What the HEV? Why too much screen time is bad for our skin

What the HEV? Why too much screen time is bad for our skin

We all know that too much exposure to UV rays from the sun damages our skin.  But what about HEV Light (High Energy Visible Light) - the blue light emitted from our computer screens, iPads, phones and other devices?

Some experts claim that four days in front of a screen is as harmful as 20 minutes of unprotected sun exposure in the middle of the day.

Others say we will soon need to wear ‘facial screens’ when we sit down to work each day.

HEV light has been tentatively linked to macular degeneration of the eyes, but it has now also been shown to stress the skin and cause inflammatory responses as well as degrade collagen and elastin and prevent the skin from carrying out its natural protective, healing and repair processes, thereby leading to what dermatologists are calling “Pollu-Ageing”.

So, what can you do to prevent HEV light damage? 

Clearly, limiting the amount of time you spend on devices is a great first step – we all need to spend less time on our screens anyway, right?

However, it’s also imperative to take care of our skin.

Correct cleansing and exfoliating is the first step. It sets the tone for the rest of your skin care regime to work. Without it, no matter how pricey your potions are, they quite simply can’t penetrate the epidermis and get to the cells where they need to work their magic.

In addition, always wear a broad spectrum, antioxidant-rich, hydrating sunscreen throughout the day.

Consider placing an anti-blue light filter over your computer screen if you are in a job that requires you to look at the screen all day.

Turn your devices to the lowest light possible if you are using them in the evening.

Remember though, Blue light isn’t always bad. In fact, some exposure can be beneficial, when it comes in the right form. LED Light Therapy has been shown to reduce acne as well as smooth skin and soften fine lines and wrinkles.

Blue light therapy targets acne-causing bacteria while also stimulating cells in the body that help with the healing process. Meanwhile, red light therapy stimulates the skin's natural defense mechanisms, which can help to reverse some of the signs of ageing such as uneven skin tone and decreased collagen and elastin.
