Digital Ageing: Why You Need SPF Even Indoors
In the age of smartphones, laptops, and endless screen time, protecting your skin has never been more complex. We’re used to applying SPF when the sun is shining but what if your biggest source of daily exposure isn’t sunlight, but screen light?
What Is Blue Light?
Blue light, also known as high-energy visible light (HEV), is emitted not only by the sun but also by our digital devices such as phones, tablets, computers, and LED lighting.
While blue light from screens is far less intense than sunlight, research shows that its effects are cumulative. Considering the average adult spends over 10 hours a day in front of screens, this exposure adds up.
How Blue Light Affects Your Skin
Recent dermatological studies reveal that blue light penetrates deeper into the skin than UV rays, reaching the dermal layers where collagen and elastin the foundations of firm, youthful skin are produced.
Prolonged exposure may lead to:
-
Oxidative stress, which damages skin cells and accelerates ageing
-
Collagen breakdown, causing loss of firmness and fine lines
-
Hyperpigmentation, particularly in medium to darker skin tones
-
Disrupted skin barrier, leading to dullness and dryness
This phenomenon is often referred to as “digital ageing.”
Why SPF Matters Indoors
Most people associate SPF with outdoor sun protection, but the truth is that HEV light exposure indoors is constant. That’s why dermatologists recommend using broad-spectrum SPF every morning even if your day is spent under artificial light or in front of a laptop.
Modern SPFs often go beyond UV protection, featuring antioxidants and blue-light filters to shield your skin from these invisible aggressors.
How to Strengthen Your Skin’s Defence
-
Apply SPF daily, even when working from home
-
Look for blue-light protection ingredients like titanium dioxide, iron oxides, or antioxidant-rich actives
-
Add antioxidants such as Vitamin C, Niacinamide, and Hyaluronic Acid to combat oxidative stress
-
Use “night recovery” products to repair and replenish after screen exposure
Final Thoughts
Digital life isn’t going away but premature ageing doesn’t have to be part of it. By understanding blue light and protecting your skin year-round, you can help preserve your glow and safeguard against invisible stressors that come with modern living.
Because in the world of skincare, protection is the new perfection.
