dermatologist is doing their research on HEVL, trying to find the best way to minimize its damage by balancing the emission of the blue-violet light.
Harmful effects of HEVL
The effects of HEV are as harmful as the UVA and UVB rays combined together. Here are some of the damages that the blue light could cause:
- Skin unevenness
- Premature ageing
- Impaired barrier function
- Age-related macular degeneration (AMD)
- Sleep disorder
- Photoreceptor cell death
HEVL and Skin Ageing
High-energy Visible Light stimulates the matrix metalloproteinases (MMP) of the skin that lead to premature wrinkle formation, ageing and also increases skin fragility. The effects of HEVL are debatable given how much time you spend in front of the screen. The research is still running on HEVL and there has been no concrete say on if the visible light causes permanent damage to our skin. Yet precaution is always better than cure.
The blue light is certainly present in the sunlight as well as the screen light, a given fact. It would be considered wise to use sunscreen (SPF15 and above) at all times, even when you are staying at home, indoor, watching television, using your computer/laptop or simply using your phone in bed before dropping off to sleep. Considering that your job requires you to sit in front of the computer screen at a stretch for a long period of time, use sunscreen or products that claim to have HEV light blocking properties. If you haven’t heard of products having such claims, you soon will.
It is said that visible light worsens skin pigmentation for darker skin types, such as melasma around the forehead and eye; a study also found that blue light does produce more hyper-pigmentation than UVB.
How to deal with it?
There is no escape from the HEVL unless you starve yourself of the digital technological world. Still, the visible light from the sun will hunt you down. So how do you prevent premature ageing from the visible light?
Use HEVL SPF50 Face Cream
There are products that offers 3 spectrum protections that is, protection against UVA, UVB, and HEVL. The Liposhield HEV present in these creams is one of the new generation of SPF ingredients to specifically provide skin protection against HEVL rays. Liposhield HEV is a synthetic melanin, a wonder ingredient which is made from a vegetable derived tyrosine (amino acid that helps in the production of melanin in the skin) which is designed specifically to absorb HEVL rays
Antioxidant Packed Face Serum
Use face serum packed with antioxidants such as Vitamin C, Phloretin, and Ferulic Acid which will only prevent free radical damage during the day but will protect the skin against the Blue Light emitted from digital devices.
Shine Down That Light
Simple steps like turning down the brightness of your devices and softening the blue tone that is emitted from the screen will help reduce the effect of HEVL. Long continuous glaring at your device’s screen is taxing for your skin cell and your eyes.
Avoid using Social Media on a Sunny Afternoon.
This goes out to all the “selfie ritualists”. If you are one of those who cannot go without taking a selfie because you have got the perfect lighting outdoor. Keep your phone in your pocket. The HEVL emitted from the screen along with the UV rays reflected off the screen of your device makes your skin extremely susceptible to skin damage as the skin is exposed to a higher level of collagen-destroying substance than usual.
Blue Light Reduction Filter
There are these special glasses on the market that helps reduce the harmful effects of blue light. It has an innovative filtering blue light blocking technology, which reduces exposure to blue light while you’re working, gaming, checking social media or studying on your computer.
