The Benefits of Red Light Therapy: What the FDA and Medical Field Say
Red light therapy, also known as photobiomodulation or low-level light therapy (LLLT), has become one of the most talked-about non-invasive treatments in health and wellness. At L.A. Health Solutions, we believe in evidence-based therapies that improve the lives of our patients. Red light therapy has gained credibility not only among patients but also in the medical field, with several FDA-cleared devices now available for safe use.
How Red Light Therapy Works
Red light therapy uses specific wavelengths of red and near-infrared light to penetrate the skin and tissues. This light stimulates the mitochondria in your cells — the “powerhouse” of your body — helping to:
Increase cellular energy (ATP production)
Improve blood circulation
Reduce inflammation
Promote healing and repair
FDA Approval and Medical Backing
One of the most common questions patients ask is: “Is red light therapy FDA approved?” The answer is yes — the FDA has cleared multiple red light and LED devices for non-invasive treatment of skin conditions and hair regrowth. Clearance means these devices have been tested for safety and shown to be substantially equivalent to existing, legally marketed devices.
The medical field also recognizes red light therapy as a safe, non-toxic option when used appropriately. Dermatologists and pain specialists frequently recommend it as part of a comprehensive care plan.
Proven Benefits of Red Light Therapy
1. Skin Rejuvenation
Clinical studies show red light therapy can increase collagen production, smooth fine lines, reduce wrinkles, and improve skin texture. In fact, over 90% of participants in one dermatology study reported smoother skin, reduced redness, and lightening of dark spots after just 8 LED sessions over four weeks.
2. Hair Regrowth
The FDA has cleared red light devices such as combs, helmets, and caps for treating hair thinning. Clinical research shows consistent improvements in hair density and follicle health after repeated treatments.
3. Pain and Inflammation Reduction
Red and near-infrared light can penetrate deep into muscles and joints, reducing inflammation and chronic pain. Conditions such as arthritis, back pain, and post-exercise soreness have shown measurable improvement after red light therapy sessions.
4. Wound Healing and Scar Reduction
Several studies suggest red light therapy accelerates wound healing, reduces scarring, and supports better tissue repair — making it an excellent option for recovery support.
Safety and Best Practices
Studies show red light therapy is generally safe, with minimal side effects when used correctly. Some research has tested dosages as high as 320 J/cm² for skin of color and 480 J/cm² for other skin types without significant adverse effects.
To get the best results:
Use FDA-cleared devices or seek treatment from trusted professionals.
Be consistent with sessions; multiple treatments over weeks are typically required.
Protect sensitive areas, such as your eyes, during therapy.
Consult with a healthcare provider before beginning if you have specific medical conditions.
