9 Best Red Light Therapy Devices (+ HSA/FSA Eligible)

Updated: July 20, 2026

🚀 Fast Facts: The 9 Best Red Light Therapy Devices

Red light therapy devices have quickly gained popularity as a non-invasive way to support everything from pain relief and muscle recovery to skin health. But with so many products on the market—and a wide range of claims—it can be difficult to know which devices actually work and whether they're worth your money.

If you have funds in your Health Savings Account (HSA) or Flexible Spending Account (FSA), there's even more to consider. Not all red light therapy devices automatically qualify, and understanding the rules around eligibility, medical necessity, and documentation can save you a lot of out of pocket money if you qualify to expense a red light therapy device through your HSA/FSA.

To choose the best device and see if you might qualify to buy it using your HSA or FSA, we'll cover:

First, we'll start with how red light therapy devices work and the core health benefits, and we'll work towards a practical framework for making a confident and informed purchase.

How does red light therapy work and what are the health benefits?

Before you choose a device or decide how to use your Health Savings Account (HSA) or Flexible Spending Account (FSA), it's important to understand how red light therapy actually works and what it can realistically do for your skin. This foundation helps you separate real, evidence-backed benefits from marketing claims.

In the sections below, you'll learn how red light therapy interacts with your body at a cellular level and the most common health benefits associated with consistent use—especially when tied to specific medical conditions that may qualify for HSA or FSA spending.

How do red light therapy devices work?

Red light therapy devices work by delivering specific wavelengths of red and near-infrared light into your skin, where they interact with your cells to support energy production and healing. This process (known as photobiomodulation) may help reduce inflammation, improve circulation, and promote tissue repair.

At a basic level, these devices use low-level light therapy (LLLT). The light penetrates your skin at different depths, depending on the wavelength, and reaches your cells' mitochondria, which are responsible for producing energy.

Here's a simple breakdown of what happens:

Red light tends to target surface-level concerns like skin health, while near-infrared light penetrates deeper, making it more useful for muscles and joints.

It's important to remember that results depend on consistent use and the specific condition you're targeting. Not all devices are created equal, which is why choosing the right one matters—especially if you plan to use your HSA or FSA.

What are the health benefits of using red light therapy devices?

Red light therapy devices may offer a range of health benefits by supporting your body's natural healing processes at the cellular level. When used consistently, they're commonly associated with reduced inflammation, improved skin health, and relief from certain types of pain.

While results vary by individual and device quality, here are the most widely reported benefits:

  1. Pain and inflammation relief: Red light therapy may help reduce inflammation and ease discomfort in joints and muscles. This is one of the most common reasons people seek an LMN to use HSA or FSA funds.
  2. Improved skin health: Many users report smoother skin, reduced wrinkles and acne, and improved tone. Red light can support collagen production, which plays a key role in skin appearance.
  3. Muscle recovery and performance: Athletes and active individuals often use red light therapy to support faster recovery after workouts by improving circulation and reducing soreness.
  4. Joint support: Near-infrared light may penetrate deeper tissues, making it useful for supporting joint health, especially in areas like knees, shoulders, and back.
  5. Wound healing and tissue repair: Some studies suggest that light therapy can help speed up the healing process for minor wounds and soft tissue injuries.
  6. Circulation support: Improved blood flow can help deliver oxygen and nutrients more efficiently throughout the body, supporting overall recovery.

From an HSA and FSA perspective, these benefits matter because eligibility depends on medical necessity—not general wellness. If you're using red light therapy to treat a specific condition like chronic pain or a diagnosed skin issue, you're more likely to qualify with a Letter of Medical Necessity (LMN).

For example, if your doctor recommends red light therapy for tendonitis, that use case is far more likely to be eligible than using the same device for general skincare.

Is there scientific evidence to support the health benefits of using red light therapy devices?

Red light therapy, also known as photobiomodulation, has been studied across a range of medical and therapeutic applications. While it's not a cure-all, there is a growing body of research suggesting it may support specific health outcomes—especially when used consistently and for targeted conditions.

Here are some key studies and what they show:

  1. Unlocking the Power of Light on the Skin: A Comprehensive Review on Photobiomodulation—This comprehensive review highlights how red light therapy may improve skin tone, reduce wrinkles, and support collagen production by stimulating cellular activity. It explains that light exposure can enhance mitochondrial function, which helps skin cells repair and regenerate more efficiently over time.
  2. Light-based therapies in acne treatment—This research suggests that light therapy can help reduce acne by targeting acne-causing bacteria and decreasing inflammation in the skin. The study also notes that consistent use may help regulate oil production, making it a promising option for managing mild to moderate acne.
  3. The Mechanisms and Efficacy of Photobiomodulation Therapy for Arthritis: A Comprehensive Review—This study found that red and near-infrared light may help reduce pain and improve joint function in people with arthritis. It outlines how photobiomodulation can influence inflammatory pathways and improve circulation, which may contribute to reduced stiffness and better mobility.
  4. The anti-inflammatory effects of photobiomodulation are mediated by cytokines: Evidence from a mouse model of inflammation—Findings show that red light therapy may reduce inflammation by influencing cytokine activity, which plays a key role in the body's immune response. The study provides evidence that light exposure can help regulate inflammatory markers, potentially leading to less swelling and tissue irritation.
  5. The Influence of Phototherapy on Recovery From Exercise-Induced Muscle Damage—This study indicates that light therapy may help reduce muscle soreness and support faster recovery after exercise. It suggests that improved cellular energy production and reduced oxidative stress may help muscles recover more efficiently after strain or injury.

From an HSA and FSA perspective, this research matters because it helps support medical necessity. If your provider recommends red light therapy for a specific condition backed by clinical evidence, you're more likely to qualify for reimbursement with a Letter of Medical Necessity (LMN).

In short, there is credible scientific evidence supporting several uses of red light therapy—especially for skin health, pain, inflammation, and recovery. Next, let's explore the best red light therapy devices available today and how to choose the right one for your needs.

What are the most common health concerns that are treatable with red light therapy devices?
