What is veterinary class 4 laser therapy?
Veterinary class 4 laser therapy is a non-invasive light therapy for pets that uses specific red and near-infrared wavelength lasers to accelerate tissue repair and relieve pain by stimulating cell regeneration and increasing blood circulation. The core principle is that the laser light penetrates the pet's skin and stimulates the mitochondria within the cells to produce more ATP, which provides energy for cellular activity and accelerates metabolism and repair. At the same time, it promotes the growth of new blood vessels in the treatment area, increasing blood supply and delivering more oxygen and nutrients to damaged tissues. This method is suitable for the treatment of a wide range of pet diseases and injuries, including musculoskeletal problems, joint pain, soft tissue injuries, etc. It can effectively reduce the pain of pets and promote their faster recovery.
New Generation Veterinary Class 4 Laser Therapy Machines
Differences
-
Charging Method
V-Heal handheld veterinary radium physiotherapy device is charged by lithium battery with USB-C interface, and the battery life is 3 hours; Skyline 30W veterinary radium physiotherapy device supports both charging and switching modes, and the battery life is up to 12 hours by using SMA905 connector.
-
Power and Tissue Penetration
The V-Heal handheld veterinary laser therapy device has a peak power of 10W and a maximum tissue penetration depth of about 3-5cm, while the Skyline 30W veterinary laser therapy machine has a maximum power of 30W in continuous mode and a maximum tissue penetration depth of 15cm.
-
Scope of Application
Due to the difference in power and depth of tissue penetration, the V-Heal Handheld veterinary laser device is usually suitable for small animals such as dogs and cats; the Skyline 30W veterinary laser equipment has a wider range of applications, covering exotic pets, dogs, cats, horses and large zoo animals.
-
Expanded Functionality
The Skyline 30W veterinary laser equipments can be used in conjunction with a surgical laser fiber or with an endoscope for ablation, coagulation, incision and hemostasis of polyps and ulcers in the body.
-
Wavelength Configuration
The Skyline 30W veterinary laser equipment is available in 4 wavelengths: 650nm, 810nm, 915nm, 980nm, and the V-Heal handheld veterinary laser device is available in 3 wavelengths: 650nm, 810nm, 980nm. More wavelengths means more efficient absorption into target cells and better healing. In conclusion, if you mainly manage small pets at home for rehabilitation, V-Heal is a good choice; if you need more professional and faster treatment results for different types of animals, Skyline veterinary laser machines will be more suitable for your needs.
What are the benefits of veterinary class 4 laser therapy?
Accelerated Tissue Repair and Regeneration
Class 4 laser therapy stimulates cellular activity in your pet's body, accelerating the repair and regeneration of damaged tissue. The specific wavelength of the laser penetrates deep into your pet's body and reaches the damaged tissues, stimulating the mitochondria within the cells to produce more ATP, which provides energy for cellular activity, thus accelerating cellular metabolism and repair, and promoting healing of soft tissues and bones. It also promotes the formation of new blood vessels, increases microcirculation, and delivers more oxygen and nutrients to damaged tissues.
Strong Anti-Inflammatory and Reduced Swelling
Class 4 laser therapy exerts a powerful anti-inflammatory effect by reducing the production of inflammatory mediators and enhancing the activity of anti-inflammatory compounds. It helps reduce swelling and inflammation in the treated area, and is particularly useful for treating inflammatory diseases such as arthritis and tendonitis in pets. Laser therapy also promotes lymphatic circulation and accelerates the removal of inflammatory mediators, further reducing inflammation and swelling.
Effective Pain Relief
Class 4 laser therapy relieves your pet's pain through a number of mechanisms. It blocks the transmission of pain signals to the brain and increases the production of natural pain-relieving substances such as endorphins. Pets typically feel pain relief during and immediately after treatment. In addition, the thermal effect of the laser relieves muscle tension and spasms, further reducing pain.
Improved Circulation and Metabolism
Class 4 laser therapy enhances vascular activity and blood flow in the treatment area. It stimulates the formation of new blood vessels and increases microcirculation, delivering more oxygen and nutrients to the damaged tissues, thus accelerating the healing process. At the same time, Class 4 laser therapy increases the production of specific enzymes that support metabolic activity within the cell, giving the cell more energy for repair and regeneration.
Enhanced Nerve Function and Repair
Class 4 laser therapy accelerates nerve cell regeneration and improves nerve function. It helps restore damaged nerves and reduce symptoms caused by nerve damage or neuropathy. In addition, the therapy promotes the restoration of nerve conduction velocity and improves the overall functioning of the nervous system.

What are the advantages of class 4 laser therapy over class 3 laser therapy in terms of treatment?
-
Power and Penetration
Class 4 laser therapy uses a higher power laser device with a power output of more than 500mW, whereas Class 3 laser therapy has a power range of 5-500mW. This higher power allows the Class 4 laser to penetrate deeper into your pet's body to achieve deeper therapeutic results. For example, Class 4 lasers can effectively stimulate cell regeneration in deep muscle and bone, whereas Class 3 lasers work primarily on the surface of the skin or shallower tissue layers.
01 -
Treatment Effectiveness
Class 4 laser therapy produces results more quickly. For example, with vaymed's 30-watt skyline veterinary Class 4 laser device, enough energy can be delivered to the treatment area in less than 5 minutes, whereas the Class 3 laser requires more than 16 hours to achieve the same energy delivery. This means that pets can feel pain relief and functional recovery faster when treated with the Class 4 laser.
02 -
Scope of Application
Class 4 laser therapy is indicated for the treatment of a wide range of pet ailments and injuries, including musculoskeletal problems, joint pain, soft tissue injuries and more. Its powerful penetration and energy output allow it to effectively treat different depths and types of tissue damage. Class 3 laser therapy, on the other hand, may not be as effective in treating some deep tissue injuries or serious diseases due to its lower power and limited depth of penetration.

Laser Therapy Treatments & Applications

Contraindications
- Do not aim the laser beam at the eyes
- Do not use the laser on tumor sites
- Do not use the laser on bleeding tissue
- Do not use the laser to directly irradiate a pregnant uterus
- Do not use the laser on patients who are not suitable for phototherapy
Precautions
- The laser therapy machine should be used to meet the needs of the indication, and consent, guidance, or relevant safety training from a clinician must be obtained prior to use.
- Before and during the use of the laser product, the user and pets should always wear the laser protective goggles specified for this product, and other persons present should also wear the laser protective goggles specified for the product.
- When the laser device is turned on, please aim the laser at the target area and keep it moving within the surrounding 2-5cm area, if you fix the laser in one position for a long time without moving it, there may be a risk of thermal damage.
- Do not direct the laser to others or to the area indicated in the contraindications at any time.
- When the device is not in use or suspended, store the device away from children and uninvolved persons to prevent unintended use of the device.
