If there is one thing people who know me well understand, it’s that I avoid computer work like it owes me money. I will find every other possible thing to do first. I’ll check on the garden. I’ll start a loaf of bread. Bookwork accumulates quietly in the corner for approximately six months until it becomes a situation.

I always thought this was just a personality quirk. A charming one, obviously. Turns out my skin may have been quietly advocating for itself this whole time and I just didn’t know it.

Because here’s what the research is now making very clear: blue light, the kind that pours out of every screen you own, is aging your skin. Quietly. Cumulatively. Without a single warning label.

And I find that deeply rude.

We Finally Got Good at Sunscreen

Let’s take a moment, because we actually deserve it. The collective shift around SPF over the last decade has been real. Women are applying it in the morning. Reapplying it in the afternoon. Choosing moisturizers that already have it built in. We stopped treating sunscreen like something only required at the beach and started treating it like the non-negotiable it actually is.

That is a big deal. Twenty years ago, walking into a spa and asking a client about their daily SPF practice was often met with a blank stare. Now it’s the first thing most of them mention. We did that.

So yes. Take the win.

And then keep reading, because there is a whole other light situation we have been completely ignoring.

Meet the Light You Forgot to Think About

Blue light, sometimes called high-energy visible light or HEV light, sits right at the edge of the UV spectrum. It’s the light emitted by your phone. Your laptop. Your tablet. The LED overhead lighting in your office. The TV you fall asleep watching at 10pm (no judgment, genuinely).

Unlike UV rays, which we’ve spent decades learning to block, blue light sits in the visible spectrum. We can see it. We just didn’t think it was doing anything worth worrying about.

It is.

And the part that makes this so sneaky is that blue light doesn’t come from the sun alone. It comes from the inside of your home. Your office. The palm of your hand at 11pm when you tell yourself you’re just checking one thing. It’s constant. It’s close range. And most of us are bathing in it for the better part of every single day.

What It’s Actually Doing to Your Skin

This is where I need you to stay with me, because it’s worth understanding. Not to scare you. Just because knowing what’s happening means you can actually do something about it.

Blue light hits your skin in two ways, and they work as a team.

The first thing it does: pigmentation.

Your skin actually has its own light receptors, and blue light knows exactly how to find them. When it does, it kicks off a chain reaction that triggers excess melanin production. The research on this is pretty consistent, and here’s the part that surprised even me: for deeper skin tones, the pigmentation blue light triggers can be more persistent and harder to shift than what the sun alone produces.

So those dark spots that don’t quite make sense. The ones that showed up without a lot of sun exposure to explain them. Blue light may have a lot to answer for.

The second thing it does: collagen breakdown.

This is the slower, quieter damage. Blue light creates oxidative stress in the skin, which is a clinical way of saying it generates the kind of low-grade chaos that breaks down your skin’s structural support over time. Study after study has found that it activates enzymes that degrade collagen, reduces your skin’s ability to produce new collagen, and reaches deeper into the skin than UV rays do. It affects elastin too.

Blue light doesn’t announce itself. It just accumulates quietly, the way bookwork does, until one day you look at your skin and something feels different and you genuinely cannot pinpoint why.

That’s the one-two. Pigmentation you can see. Collagen loss you feel later.

And we’ve been sitting in front of it, every single day, largely unprotected.

So What Do We Actually Do

Here is the good news: you don’t have to throw your phone into a field. You just have to be a little more intentional about what you’re putting on your skin before you spend the day in front of a screen.

The blue light filter goes on at the end of your morning routine, right underneath your SPF. Think about what that means. By the time anything from the outside world is attempting to reach your skin, it has to get through your SPF and your blue light protection first. That is a genuinely good situation to be in.

My two favourites for this are the Eminence Daily Defence Tinted SPF and the Shiitake & Ashwagandha Bi-Phase Mist, and I love them together as a pair.

Here’s why the tinted SPF specifically. The iron oxides that give tinted formulas their colour also physically block the wavelengths of blue light that a clear SPF simply doesn’t address. The tint isn’t just cosmetic. It’s doing real protective work. If you’ve ever wondered whether tinted SPF was worth the switch, this is your answer.

Then the mist. And this is important: it belongs on your desk. Not your bathroom counter. Your desk. Because that’s where the blue light is actually coming from. The Shiitake & Ashwagandha Bi-Phase Mist delivers hydration and a hit of antioxidant support every time you use it, right in the middle of the environment that needs it most. A few spritzes in the morning, again after lunch, whenever you think of it. Over makeup, no issue. It’s the kind of thing that takes three seconds and does more than you’d expect.

Together they work as a complete ritual. Morning armour and all-day support. One on your face before you leave the bathroom, one sitting right next to your laptop reminding you that you are tending to yourself even while you’re doing the thing you’d rather not be doing.

Even estheticians have to sit down and do computer work eventually.

Reluctantly.

Still Avoiding It. But Now I’m Covered

I’m not going to pretend I’ve suddenly become someone who loves screen time. I still avoid it. I still choose the garden over the inbox whenever possible. But now when I do finally sit down and open the laptop, I’m covered.

Not out of fear. Not out of panic about what’s happening to my skin in real time. Just because now I know, and knowing means I can tend to this the same way I tend to everything else.

Consistently. Without making it complicated. With the right support already in place.

Your SPF got you this far. Now let it go all the way.
