&RECOVER Laser for Shoulder Pain: How It Actually Works
Last time we looked at what’s usually behind a sore shoulder — and where laser therapy fits into treating it. Here’s a closer look at how &RECOVER’s Pro and Max devices work, and why the same technology clinics use can be used safely at home.
Clinic-grade power, without the clinic visit
Physiotherapy clinics have used photobiomodulation lasers for pain and recovery for years, typically under staff supervision because of the equipment’s size, cost, and output. &RECOVER’s Pro and Max devices are built around that same underlying technology — but in a lightweight, portable design meant for regular use at home, without booking a clinic appointment every time you need a session.
How the light actually gets to work
The device makes direct contact with the skin over the area you’re treating, and its light energy penetrates through the skin and underlying tissue — reaching well beyond the surface, into the muscle and joint structures beneath.
Once it reaches the cells, that light is absorbed by mitochondria — specifically by an enzyme called cytochrome c oxidase, part of the chain mitochondria use to generate energy. Absorbing the light drives a measurable increase in ATP production: the molecule your cells run on for essentially everything they do, repair included.
In other words, your body isn’t being given energy from the outside so much as being prompted to produce more of its own — a natural response, just switched into a higher gear for a while.
What that extra energy actually does
Cellular metabolism. More ATP means cells have more fuel to work with, so general repair and maintenance processes can run at pace rather than stalling on energy costs.
Collagen production. Fibroblasts — the cells responsible for producing collagen — respond well to this kind of light exposure, which matters for tendons and other connective tissue that heal by rebuilding collagen fibres.
Blood circulation. Photobiomodulation is associated with localised vasodilation, increasing blood flow to the treated area and, with it, the delivery of oxygen and nutrients that repair depends on.
Inflammation. Rather than suppressing the inflammatory response outright, laser therapy appears to help shift it toward resolution faster — part of why pain and stiffness often ease alongside these other effects.
Where this fits for a sore shoulder
None of this replaces the fact that your body already knows how to heal — it’s better thought of as extra help: laser energy giving cells a bit more to work with while they get on with repair they’d be doing anyway, just faster. That’s why laser therapy tends to work best alongside movement-based rehab rather than as a replacement for it, as we covered in our last post.
It’s also why consistency matters more than any single session. Cells need repeated exposure to sustain that lift in ATP production, which is part of why a device’s output and how long you hold it in place both affect how well it works in practice.
