MLS laser therapy is an FDA-cleared, non-invasive treatment that uses synchronized dual-wavelength light to reduce pain and inflammation and stimulate tissue repair at the cellular level. It works by delivering two specific wavelengths of infrared light simultaneously: one targets inflammation and swelling, the other stimulates cellular energy production, specifically ATP, which is the fuel cells need to repair and regenerate. There are no incisions, no medication, and no recovery time. Most sessions take between 8 and 15 minutes.
For people who have spent months cycling through anti-inflammatories, cortisone shots, and rest without lasting improvement, MLS laser therapy offers a different approach. Rather than blocking pain signals temporarily, it works to change the tissue environment itself, giving the body what it needs to move from chronic irritation toward genuine recovery. At Pain Doctors Medical, with locations in Brooklyn, NY; Clifton, NJ; Newark, NJ; and Perth Amboy, NJ, Dr. Ilana Etelzon typically offers MLS laser therapy as part of a comprehensive regenerative medicine program, most often paired with PRP injections, because the two treatments work together in ways that neither achieves as consistently on its own.
Why MLS Laser Therapy Is Not What Most People Expect
When people hear the word laser, they tend to think of heat. A surgical laser cuts. A cosmetic laser resurfaces. But MLS laser therapy belongs to a different category entirely.
MLS stands for Multiwave Locked System. The technology uses two synchronized wavelengths of light, each doing a distinct job. One wavelength targets inflammation, working to reduce swelling and calm the chemical signals that keep tissue in a reactive state. The other penetrates more deeply to stimulate cellular repair. Together, they create an effect that neither wavelength could produce alone.
The critical distinction is what this light does once it reaches the tissue. Rather than generating heat to stimulate surface circulation, the way a heating pad does, MLS laser energy is absorbed directly by cells. Specifically, it targets the mitochondria, the structures inside each cell responsible for producing ATP, which is the cellular fuel that drives repair, regeneration, and function. When mitochondria are given that light stimulus, they produce more ATP. More ATP means more energy available for healing. The cell is not being tricked into feeling better; it is being given what it needs to actually repair.
The Problem MLS Laser Therapy Is Actually Solving
Chronic pain is rarely just pain. It is almost always a sign that tissue is stuck in a dysfunctional state: inflamed, poorly perfused, structurally compromised, and unable to complete a normal healing cycle. Dr. Etelzon describes this as a tissue environment problem, and it is central to how she approaches treatment.
“Pain is often a signal that tissue is irritated, inflamed, overloaded, or not healing properly,” Dr. Etelzon explains. “If we only numb the pain temporarily without improving the health of the tissue, the problem often keeps coming back.”
In chronic tendon injuries, joint irritation, soft tissue inflammation, and overuse syndromes, damaged tissue can enter a cycle that is difficult to escape on its own. Persistent inflammation reduces local circulation. Poor circulation limits the delivery of oxygen and nutrients. Without those resources, the tissue cannot repair itself, which leads to ongoing microdamage, increased sensitivity, and eventually a failed healing response. The tissue is not healing; it is simply surviving.
MLS laser therapy is designed to intervene in that cycle. By improving microcirculation, increasing cellular energy production, reducing inflammatory mediators, and supporting lymphatic drainage, it attempts to shift the tissue out of chronic dysfunction and into an environment where recovery is possible.
Who Benefits Most from MLS Laser Therapy
Dr. Etelzon finds MLS laser therapy most valuable when the underlying problem involves irritated, overworked, or slowly healing tissue. Muscles, tendons, ligaments, joints, and nerves all respond to treatment, making it relevant across a wide range of pain presentations.
Patients who have been managing plantar fasciitis for months without real improvement often respond well. So do those dealing with chronic knee or shoulder irritation, tendinopathy that has not resolved with rest or physical therapy, and joint inflammation that keeps flaring despite anti-inflammatory medications. Nerve-related discomfort, including peripheral neuropathy, is another area where MLS therapy has shown benefit, in part because of its effect on improving circulation and reducing the inflammatory environment around nerve tissue.
The patients who tend to arrive at Pain Doctors Medical’s Brooklyn, Clifton, Newark, and Perth Amboy locations having exhausted conventional options are often the ones who benefit most. Not because MLS laser therapy is a last resort, but because their conditions are precisely the kind of chronic, slow-to-heal tissue problems the treatment is built to address.
