What is Red Light Therapy?
Red light therapy, also known by several other names including photobiomodulation (PBM), low-level laser therapy (LLLT), and cold laser therapy, is a treatment that exposes the body to low levels of red or near-infrared light.
Unlike ultraviolet light which can damage skin cells, these specific wavelengths are considered beneficial and can penetrate different depths of skin tissue without causing harm.
The therapy has actually been around longer than many people realize. The year 2020 marked the 60th anniversary for medical laser treatments like red light therapy, with a substantial body of evidence regarding their potential benefits now available.
Over the decades, what was once considered somewhat fringe science has gained legitimacy, with growing academic and clinical centers in the United States adopting the technology and making it available to patients.
Red light therapy works by delivering specific wavelengths of light (typically between 600 to 1000 nanometers) to skin and tissue.
This particular range includes visible red light and invisible near-infrared light, which can penetrate different depths beneath the skin surface.
The choice of wavelength depends on the intended treatment area and therapeutic goal. What makes this technology particularly appealing is that it doesn’t involve chemicals, invasive procedures, or significant heat, making it generally well-tolerated by most people.
The Science Behind Red Light Therapy
The mechanism behind red light therapy is fascinating and involves cellular energy production. When red or near-infrared light penetrates the skin, it’s absorbed by the mitochondria – the powerhouses of our cells.
This interaction triggers a biochemical effect that strengthens the mitochondria, where the cell’s energy (ATP) is created.
As Dr. Heather Rogers, a dermatologist who supports red light therapy, explains: “When exposed to red and infrared wavelengths, the cells in our bodies absorb energy from the light, become more efficient in their use of oxygen, and are better able to make cell fuel, or ATP. With more ATP, cells become more active and better at doing their jobs”.
This enhanced cellular function leads to several beneficial physiological effects. Research suggests that red light therapy can increase blood flow, reduce inflammation, boost collagen production, and increase the production of fibroblasts, which are essential for skin health.
The therapy also appears to affect cytokines, growth factors, and inflammatory mediators in the body, potentially explaining its wide range of applications.
What’s particularly important to understand is the difference between the types of light used.
- Red light focuses on cell turnover in the dermis and epidermis, addressing skin issues like tone, texture, fine lines, and wrinkles.
- Near-infrared light, which has longer wavelengths, penetrates deeper into the body, targeting circulation and inflammation in deeper tissues.
Many modern red light therapy devices utilize both types of light to provide comprehensive treatment addressing multiple concerns simultaneously.
Key Benefits of Red Light Therapy
The potential benefits of red light therapy span several areas of health and wellness, backed by varying degrees of scientific evidence.
According to studies conducted over the past two decades, red light therapy may help with several conditions and processes.
For skin health, red light therapy has gained significant popularity. It’s believed to promote stronger, healthier skin by stimulating collagen production, which is essential for skin elasticity and reducing the appearance of fine lines and wrinkles.
The therapy also appears to help with skin texture concerns, including acne scars and other textural irregularities.
Dr. Dendy Engelman, a dermatologist, notes that red light therapy can “minimize the appearance of fine lines, wrinkles, acne scars, and other skin texture concerns” while also providing anti-inflammatory properties to reduce puffiness and calm irritated skin”.
Beyond skincare, red light therapy shows promise for pain management and tissue repair. Studies suggest it may promote wound healing and tissue repair while reducing inflammation and chronic joint disorders. This makes it potentially valuable for athletes or anyone dealing with muscle recovery issues.
Perhaps most intriguingly, red light therapy has been investigated for its potential to help cancer patients manage treatment side effects. Research conducted by NASA has shown that red light technology can successfully reduce symptoms experienced by cancer patients, including painful side effects from radiation or chemotherapy.
In one study focusing on oral mucositis (a painful side effect of these treatments), researchers found that 96 percent of patients experienced improvement in pain following red light therapy treatment.
Additional applications being explored include hair growth stimulation, where the therapy may help increase cell turnover, stimulate blood flow and circulation, and create an optimal environment for healthy hair growth.
Types of Red Light Therapy Devices
The market now offers various forms of red light therapy devices, each designed for different uses and treatment areas.
Full-body panels represent the most comprehensive option, designed to treat large areas of the body simultaneously. These panels typically stand upright or can be mounted on a wall, allowing you to stand in front of them for treatment. While effective for addressing multiple areas at once, these tend to be the most expensive option and require dedicated space in your home.
