Are you always addicted to your smartphone or laptop? You may end up endangering your skin’s health as well as straining your eyes. Are you wondering how?
Blue light generated by electronic gadgets has been shown to cause long-term skin harm. However, you may mitigate its effects by adopting healthy behaviors and caring for your skin.
Let’s look more closely at the blue light and how you can protect your skin from its damaging effects.
What Exactly Is Blue Light?
As we all know, sunlight is divided into several colors such as violet, indigo, blue, green, yellow, orange, and red. Each light in the visible light spectrum has a unique wavelength and impact. Blue light, also known as High Energy Visible light (HEV), is a kind of visible light with shorter but higher energy wavelengths ranging from 380 to 500 nanometers. During the day, blue light is useful since it improves your concentration, memory, and general mood. However, its effects on your health and skin might be severe after sunset or if you are exposed to it for an extended period of time.
Although the effects of blue light generated by electronic device screens are less severe than those of sunlight, there is growing worried about the long-term impacts due to closeness to the screen and exposure time spent staring at the screen.
What Effect Does Blue Light Have on Your Skin?
You spend over half of your day interacting with media on screen. But what you may not understand is that screen time affects your health in a variety of ways, ranging from interfering with your sleep, cognition, and metabolism to less obvious effects such as damaging your skin. Yes, you read that correctly. Blue light can also be harmful to your skin. It can cause serious harm to your skin cells, premature aging, and pigmentation.
According to one study, long-term exposure to high-level blue light can have comparable effects to UV light exposure. This is due to the fact that blue light creates the same sort of free radicals as UV radiation, which causes skin damage such as wrinkles and discoloration.
Another research found that when your skin is exposed to blue light for an extended length of time, it produces twice as much melanin as when it is exposed to UVA and UVB rays. Increased melanin can cause dark patches, premature ageing, melasma, and other skin problems. Furthermore, when your skin is exposed to blue light and then separately to UVA, it develops greater swelling and redness.
According to the scientific findings mentioned above, blue light is damaging to your skin and can cause cellular damage. Blue light, because it may penetrate deeper into your skin layers, destroys the epidermal barrier, resulting in hyperpigmentation. It can also induce skin oxidative stress. As a result, your skin will lose firmness.
