Red Light Therapy

Light as medicine — backed by decades of clinical research.

Red Light Therapy (RLT), also known as photobiomodulation (PBM), uses specific wavelengths of red (630–700nm) and near-infrared (800–1100nm) light to penetrate deep into biological tissue and trigger measurable changes at the cellular level. Unlike UV light, which damages DNA, red and near-infrared wavelengths are absorbed by mitochondrial chromophores — stimulating the electron transport chain, increasing ATP production, and initiating a cascade of regenerative cellular responses.

The clinical evidence base for photobiomodulation is substantial and growing. Over 6,000 peer-reviewed studies support its efficacy for wound healing, pain reduction, inflammation, tissue repair, and neurological function. It is FDA approved, non-invasive, and produces no thermal damage — making it one of the safest and most versatile regenerative modalities available.

At HydraSpa, red light therapy is offered as a standalone session and as an integrated component of our R3 Pain Recovery and Post-Op Recovery programs. It pairs exceptionally well with IV nutritional therapy — the IV delivers the cellular building blocks while red light activates the mitochondria to use them more efficiently.

The cellular science of photobiomodulation

Mitochondrial Activation

Red and near-infrared photons are absorbed by cytochrome c oxidase in the mitochondrial electron transport chain — stimulating ATP synthesis and increasing cellular energy output by up to 150%.

Reduced Oxidative Stress

Photobiomodulation modulates reactive oxygen species (ROS) production, reducing oxidative stress in damaged or inflamed tissue and creating a more favorable environment for healing.

Growth Factor Upregulation

RLT upregulates key growth factors including VEGF (vascular endothelial growth factor) and TGF-β (transforming growth factor beta) — accelerating angiogenesis, collagen synthesis, and tissue remodeling.

Anti-Inflammatory Signaling

Near-infrared wavelengths modulate NF-κB signaling and reduce pro-inflammatory cytokines — producing a measurable reduction in local and systemic inflammation.

Neurological Support

Near-infrared light penetrates the skull and has demonstrated neuroprotective effects in research settings — supporting cognitive function, mood regulation, and nervous system recovery.

Common questions

Is red light therapy the same as infrared sauna?

No. Infrared saunas use far-infrared wavelengths (3,000–100,000nm) primarily to generate heat and induce sweating. Red light therapy uses red (630–700nm) and near-infrared (800–1100nm) wavelengths that are absorbed by mitochondrial chromophores to trigger specific cellular responses — not heat. The mechanisms and clinical applications are distinct, though both have wellness benefits.

Will I feel anything during the session?

Most clients feel a gentle warmth from the near-infrared wavelengths, but no discomfort. The treatment is entirely non-invasive — you simply relax while the light panels are positioned over the treatment area. Sessions typically last 10–20 minutes depending on the area being treated.

How quickly will I see results?

For acute inflammation and post-procedure swelling, many clients notice improvement within 24–48 hours of their first session. For chronic conditions, meaningful improvement is typically reported within 2–4 weeks of consistent treatment. Skin rejuvenation results generally become visible after 4–6 weeks.

Is red light therapy safe for all skin types?

Yes. Red and near-infrared wavelengths do not contain UV radiation and do not cause photodamage. They are safe for all skin types and tones. Eye protection is provided during sessions as a precaution against direct light exposure to the eyes.

Can I combine red light therapy with IV therapy on the same visit?

Yes — and this is one of our most effective combinations. IV nutritional therapy delivers the cellular building blocks (antioxidants, amino acids, vitamins) while red light therapy activates the mitochondria to use them more efficiently. The synergy between the two modalities amplifies the benefits of both. Our team can help you sequence the treatments for maximum effect.

Are there any contraindications?

Red light therapy is contraindicated for individuals taking photosensitizing medications, those with active cancer in the treatment area (without oncologist clearance), and during pregnancy (as a precaution). It should not be applied directly over the eyes without protective eyewear. Our clinical team will review your health history before your first session.
