Red Light Therapy for Wrinkles: What's Actually Happening Under Your Skin
There's a moment, usually in February/March, usually under terrible bathroom lighting, when your face says something to you that no amount of optimism can quite soften.
It's not just tired. It's not just dry. It's something more like... the accumulated cost of another Norwegian winter living itself out on your face. Fine lines that weren't there in October. A greyness that no amount of water and early nights seems to shift. A quality to the skin that a friend of mine once described as "like parchment that's been left near a radiator." Brutal, honestly, but not entirely inaccurate.
If you are a man, maybe there is a moisturiser around, maybe not - men are different. If you are are a women, it might be different. Your first instinct is to reach for something in a tube. Some cream with a name that sounds vaguely scientific and costs enough to make you believe it might work. I'm not here to mock that instinct. Bathroom lighting is harsh and I have had that same thought! But after years of going deeper into the actual biology of what ageing skin is doing at a cellular level, I can tell you that the cream is addressing approximately the wrong problem entirely.
This is the thing the skincare industry has quietly built an empire on: the idea that skin ageing is a surface problem. It isn't. It's a mitochondrial problem. And that distinction matters more than most people realise. It's a mitochondrial problem that is, at least in part, caused by your light and EMF exposure.
Your Skin Cells Have an Energy Crisis
Let me paint you a picture that has nothing to do with skin, and then we'll bring it back round.
Imagine a factory that's been steadily cutting its power supply for several months. The machines are all still there. The workers know what they're supposed to do. But with reduced electricity, everything slows down. Quality control slips. Repairs that used to happen overnight now take a week. Output drops. The building starts to look... worn. I mean, in a very real sense, we have seen it happen in Norway with budget cuts... your body is also undergoing budget cuts.
That's what's happening inside your skin cells over a Norwegian winter.
The mitochondria in your skin cells, particularly in the fibroblasts that produce collagen and elastin, run on ATP. Adenosine triphosphate. The cellular currency of energy. For those fibroblasts to produce the structural proteins that keep your skin firm, bouncy, and plump, they need a steady supply of that energy currency. When the supply drops, collagen production slows. Elastin synthesis slows. DNA repair slows. The whole maintenance operation starts running on a skeleton crew.
Now here's the part that most skincare conversations completely skip over: one of the primary inputs to mitochondrial function in skin cells is light. Specifically, red and near-infrared light in the 600nm range up to 800nm range.
Your skin cells contain chromophores, light-absorbing molecules, that are specifically tuned to these wavelengths. An important one is cytochrome c oxidase, an enzyme in your mitochondrial electron transport chain. When it absorbs red and near-infrared photons, electron transport improves. ATP production goes up. Your cells have more energy to work with.
In summer, this happens naturally. Sunlight contains abundant red and near-infrared wavelengths. Your skin is bathed in them every time you're outside. But in a Norwegian winter? You go from eight-plus hours of full-spectrum light to months of indoor LED lighting that contains almost none of these regenerative wavelengths. Your skin cells are essentially running a factory with the power half cut.
That's not a metaphor. That's the mechanism. And it's why no amount of topical moisturiser fully compensates for what's happening deeper down.
The EZ Water Angle (This One Genuinely Blew My Mind back in 2024)
I want to talk about water for a minute, because there's a layer to this that most people have never encountered and it changed how I think about skin health entirely.
Dr. Gerald Pollack, a biophysicist at the University of Washington, has spent decades studying what he calls the fourth phase of water. Most of us learned in school that water exists in three states: solid, liquid, gas. But Pollack's research shows that water at biological interfaces, at cell membranes, at protein surfaces, forms a structured, gel-like phase called exclusion zone water, or EZ water. It's more ordered than bulk liquid water. It carries a negative charge. And it's essential to how cells actually function.
EZ water in your skin cells acts as a kind of cellular battery. It maintains the voltage across cell membranes that drives nutrient transport, waste removal, and protein folding. Healthy skin cells have healthy EZ water zones. Compromised EZ water means compromised cellular function across the board.
And here's where it connects back to light: infrared wavelengths, particularly in the 800nm range and much longer, actively build and maintain EZ water zones. This is part of why natural sunlight is so extraordinarily good for biological systems, it contains infrared in abundance. And it's part of why replacing sunlight with standard LED lighting for months leaves your cells in a kind of electrical deficit.
When someone asks me why their expensive moisturiser isn't working, part of the answer is this: moisturiser puts bulk water on the surface. It doesn't rebuild the structured water zones inside your cells that are actually driving the failure of repair processes. You're filling the swimming pool while the pump motor is broken.
What Collagen Production Actually Requires
Right. Let's be specific about the rynker (wrinkles) piece, because that's what everyone actually wants to know about.
Collagen is a structural protein. It's what gives your skin its tensile strength, its firmness, its resistance to sagging. Elastin is what allows it to spring back when you poke it. Both are produced by fibroblasts, cells that live in the dermis, the deeper layer of your skin beneath the epidermis.
