How red light reaches your shoulder
It helps your shoulder repair from within.
Most treatments work on the surface, they quiet the signal. Red light works underneath the skin, giving the tired cells in your shoulder the energy they need to start rebuilding.
1
The red light supercharges your cells.
Gentle red and infrared light passes painlessly through the skin into the shoulder. Your cells absorb that light the way they use sunlight to produce vitamin D, and turn it into usable cellular energy. With more energy, your cells can repair damage and rebuild tissue faster. This directly stimulates tendon and cartilage repair and supports nerve recovery around the joint.
2
Optimal environment for healing
Peer-reviewed studies prove that red light therapy has anti-inflammatory effects, reduces oxidative stress, improves collagen production and improves blood circulation. This means nutrients can reach the shoulder faster, and waste products are cleared quicker, creating an optimal environment for healing.
3
The result: natural pain relief
Clinical trials report red light therapy measurably reduces shoulder pain intensity and improves range of motion. Follow-ups after 12 months report lasting biological change rather than temporary symptom suppression. Customers who do red light therapy are less dependent on pain killers, and many can stop using them altogether.
"There's a wide gap between 'the pills stopped working' and 'time for shoulder surgery.' For most of my patients with rotator cuff pain and frozen shoulder, medical-grade red light therapy is exactly the kind of non-drug option that belongs in that gap. It works at home, but also particularly well in combination with active rehabilitation."

What red light therapy does underneath the skin
What that means for your shoulder.
Rotator Cuff Injuries & Tendinitis
The rotator cuff is the group of tendons that lifts and rotates your arm, and it's prone to inflammation and small tears from age and overuse, felt as pain reaching overhead or lying on that side at night. Because these tendons sit relatively close to the surface, red light reaches them well, calming the inflammation and helping the tendon repair in an organized way rather than staying chronically irritated.
Frozen Shoulder (Adhesive Capsulitis)
Frozen shoulder is when the capsule around the joint thickens and tightens, slowly stealing your range of motion until simple movements turn painful and stiff. By lowering inflammation and improving circulation to the joint capsule, RLT helps ease the pain and supports the tissue changes needed to gradually loosen the shoulder, especially alongside gentle stretching.
Shoulder Arthritis & Bursitis
Arthritis wears down the cartilage in the shoulder joint, while bursitis inflames the cushioning sac that lets the tendons glide, both producing deep ache, grinding, and swelling. RLT's anti-inflammatory and tissue-repair mechanisms reduce the swelling keeping the joint irritated, stimulate collagen to protect the cartilage that remains, and improve the joint's ability to move without pain.
Post-Injury & Post-Surgical Recovery
After a shoulder injury, a dislocation, or surgery such as a rotator cuff repair, healing depends on cellular energy, blood supply, and controlled inflammation, the three core processes RLT supports. This translates to reduced post-operative swelling, less pain during rehabilitation, and a faster return to reaching, lifting, and sleeping comfortably. A growing number of orthopedic clinics now include photobiomodulation in their shoulder recovery protocols.
Not all red light devices are medical grade
Here's why specs matter for shoulder pain.
The highest power on the market
200mW/cm²
Irradiation power decides how deep the light penetrates. Most devices deliver 80–100 mW/cm². We deliver double that, the difference between a therapeutic dose reaching the deep rotator cuff and shoulder joint and a weak light stopping at the surface.
Cheap LEDs make more heat than light, and heat reduces effectiveness. Medical-grade LEDs deliver precise energy with zero excess heat.
Clinical-grade wavelengths & precision dosing
660 + 850nm
The exact red and near-infrared wavelengths used in the clinical studies that produced positive results for shoulder pain. A controller lets you match clinical dosing protocols to tendon, joint, or capsule.
Research shows dose matters. Our precision controller puts you inside the therapeutic window that produces lasting results.
Wraps snugly around your shoulder. You're in control.
5min setup
The flexible pad molds around the shoulder and upper arm for full coverage of the rotator cuff and joint. If you can wrap an ice pack and press a button, you can use it. No app, no complicated setup, no tricky calibration. Wrap. Press. Heal. (And when your shoulder is better, the same pad works on your knee, hip, back or hands.)
You decide when and where. On the couch, in bed, morning or evening. No appointments or prescriptions needed.

What to expect
An honest roadmap.
Unlike pills, the benefit builds over time. You're not masking the problem, you're supporting repair.
Week 1–2
Cells ramp up
The joint may feel warmer during treatment. Some people notice slightly less morning stiffness as energy production begins to climb.
Week 3–4
Noticeable relief
Many users report a real reduction in pain and improved mobility. Inflammation is beginning to ease at the tissue level.
Month 2–3
Deeper healing
Collagen remodeling, tissue repair, and improved joint function. The cumulative benefit of consistent use becomes clearest here.
Ongoing
It keeps building
The benefits compound the longer you use it, because you're addressing the cause, not chasing the symptom.
An honest comparison
How does it compare to what you're using now?
| NSAIDs Ibuprofen, naproxen |
Physical therapy | Topical creams Voltaren, Biofreeze |
Deep Healing Pad™ | |
|---|---|---|---|---|
| What it does | Masks pain temporarily | Strengthens surrounding muscle | Numbs surface-level pain | Stimulates cellular repair at the source |
| Addresses the cause? | No, pain always returns | Partially, doesn't repair tissue | No, surface relief only | Yes, fuels tissue repair & lowers inflammation |
| Side effects | GI bleeding (4×), kidney & cardiovascular risk | Minimal; can aggravate joints | Skin irritation; surface joints only | None documented in clinical studies |
| Reaches deep joints? | Systemically, with systemic risk | Indirect | No, surface only | Yes |
| Cost | $300–$600/yr OTC | $3,000–$9,000/yr | $200–$500/yr | $269 one-time (50,000+ hrs) |