What Treatment Looks Like and When Results Begin
A session is straightforward. The patient is positioned comfortably while a handheld device moves over the treatment area, delivering laser energy through the skin without cutting, without needles, and without any meaningful discomfort. Most people describe feeling mild warmth or a gentle tingling sensation. Sessions are brief, typically lasting between eight and thirty minutes depending on the area being treated, and there is no recovery period afterward.
How quickly a patient notices a difference depends on the nature and duration of the condition.
“Some patients feel relief after one to three treatments, while others notice more gradual improvement over several weeks because the effects are cumulative,” Dr. Etelzon notes.
Acute flare-ups or recent injuries often respond after four to six sessions. Chronic tendon or joint conditions commonly require six to twelve. Longstanding degenerative problems may need a longer initial course and periodic maintenance treatments to sustain the improvement.
Why Cortisone Shots and Medications Leave the Underlying Problem Untouched
Patients who have been cycling through cortisone injections and anti-inflammatory medications for months or years without lasting relief are often understandably skeptical that anything short of surgery could help. Dr. Etelzon takes that skepticism seriously, because the treatments they have tried were not ineffective by accident. They are simply designed to do something different.
Cortisone can reduce inflammation quickly, but repeated use does not improve the structural quality of the tissue. Anti-inflammatory medications may blunt symptoms temporarily, but they do not stimulate healing. Rest alone can calm reactive tissue in the short term, but chronically injured tissue that is not actively recovering often becomes weaker and stiffer over time. The underlying cycle of inflammation, poor circulation, and failed repair continues.
“Instead of only asking how we block the pain, the approach becomes: why is the tissue remaining irritated or failing to recover?” Dr. Etelzon explains.
MLS laser therapy is positioned as an answer to that second question. It is not masking a signal; it is attempting to address the reason the signal keeps firing.
MLS Laser Therapy as Part of a Comprehensive Regenerative Program
At Pain Doctors Medical, MLS laser therapy is rarely prescribed in isolation. Dr. Etelzon’s approach is to offer it as part of a comprehensive regenerative program, most commonly paired with PRP injections and, where appropriate, bone marrow concentrate. This is a deliberate clinical decision, not simply a matter of layering treatments. Each component plays a defined role, and they are sequenced with that in mind.
PRP injections deliver concentrated growth factors and biologic signals directly to damaged tissue, prompting the body to initiate a repair response. But the environment surrounding that tissue still matters. Many chronic injuries present with poor circulation, accumulated inflammation, cellular dysfunction, and scar tissue that has built up over time. That environment can limit how well the tissue responds to a regenerative injection, regardless of what the injection delivers.
MLS laser therapy addresses that surrounding environment. Used before or after an injection, it helps improve microcirculation, calm reactive tissue, increase cellular energy production, and support the lymphatic drainage that clears inflammatory debris.
“The injection provides the biologic material and healing signals, while the MLS laser helps create a healthier environment for the tissue to respond and recover,” Dr. Etelzon explains.
When shockwave therapy is also part of the program, it serves a mechanical stimulation role, prompting the tissue to respond to physical stress. MLS laser therapy then supports the recovery phase between shockwave sessions, helping tissue calm down and process the stimulus more efficiently. The result is a program in which each treatment reinforces the others rather than working in parallel.
For patients who want to address the root cause of their pain rather than manage it indefinitely, this structured program approach is where the most meaningful and durable results are typically found.
A Different Starting Point for Chronic Pain
MLS laser therapy is not a cure for every condition, and Dr. Etelzon does not present it as one. But for patients whose tissue is stuck in a state of chronic dysfunction, it offers something that medications and cortisone injections typically cannot: an attempt to change the underlying tissue environment rather than simply respond to the symptom it is producing.
At Pain Doctors Medical’s locations in Brooklyn, NY; Clifton, NJ; Newark, NJ; and Perth Amboy, NJ, it is part of a regenerative medicine practice built on the belief that the body has more capacity to heal than conventional pain management typically gives it credit for. For patients who have run out of conventional options without running out of hope, that starting point makes a meaningful difference.
