Could your screen be affecting your skin? Understanding HEV Blue Light.

The blue light that comes off the screens of your phone, tablet and computer is

referred to as HEV (high-energy visible) light. It is part of the visible-spectrum,

meaning that our eyes can see it. It naturally comes from the sun, but it is also

emitted by electronic devices, which has sparked some growing interest on it’s

potential affect on the skin.

Research on the blue and visible light, from the sun, has shown that its interaction

with skin cells can contribute to the production of reactive oxygen species, which

creates oxidative stress (shows up as premature aging). It has also been associated

with increased melanin production and hyperpigmentation.1

It is important to remember that the sun remains, by far, the more significant

source of visible light exposure. There is still limited research on the relatively low

levels of blue light emitted from everyday electronic screens and its relation to skin

aging. More research is needed to understand the long-term effects of screen

exposure.

With that said, the research out there on the impact of visible light, from the sun, is

a reminder that protecting our skin from the full spectrum of environmental light is

an important part of a comprehensive skincare routine.

How can you protect your skin?

Dont’ worry, you don’t have to give up your screen time.

1. Tinted SPF 30 or higher

Using a tinted sunscreen that contains iron oxides has been show to improve

protection against blue light. If you prefer not to use a tinted sunscreen, the

Eminence Ashwhaganda Bi-phase Mist contains iron oxides and can be sprayed

after your moisturizer.

2. Antioxidants

A serum containing antioxidants (vitamin C, E, resveratrol or niacinamide) can help

support your skin’s natural defense against oxidative stress.

3. Barrier Support

Excessive exposure to the sun has an impact on the integrity of your skin barrier. A

weaken barrier can increase sensitivity, texture, inflammation and dryness. To

protect and strengthen your barrier, incorporate products that contain ceramides,

cholesterol and fatty acids. The Eminence Ceramide Repair Balm is a great

moisturizer to repair and support your barrier.