$269 total is less than three sessions of PT copays, or about $0.37/day over two years.
What keeps most people stuck
3 costly mistakes people make with joint pain.
This isn't a sales pitch. It's what to watch for. Smart, careful people research before they buy.
01
Treating the symptom while the cause gets worse.
NSAIDs mask pain while cartilage keeps degrading underneath. Every month on pills without addressing the joint itself is a month of hidden deterioration you can't feel, until you can.
→ The Cura ProWave Deep Healing Pad™ works at the cellular level, where repair actually happens.
02
Choosing a device by price instead of specs.
Budget red light devices deliver 80–100 mW/cm². Not enough power to reach deep joints like knees, hips, and shoulders. You end up with an expensive nightlight instead of a therapeutic device.
→ At 200 mW/cm², our light is strong enough to reach the joint, not stop at the skin.
03
Waiting until the pain is unbearable.
Osteoarthritis is progressive. The earlier you support your body's repair process, the more there is to work with. Waiting until you "really need it" means the joint has already deteriorated further.
→ The best time to start supporting repair is before the joint loses more ground.
Staying on the same path can feel safe. But look at what "safe" actually means: continued NSAID use (which raises GI bleeding risk 4× and chronic kidney disease risk by 46% in older adults), progressive cartilage loss, and a condition that only moves one direction without intervention. The riskiest choice is to do nothing, because when you do that, time will work against you.
Questions, answered honestly
Before you order.
We built this for skeptics. For people who've been burned by empty promises, who check the research and need to understand why something works. If that sounds like you, these are the questions you're probably asking.
Can a light really heal my chronic joint pain?▼
That skepticism is a sign of intelligence, not a reason to dismiss the evidence. Red light therapy has been studied in over 5,000 peer-reviewed papers. A meta-analysis of 22 randomized trials found it significantly reduced knee osteoarthritis pain when properly dosed. Because we built this for people who need proof, not promises, every device is backed by a 60-day money-back guarantee. Try it. See the research for yourself here. If it doesn't work, you get every dollar back.
Aren't there cheaper devices on the market?▼
Yes, there are, but they are not medical grade. Budget devices deliver 80–100 mW/cm², while the Cura ProWave Deep Healing Pad™ delivers 200 mW/cm². That's double the power, and determines whether the light penetrates to the joint or stops at the skin. For deep structures like knees and shoulders, that's the difference between a therapeutic dose and an expensive nightlight. We also use medical-grade triple-chip LEDs; many cheap devices use LEDs that generate excess heat, which actually reduces effectiveness.
How quickly will I feel relief?▼
If something promises instant results for chronic joint pain, it's numbing the problem, not fixing it. This works differently: it supports your cells' ability to repair damage, reduce inflammation, and rebuild tissue. Most users feel initial changes within 2–4 weeks, with results building over time. The key difference is that relief gets better the longer you use it, because you're addressing the cause. Unfortunately, there is no shortcut. Our body works on a cellular timeline. Damage that has built over years can't be repaired instantly without surgical intervention.
Why hasn't my doctor mentioned this?▼
Most doctors weren't trained in photobiomodulation, but the evidence is gaining institutional recognition. The AMA approved a billing code for it in 2024. We encourage you to share the research with your doctor. And with a 60-day guarantee, there's zero risk in trying while you do your own research.
I'm struggling to make ends meet. Can I get a discount?▼
Yes. First-time customers get $15 OFF their first order. Just sign up to our newsletter at the bottom of our website and we'll email you a discount code. We also accept payments in installments, as well as FSA/HSA cards for additional savings using pre-tax dollars.
The reality is, you're paying much more for your pain already:
- With medications (~$960/year), physical therapy sessions (~$150/session) & regular clinic visits.
- With missed work days, because you couldn't stand long enough to do your job.
- With your health, because NSAIDs and painkillers wreak havoc on your organs.
- With your freedom, because the pain limits your mobility.
- With missed memories, because you were too uncomfortable to go to your grandson's baseball game.
You're already paying. The question is whether you're paying to get better, or whether you keep paying to stay the same.
What is the maximum waist size?▼
The largest suitable waist size is 34.6". For bigger waist sizes, an additional velcro strap is needed.
I have metal implants. Can I still use this device?▼
Since the Cura ProWave Deep Healing Pad™ is a medical device, we have a legal responsibility to ask people with metal implants to seek advice from their doctor, as we're not able to assess each customer's unique situation. In general, however, red light therapy is completely safe to use on areas containing surgical implants, pacemakers, or titanium screws.
