Precision Red & Violet Laser Therapy for Pain Relief and Healing
At Foothills Chiropractic, the Erchonia® FX 405 Laser is an advanced low-level laser therapy (LLLT) system designed to precisely target pain, inflammation, and tissue dysfunction—without heat, discomfort, or downtime.
The FX 405 is especially well suited for patients who need gentle, targeted laser care, sensitive areas, or support for both acute and chronic conditions.
What Is the FX 405 Laser?
The FX 405 uses patented laser diode arms to deliver precise doses of therapeutic light directly to affected tissues. This laser system utilizes a combination of:
- Red light (635 nm)
- Violet light (405 nm)
These wavelengths work together to stimulate cellular healing while remaining completely non-thermal—meaning there is no heating, burning, or tissue damage.
During treatment, light energy is absorbed by the cells and used by the mitochondria to increase ATP production, helping the body heal naturally from the inside out.
Why Red and Violet Light Matter
The FX 405’s combination of red and violet wavelengths provides unique therapeutic benefits:
- Red light (635 nm) supports pain relief, circulation, and tissue repair
- Violet light (405 nm) delivers higher energy per photon and enhances pain and inflammation reduction
Research shows that using red and violet wavelengths together produces greater pain relief than either wavelength alone.
In addition, violet light has:
- Anti-bacterial and anti-microbial properties
- The ability to enhance Reactive Oxygen Species (ROS), which play an important role in regulating inflammation and supporting tissue recovery
How FX 405 Laser Therapy Works
FX 405 laser therapy delivers “parcels” of light energy into the cell in a highly efficient way. This energy fuels essential cellular processes and helps:
- Increase ATP (cellular energy)
- Reduce inflammation
- Calm irritated nerves
- Accelerate tissue repair
- Restore normal function
The FX 405 specifically targets Complex IV of the mitochondrial electron transport chain, helping optimize energy production at a critical point in the healing process.
Benefits of FX 405 Laser Therapy
Patients may experience benefits such as:
- Reduced pain and inflammation
- Improved nerve function
- Faster tissue healing
- Reduced muscle tension and trigger point activity
- Improved mobility and function
- Support for post-surgical recovery
Because the laser stimulates the body’s natural healing mechanisms, treatments have no reported adverse side effects.
Conditions Commonly Treated With the FX 405
The FX 405 laser can be used to support healing for a wide range of conditions, including:
- Muscle strains and ligament sprains
- Tendonitis and bursitis
- Neck and back pain
- Sciatica and radiculopathy
- Arthritis and osteoarthritis
- Carpal tunnel syndrome
- Neuropathic pain, including diabetic neuropathy
- Sports injuries and athletic recovery
- Post-surgical pain
- Chronic pain conditions such as fibromyalgia
Comfortable, Non-Invasive Treatment
FX 405 laser therapy is:
- Non-invasive
- Drug-free
- Painless
- No downtime required
Patients remain awake during treatment and typically feel little to no sensation. Most people are able to return to normal activities immediately after their session.
How the FX 405 Fits Into Laser Stacking
The FX 405 is often used on its own for targeted, localized care or stacked with other lasers, such as the Erchonia GVL laser.
When used in a stacked protocol, the FX 405 helps stimulate specific points in the mitochondrial energy pathway while other lasers support deeper or more systemic healing. This coordinated approach allows for more complete cellular activation and more effective results.
Dr. Karan determines whether the FX 405 is used alone or in combination based on your condition, sensitivity, and treatment goals.
Safe, FDA-Cleared Technology
Erchonia lasers are leaders in low-level laser therapy and hold the majority of FDA clearances for LLLT devices. Their technology has been validated through multiple high-quality clinical studies, including randomized, double-blind, placebo-controlled trials.
The FX 405 is FDA-cleared for:
- Temporary relief of nociceptive musculoskeletal pain (using red and violet diodes)
- Adjunctive treatment of post-operative pain (using red diodes)
Personalized Care at Foothills Chiropractic
Laser therapy is most effective when it’s personalized. Dr. Karan carefully evaluates each patient to determine:
- Whether the FX 405 laser is appropriate
- Whether it should be combined with other laser systems
- The ideal treatment plan for your condition
Our goal is always to provide safe, effective, and individualized care that supports long-term healing—not just temporary relief.
