Frequently Asked Questions

What is red light therapy for horses?

Red light therapy, also known as photobiomodulation, is a non-invasive wellness approach that uses specific red and near-infrared wavelengths to support circulation, cellular activity, tissue recovery, and joint comfort. It is commonly used alongside veterinary and farrier care -- not as a replacement for it.

How does photobiomodulation work?

Specific wavelengths of light are absorbed by cellular components -- primarily within the mitochondria. This interaction is associated with changes in cellular energy availability and local circulation. When used consistently and appropriately, this may assist soft tissue response and overall recovery as part of a broader care plan.

What wavelengths does ReGen Equine use and why?

Is LED light therapy the same as laser therapy?

No. Both LED photobiomodulation and Class 3/4 laser therapy use light energy, but they differ in delivery method and intensity. LEDs provide broader, non-coherent light across larger surface areas, while lasers deliver concentrated, coherent light to precise points. LED systems are commonly used for ongoing wellness support and maintenance.

Is red light therapy safe for horses?

Yes. Red light therapy is widely regarded as safe and non-invasive when used as directed. It should be used responsibly and alongside veterinary guidance when addressing injuries or medical conditions. Always avoid direct exposure to the eyes.

Why does ReGen Equine use multiple wavelengths instead of a single infrared light?

Different wavelengths interact with tissue at different depths. Red light (around 660nm) primarily supports superficial tissue layers and circulation, while near-infrared wavelengths such as 850nm and 940nm penetrate deeper into muscle and dense anatomical structures. Using a multi-wavelength system -- our Tri-Wave(tm) approach -- allows for layered tissue support rather than focusing on a single depth.

Does 940nm make a real difference?

940nm is absorbed differently than 850nm and interacts with deeper, denser tissue regions. While 850nm is widely used in photobiomodulation devices, 940nm adds an additional near-infrared layer that may support deeper anatomical structures. Most consumer devices stop at 850nm. ReGen Equine includes 940nm as part of our Tri-Wave Light System(tm) to support a broader depth range.

Why doesn't ReGen Equine use blue light (around 460nm)?

Blue light wavelengths are most commonly associated with surface-level applications such as dermatological or bacterial-focused use. They have limited penetration depth compared to red and near-infrared wavelengths. ReGen Equine focuses on wavelengths more commonly associated with supporting deeper muscle, tendon, ligament, and joint structures in equine applications.

Why does coat color matter?

Research has shown that coat pigmentation and hair thickness can influence light penetration in horses. Darker coats absorb more surface light, which is one reason why device design, output, and placement all matter in equine applications. Device parameters and placement guidance are discussed at consultation.

Can red light therapy be used on acute injuries?

Red light therapy may be used during recovery phases. During the immediate acute inflammatory stage, shorter sessions or red-light-dominant use may be preferred. Always follow veterinary guidance for acute trauma or severe inflammation before beginning any supportive modality.

Are there situations where it should not be used?

Do not use directly over known tumors, areas of active infection, or uncontrolled swelling without veterinary guidance. Avoid direct eye exposure. As with any supportive modality, responsible use alongside professional oversight produces the most consistent outcomes.

Can it replace veterinary care?

No. ReGen Equine products are supportive wellness tools. They should always be used alongside -- not instead of -- qualified veterinary diagnosis and treatment. We actively encourage communication with your vet throughout any management program.

How long should sessions be?

Typical sessions range from 5 to 15 minutes per area. Begin conservatively and adjust based on your horse's response. Do not exceed 15 minutes per area unless directed by a veterinary professional. Consistency over time is generally more important than long individual sessions.

How often can therapy be used?

When will I see results?

Some horses appear more relaxed or move more freely after a few sessions. Chronic or structural concerns typically require consistent use over several weeks. Individual response varies based on the horse, the area being supported, consistency of use, and the overall care plan in place.
