what is blue light and how can you protect your skin against it?
First of all, what is ‘blue light’?
In scientific terms, blue light is high-energy light with a short wavelength, in the spectrum of visible light.
Where does blue light come from?
While blue light does come naturally from the sun, it poses its biggest threat in the artificial light that comes from our digital devices, like smartphones, TVs and laptops.
It’s thought that most people spend around three hours and 15 minutes a day on their phones. That means three hours and 15 minutes, at least, spent directly exposing the skin on our face to blue light.
What damage could blue light have on my skin?
More research needs to be done into what effects blue light has on skin, but the current understanding is that it weakens the skin’s surface, as well as possibly causing premature ageing and hyperpigmentation.

What can I do to protect my skin against blue light?
Luckily, there are many simple changes you can make to protect your skin against harmful blue light.
Just like natural blue light from the sun, artificial blue light can be combatted using SPF. The Pro Defence+ Anti-Pollution Avocado Day Moisturiser SPF 15 by Able Skincare is a lightweight formula that can be worn under makeup, and will give you a good amount of protection.
Just as you should be putting on your SPF in the morning, a nourishing night cream is also a must. Try Able Skincare’s Hyaluronic Acid Age Recovery Night Cream for intense moisture and an overnight skin restoration.
One of the most obvious things you can do is monitor your screen usage more carefully. If your lifestyle doesn’t allow screen-free days, make sure to adjust the settings on your smartphone and computer to favour yellow light over blue light.
Taking care to pick skincare products which are rich in antioxidants will also help. Able Skincare’s Pro-Activ+ Tightening And Firming Glycolic Serum will not only protect against further damage, but will smooth out any wrinkles already made by blue light exposure.
