HEV Light and Your Skin 

What is HEV Light? 

High Energy Visible light (blue light) is emitted from the sun and your electronic devices such as computers, televisions and mobile phones.

The sunlight spectrum consists of UV, visible and infrared light. The blue/violet band of this visible spectrum has a particularly high energy level and is known as High Energy Visible Light

 

As you can see from the spectrum above light is measured in wavelengths

Visible light has a wavelength range in the region of 400 to 700nm, with HEV light falling somewhere between the 400-500nm mark.

 

Regardless of exact numbers, the vast amount of damage is caused by unprotected exposure to UVA and UVB light and therefore this is a top priority. Damage from HEV light isn’t far behind and research has proven that HEV Light influences skin condition and can cause skin to age prematurely.

 

HEV Light, just like UVA rays, penetrates into the lower layers of skin (the dermis), with enables HEV light to cause premature ageing and hyperpigmentation. Unlike UVA/UVB rays, HEV is not linked to cancer.

 

The effect HEV has on your skin 

 

Premature Ageing 

HEV light impairs the skin’s natural barrier function. Rather than cause burning or redness, it goes deeper than UV rays, damaging the skin’s collagen, elastin and hyaluronic acid supplies.

HEV Light generates free radicals. These free radicals cause skin cells to produce enzymes that break down the collagen and elastin that give skin its plump, youthful appearance. This process is often called oxidative stress where our body is put under stress as the levels of antioxidants in our body are not high enough to counteract the damaging effect of free radicals.

Ageing is a natural process, but when skin ages prematurely it may start to sag and develop deep wrinkles before its time.

Hyperpigmentation 

HEV Light can induce  hyperpigmentation as it targets the pigment that gives skin, hair, and eyes their color (melanin), which likely plays a role in pigment issues that can occur with over exposure.

 

How to Protect the skin from HEV Light 

Using the correct SPF or suncare products that also have the added protection against HEV light. We have selected our top recommendations that include a full broad spectrum of protection:

NIOD Survival 0 30ml | Available to buy here

This product is designed to work on the free radical damage while you sleep. It is recommend to use on an evening and works targeting the effects of oxygen radicals including the superoxide radical, nitrogen radicals, carbonyl radicals, glycation and advanced glycation end-products (AGE), pollution, smog, stress, infrared and blue light.

 

 

There also other options alongside skincare which can help protect against HEV light such as:

  • Switch your devices to night mode which reduces the blue light in exchange of yellow light which is less harmful to the skin.
  • Computer glasses which are yellow tinted which helps protect against the blue light from your computer screen
  • Install covers that block the blue light from your smartphones, tablets and computer monitors
  • Wear your sunglasses with UV/HEV protection within the lenses

 

Blue Light within Aesthetics 

Blue Light is found within most light therapy devices which we use within the industry and is known for its soothing and calming properties. Light therapy is time controlled and can involve a range of light colours with healing qualities. The blue light is therefore not penetrated for a long period of time to cause the damage that is done with 10 hours a day of screen time for example.
