Hidradenitis suppurativa is one of those conditions that lingers, hurts, and messes with your day in ways most people don’t understand.
And when creams, antibiotics, or surgeries only go so far, it’s easy to start looking for something – anything – that might actually help.
We’ll unpack whether red light therapy could be a legit tool for managing HS symptoms like inflammation, pain, and slow healing.
- Clinical reports show reduced lesion size and pain within 4-6 weeks of treatment.
- Blue light combined with red light provides antimicrobial benefits against bacterial overgrowth.
- Use 4-5 times weekly during flares, 10-20 minutes per session for best results.
- Works as supportive therapy alongside medications, not a standalone cure for HS.
How Red Light Therapy Works for Hidradenitis Suppurativa
When red and near-infrared light penetrate the skin, they interact with light-sensitive enzymes inside your cells – particularly cytochrome c oxidase in the mitochondria.
This interaction increases ATP (cellular energy), reduces oxidative stress, and triggers healing mechanisms that are often sluggish or impaired in people with HS.
Here’s what RLT can help with:
- Calming inflammation: RLT reduces pro-inflammatory cytokines and supports a more balanced immune response.
- Promoting tissue repair: It helps your skin regenerate faster, reducing the time wounds stay open and painful.
- Easing pain: By improving circulation and modulating pain pathways, RLT offers relief without meds.
- Lowering bacterial load (with blue light): Combining red light with blue light may help address bacteria like Staph and Cutibacterium acnes, which often complicate HS lesions.
- Minimizing scarring: RLT may support better collagen production during healing, which can lead to smoother recovery with fewer long-term marks.
Does Red Light Therapy Help Hidradenitis Suppurativa?
Short answer: It may help – and for some people, it already has.
Clinical case reports suggest that consistent use of red light therapy for hidradenitis suppurativa can reduce lesion size, pain, and recurrence frequency.
In some studies, symptoms improved within 4–6 weeks of regular treatment. While large-scale clinical trials are still limited, the mechanisms behind RLT line up with what HS patients need: inflammation control, wound healing, and immune modulation.
That said, RLT isn’t a cure. It works best as a supportive therapy alongside other HS treatments, including medication, diet changes, and dermatologist-led care.
Key Benefits of Red Light Therapy for HS
Here’s a quick breakdown of why more people with hidradenitis suppurativa are giving RLT a try:
| Benefit | Why It Matters for HS |
|---|---|
|
Anti-inflammatory |
Reduces flare frequency and severity |
|
Pain relief |
Offers drug-free pain reduction |
|
Wound healing |
Speeds up recovery of open lesions |
|
Fewer secondary infections |
Blue light may help control bacterial overgrowth |
|
Lower scarring risk |
Supports proper collagen formation |
|
Non-invasive & safe |
Minimal side effects, even with long-term use |
What About Blue Light Therapy for HS?
Red light therapy gets most of the spotlight, but blue light therapy is sometimes used alongside it for antimicrobial benefits.
Blue light (around 415nm) can help reduce bacterial presence on the skin’s surface, which may lower the risk of secondary infections that worsen HS lesions.
However, blue light doesn’t penetrate deeply, so it’s not enough on its own. That’s why many dermatologists recommend dual-wavelength devices that combine red and blue light, offering both anti-inflammatory and antibacterial support.
How to Use Red Light Therapy for Hidradenitis Suppurativa
If you’re considering RLT as part of your HS routine, here’s what to know about protocols and best practices:
Recommended Treatment Schedule
- Session length: 10–20 minutes per session
- Frequency: 4–5 times per week during flares; 2–3 times weekly for maintenance
- Treatment area: Focus on active lesions and surrounding tissue to calm inflammation beyond the visible nodule
- Duration: Continue for at least 4–6 weeks; benefits build with consistent use
Clinical vs. At-Home Treatment
Professional RLT treatments often use stronger devices with greater tissue penetration, but they come with a higher cost and the inconvenience of clinic visits.
Fortunately, high-quality at-home LED devices, like full-coverage face masks or handheld panels, are becoming more effective and accessible.
Look for devices with:
- Wavelengths in the 630–670nm and 850nm range
- FDA clearance or CE certification
- Safe power density (not too weak, not overpowered)
- Built-in eye protection if treating near the face or neck

Frequently Asked Questions
Does red light therapy cure hidradenitis suppurativa?
No. RLT supports healing and symptom reduction, but HS is a chronic condition. RLT works best when combined with other treatment approaches.
How long does it take to see results?
Most people notice reduced inflammation and pain within 4–6 weeks of consistent treatment.
Can I use it during an active flare?
Yes, and in fact, it’s often most helpful during this time. Use as directed and avoid broken skin unless your device is rated safe for wound areas.
Can it be used with prescription treatments or antibiotics?
Yes. There are no known conflicts, but check with your dermatologist if you’re on light-sensitive medications.
What about light therapy for scarring?
Red light therapy may help reduce scarring by improving collagen remodeling during healing, especially when used consistently during the wound-repair stage.
Conclusion
We’re still learning exactly how red light therapy fits into the broader picture of HS care, but early findings are promising.
Its ability to reduce inflammation, ease pain, and support wound healing makes it a low-risk, potentially high-reward tool in a condition that doesn’t have enough good options.
If you’ve been looking for something gentle and easy to use at home, red light therapy might be worth considering. It’s not a cure, but for many, it’s a meaningful step forward.
Our LED face mask uses targeted red and near-infrared wavelengths to support skin healing and inflammation regulation. Whether you’re dealing with facial HS or just looking for a reliable, hands-free way to stay consistent with light therapy, it’s built to help you care for your skin without disrupting your routine.