LED face masks have become particularly popular in the skincare world. These mask-shaped devices fit over the face and deliver targeted light therapy to address skin concerns. FoodNourish lists several RLT face masks that don’t cost an arm and a leg to get and they are all FDA-cleared devices that combine red and blue light therapy to address both acne and anti-aging concerns in just three minutes of daily use.
Handheld wands offer flexibility and targeted treatment. Devices like the Solawave Wand combine red light therapy with other technologies such as galvanic current and gentle massage features. These compact devices are travel-friendly and allow for precise application to specific problem areas.

Finally there are the most expensive, suitable for beauty clinics and spas red light therapy beds that although expensive, they illuminate the whole body at once.
How to Choose the Right Device for Your Needs
Selecting the appropriate red light therapy device requires consideration of several factors to ensure you get the most benefit for your specific situation and budget.
- First, identify your primary treatment goals. If you’re mainly concerned with facial skin issues like fine lines or acne, a face-specific device like an LED mask might be most appropriate. For muscle recovery or joint pain, you’ll want a device that can treat larger body areas or penetrate deeper with near-infrared wavelengths.
- Next, consider the device specifications. The most effective red light therapy devices typically use wavelengths between 600-1000 nanometers, with different wavelengths targeting different depths and concerns. Some devices offer a combination of wavelengths for more comprehensive treatment. Look for devices that clearly state their wavelength ranges and intensity levels.
- Budget is naturally an important consideration, as prices vary dramatically. Entry-level handheld devices might start around $100, while professional-grade panels can cost several thousand dollars. The Solawave Wand represents a more affordable option at around $200, while medical-grade devices like the Celluma Home-2Mode LED Therapy system may cost upwards of $800.
- Size and convenience factors should also influence your decision. Consider where you’ll use the device and how much space you have available. Handheld wands require active participation during treatment, while masks and panels allow for more passive sessions. Additionally, think about the time commitment – some devices require just minutes per session, while others may recommend longer treatment periods.
- FDA clearance provides an extra layer of confidence in a device’s safety and efficacy. Several of the popular options on the market, including the Dr. Dennis Gross SpectraLite FaceWare Pro, has received FDA clearance for specific applications.
Safety Considerations and Best Practices
While red light therapy is generally considered safe, understanding proper usage and potential concerns is essential before beginning treatment.
The safety profile of red light therapy is one of its significant advantages – it uses non-ionizing radiation, which means it lacks sufficient energy to cause DNA damage or cell mutations, unlike ionizing radiation such as X-rays or ultraviolet rays.
Red light therapy devices typically generate minimal heat, making them suitable for extended use without burn risks. This distinguishes them from high-intensity laser therapy, which can produce significant heat and potentially cause burns if misused.
Despite this favorable safety profile, some individuals may experience mild side effects. These can include slight skin irritation, temporary redness, or sensitivity in the treated area. These reactions are generally mild and short-lived.
An important safety precaution involves eye protection. It’s essential to shield your eyes from direct exposure to red light therapy, particularly when treating facial areas. The eyes are sensitive to intense light, and prolonged exposure could potentially lead to damage. Using appropriate eye protection, such as goggles or eye patches, is crucial during treatment sessions.
Getting the Most From Your Device
To maximize the benefits of your red light therapy device, consistency is key. Establishing a regular treatment schedule based on the manufacturer’s recommendations will yield the best results. Most protocols suggest daily or every-other-day sessions, typically lasting between 3 to 20 minutes depending on the device and treatment area.
Proper distance and positioning are crucial factors that many users overlook. Each device has an optimal distance from the skin where the light intensity is most effective. Too close might cause unnecessary heat sensation, while too far may reduce the therapy’s effectiveness. The device instructions will specify the ideal distance and positioning for treatment.
Patience is essential when using red light therapy devices. Unlike some treatments that provide immediate results, the benefits of red light therapy often develop gradually over time as cellular processes are enhanced. Many users report noticeable improvements after 4-12 weeks of consistent use, though this varies based on the specific concern being addressed.
Combining red light therapy with complimentary wellness practices may enhance overall results. For instance, proper hydration supports cellular function, while good skin care routines can work synergistically with red light therapy for skin concerns. For those using the therapy for muscle recovery, proper nutrition and adequate rest remain fundamental components of the recovery process.
Record keeping can be valuable for tracking your progress. Taking before and after photos and notes about your concerns, then documenting changes over time, can help you objectively assess the therapy’s effectiveness for your specific needs.
