SPF Indoors: What You Don’t Know Can Age You
Posted on by AdminDo I really need sunscreen if I’m just working from home?
I hear this all the time, especially from clients who spend most of their day on a computer or sitting by a window. And I get it—when you’re not lounging poolside or hiking a sunny trail, SPF can feel like overkill. But here’s the truth: your skin is still vulnerable—even indoors.
Let’s talk about why.
Screen Time & Blue Light (HEV): The Invisible Skin Agers
Laptops, phones, tablets—even your big beautiful monitor setup—they all emit blue light, also known as HEV (High Energy Visible) light. While HEV light doesn’t burn like UV rays, studies show it can penetrate deep into the skin and contribute to:
- Premature aging
- Hyperpigmentation (especially melasma)
Inflammation and dullness
So, if you’re clocking 6–10 hours a day on a screen (like most of us), it’s time to start thinking of SPF as your digital skin armour.
What should you look for in a sunscreen?
Choose one that offers blue light protection or contains iron oxides—a powerhouse ingredient shown to block HEV light. Added antioxidants are a bonus to fight off oxidative stress caused by screen exposure.
That Sunny Spot by the Window Isn’t So Safe
Let’s bust another myth: “I’m inside, so the sun can’t get me.”
Here’s the deal:
- Glass blocks UVB rays (the kind that cause burns)
- But not UVA rays, which go deeper and are responsible for wrinkles, sagging, and sunspots
So yes, your skin is still getting UV exposure through windows. That sunny spot in your kitchen, your office window view, or even your morning drive to work—it all adds up. I’ve seen many clients with one side of their face more aged than the other, simply from sitting near a window every day. Sunscreen is your best defense.
Kim’s Top SPF Pick for Screen Lovers & Window Sitters
We carry a range of sunscreen options at Rejuva, but for indoor protection, this is my top pick:
ZO Daily Sheer Broad-Spectrum SPF 50 is lightweight, matte, and water/sweat-resistant—but what I love most is its inclusion of antioxidants and DNA repair enzymes to help mitigate damage from both UV and HEV light. It’s sheer, fast-absorbing, and great for daily indoor wear. “I recommend this to clients who sit by windows or use screens all day. It’s breathable but powerful.”
Not sure which sunscreen fits your routine? Pop in and ask—we’ll help you find one you’ll actually want to wear every day.
