Laser acupuncture, also known as low-level laser therapy (LLLT), is an alternative therapy that utilizes laser energy instead of needles to stimulate traditional acupuncture points. This non-invasive technique is growing in popularity due to being painless, safe, and versatile with minimal side effects. But is it effective, and what does the research say about its safety?
What is Laser Acupuncture?
Laser acupuncture involves using low-intensity lasers to irradiate specific acupuncture points or sites of injury. It works similarly to needle acupuncture by:
- Activating and enhancing biological processes that stimulate healing 1
- Restoring balance and flow of vital energy through meridian channels
- Eliciting analgesic and anti-inflammatory effects
Unlike traditional Chinese acupuncture, laser therapy is applied directly to the skin instead of penetrating it with needles.
Advantages of laser acupuncture include:
- Non-invasive and painless
- Safe for needle-phobic patients
- No risk of infection
- Adjustable doses
- Treats hard-to-reach points
- Wide-ranging therapeutic effects
How Does Laser Acupuncture Work?
The exact mechanisms behind laser acupuncture are only partially understood. Proposed theories as to how LLLT elicits therapeutic effects include:
- Increasing ATP and cellular energy production
- Altering cell membrane permeability
- Stimulating collagen production and tissue repair
- Regulating neurotransmitters and hormones
- Modulating immune response and reducing inflammation
Further high-quality studies are needed to fully elucidate the complex biochemical effects of laser therapy in cell signaling and intercellular communication pathways 2.
Is Laser Acupuncture Effective?
A growing body of research on LLLT demonstrates therapeutic effects comparable to traditional acupuncture for various conditions. Here is a summary of findings from systematic reviews and meta-analyses:
| Condition | Main finding |
|---|---|
| Lateral elbow tendinopathy | Effective in reducing pain and improving function |
| Chronic low back pain | Relieves pain intensity and disability |
| Musculoskeletal pain | Reduces pain symptoms |
| Obesity | Aids modest weight loss and reduces BMI |
While promising, several reviews note limitations of small sample sizes, lack of standardized protocols, and potential publication bias. More high-quality RCTs using rigorous methodology are required to confirm efficacy 3.

Is Laser Acupuncture Safe?
The convenience and non-invasive nature of laser acupuncture adds to its safety profile. But are there any side effects or risks associated with treatment?
Here is a summary of evidence regarding safety from systematic reviews 4:
Minor and Transient Side Effects
- Local skin irritation, redness, itching
- Headaches
- Fatigue
- Nausea
These minor adverse events were temporary and not severe.
Rare and Manageable Risks
- Eye injury if appropriate eye protection not worn
- Pain flares when treating some chronic pain conditions
- Potential for burns if therapy guidelines and parameters not properly followed
No Reports of Serious Adverse Events
Reviews found no major adverse effects like nerve injury or infection from laser acupuncture.
Proper training in laser therapy protocols minimizes risks. Overall laser acupuncture appears very low risk when practicing within the scope of competency.
The Bottom Line
Early research shows promising results for laser acupuncture therapy in various chronic pain and musculoskeletal conditions. Compared to needles, laser stimulation is non-invasive, well-tolerated by patients, and has a favorable safety profile. More high quality studies confirming therapeutic effects are warranted. But current evidence indicates laser acupuncture as an effective complement to conventional treatment for pain and functional impairment.
