The problem with blue light and how to minimise our exposure.
These days, when we’re relaxing in the lounge or in our bedroom, it’s pretty much a given we’ll have the television on, or that we’ll spend our time surfing the net on our phone, laptop, or tablet. It can be a lot of fun, but it also exposes us to blue light, which – as studies are increasingly showing – is no great thing for our skin.
Blue light is a type of light that is emitted by electronic devices and LED lights, as well as natural sunlight. It has a short wavelength and high energy that allows it to penetrate even deeper into the skin than ultraviolet radiation (UV) rays.
Exposure to blue light can affect our skin in several ways. Firstly, it can disrupt the skin's natural circadian rhythm, which regulates the production of hormones such as cortisol and melatonin, disrupting our sleep and causing stress. This can lead to skin damage, premature aging, and inflammation.
Secondly, blue light can cause oxidative damage to the skin's cells, leading to the formation of free radicals that damage collagen and elastin fibres in the skin, and - ultimately - contributing to loss of firmness, fine lines, and wrinkles.
Lastly, studies have also shown that blue light can worsen hyperpigmentation, making dark spots and discoloration more visible on the skin.
In other words, blue light can leave our skin feeling kind of… blue.
The good news is, we can help protect ourselves against its worst effects by –
- Using natural skincare products rich in antioxidants. Yep, this is a common theme for us when it comes to suggesting how we can protect our skin against environmental stressors, but that’s because antioxidants are really good at what they do (like really, really good!).
- Wear tinted skincare and/or makeup (like our replenishing Primp N’ Prime, Tinted Moisturiser and Primer) to help create a further barrier between your skin and blue light.
- Shield your skin from blue light by using a screen protector on your devices.
- Eat an antioxidant-rich diet.