Fibroblasts are metabolically active cells. They consume a lot of ATP to synthesise and secrete collagen. The process is genuinely complex: collagen has to be assembled from amino acids, folded correctly, transported to the cell surface, secreted, and then crosslinked in the extracellular matrix. Every step in that chain requires energy and functional cellular machinery.
When mitochondrial function is reduced, as it is in the light-starved environment of Norwegian winter, fibroblasts don't suddenly start making bad collagen. They just make less of it. And less collagen, combined with ongoing breakdown from normal metabolic processes, means the net balance tips toward loss. Skin gets thinner. Fine lines become more visible. Elasticity reduces.
Red light therapy, used properly, addresses this at the source. Studies have demonstrated increases in collagen density in the dermis after consistent red light exposure. Reduced visibility of periorbital fine lines (the ones around your eyes). Improved skin elasticity as measured by dermatoscopy. Faster wound healing times, which is really just a proxy measure for the overall efficiency of cellular repair.
Professor Michael Hamblin at Harvard has spent much of his career studying exactly these mechanisms. His work, and the work of researchers like Dr. Alexander Wunsch in photobiology, has built a solid, peer-reviewed framework for understanding how specific wavelengths interact with specific biological targets. This isn't wellness industry wishful thinking. It's biochemistry.
But Here's What the Instagram Posts Don't Tell You
I have always been honest, and I always will be. There are more and more cowboys out there now in 2026 than ever before. I want to be straight with you, because I think people in this space often aren't - Red light therapy and skin health is minefield.
Red light therapy is not fast. It is not dramatic. And it absolutely does not overcome everything else that influences how your skin ages.
If you're sleeping four hours a night, eating mostly processed food, chronically stressed, and spending all day under harsh fluorescent lighting, red light therapy is going to make a modest dent in a large problem. It's not a substitute for the foundations. It's a targeted tool that works best when you're also getting the basics right.
What it does well: supporting the cellular processes that keep your skin maintaining and repairing itself in an environment that otherwise starves those processes of the inputs they need.
What it doesn't do: reverse decades of accumulated damage overnight, compensate entirely for poor diet or sleep, or work at all if your device is one of those cheap RGB LED contraptions that blends colours to look red without delivering therapeutically meaningful wavelengths. That last point is worth dwelling on for a moment.
A lot of devices on the market, particularly at the cheaper end, use RGB LED chips. These blend red, green, and blue to produce a reddish glow, exactly like your TV screen does when it shows red. You will see these often marketed as 7 wavelengths or something like that. The light looks red. But cytochrome c oxidase doesn't care what the light looks like. It responds to specific wavelengths. For example 660nm is 660nm. A blend of RGB that produces a reddish colour is not 660nm. The biological response is entirely different.
This is why I'm particular about what I stock. The panels and portable devices in my Restore collection use properly specified narrowband LEDs at documented therapeutic wavelengths. When I say 630nm, or 660nm or perhaps 830nm or 850nm, that's what it delivers, measured, not approximated. To make sure, I test them with a spectrometer. I sent back some items recently that weren't as described - most companies don't test and you don't even know if the red light therapy you order is the red lgiht therapy mask or panel that you are getting.
A Practical Word on Protocol
I use red light on my face and neck a few mornings/evenings per week. Ten to fifteen minutes, close enough to the panel that I'm getting meaningful irradiance or with a mask. I've done it consistently for years now, and the results have been gradual, cumulative, and real. Not Instagram-transformation real. Just "my skin holds up better through Norwegian winter than it used to" real.
For portable use, a properly specified mask delivers light directly against the skin, which compensates for lower total power output. Don't believe the people selling you masks at 170mw/cm2 - why would you even want that high of an irradiance for your skin at that distance? Answer - you wouldn't!!! The advantage of a mask is convenience: you can use it while reading, while having your morning coffee, while doing absolutely anything that doesn't require you to look at something in particular. Consistency trumps perfection every time.
Morning sessions work well for signalling daytime to skin cells and boosting mitochondrial function at the start of the day. Evening sessions support repair processes during sleep. If I had to pick one: morning, because I find it sets something up for the rest of the day that I notice when I miss it.
Six weeks of consistent use before you evaluate. That's my honest timeline. Some people see changes faster, particularly in skin tone and colour and glow and blood flow. The structural changes, the ones involving actual collagen remodelling, take longer. Be patient with the process.
The Bigger Picture
Here's the thing I keep coming back to: we've built a modern indoor environment in Norway that is, in a very literal sense, light deficient. Not in the "you need more vitamin D" sense that the mainstream health conversation occasionally acknowledges. But light deficient in the specific wavelengths that drive cellular repair, mitochondrial function, and the biological maintenance of the tissues we're walking around in.
Then we spend a fortune on topical products trying to patch the surface results of that cellular deficiency from the outside.
It's not that those products are useless. Some of them help. But they're addressing the symptom while the underlying cause, a few months of biological signal starvation, continues unaddressed.
Red light therapy, at its best, is restoring a signal that evolution spent hundreds of thousands of years expecting your skin cells to receive every single day. Not adding something artificial. Replacing something natural that modern life removed.
That's not hype. That's just physics and biology, doing what they've always done.
