A lot of people struggle with various injuries, aches, or diseases. For decades treatment would be expansive and agonizing. However, in 1967 a Hungarian scientist Endre Mester discovered cold laser therapy, which became a game-changer.

What is cold laser therapy?

When you hear “Cold laser therapy” you probably think of ice, freezing, and enormous pain. However, these things have nothing in common with therapy itself. “Cold” simply states the inability to heat your skin due to the usage of low levels of light. As for those who fear lasers — relax; it is a non-invasive therapy, so you will not feel a thing. Cold laser therapy got its fame for being a painless way to heal your wounds, treat sprains and muscle spasms, resolve skin problems, help with chronic aches and even boost hair growth

It is also called:

  • Low-level laser therapy (LLLT)
  • Low-power laser therapy (LPLT)
  • Soft laser biostimulation
  • Photobiomodulation
  • Low emitted diodes (LED) therapy 

A cold laser therapy device has wavelengths from 600 to 890 nanometers, it is easy to use, portable, and just as good as the one at a doctor’s office. This device will help you not only in a physical way but financially as well. Firstly, you do not have to spend money and time on doctors, since you can always use it at home or on your way. Secondly, this device is also meant for animals, so there is no need to buy an extra one for them.

How does cold laser therapy device work?

Low-level red and near-infrared light waves apply directly to your skin helping cells to regenerate. Wavelength varies from 600 mn to 890 nm depending on the needs (650 nm – 680 nm for wounds, bruises, and 800 nm – 890 nm for joint pain, or inflammatory-related ailments). Longer waves mean deeper penetration into body tissue, which enables the device to treat more complex cases. 

Every device has different time settings, though usually, people take 5-10 minutes sessions.

Low-Level Laser Therapy (LLLT) has been shown to increase the proliferation of these types of cells:

  • Fibrolates (produce collagen and elastin)
  • Keratinocytes (produce the protein that makes up skin, hair, and nails)
  • Endothelial cells (found in blood vessels, lymph vessels, and the heart)
  • Lymphocytes (white blood cell that’s an important part of the immune system)

Therefore, skin gets softer, wrinkles disappear, hair grows better and stronger, improves blood circulation. People experience pain relief, and animals become more active.

What do cold laser therapy devices help with?

Skin problems

Skin imperfections bother lots of people. That’s where cold laser therapy will assist you. It treats:

  • Acne
  • Psoriasis
  • Burns
  • Swellings
  • Dermatitis

Sport injuries

People use the devices often after training to reduce pain or in case of injuring themselves. LLLT works for:

  • Minor injuries
  • Sprains
  • Bruises
  • Spasms
  • Strains
  • Knee, back, and neck pain

Wound healing

The device stimulates damaged tissues to repair. It is commonly used to treat internal and external wounds. Lasers quicken the body’s natural healing processes by using a wavelength of light to boost blood flow at the wound.

Types of wounds that can be healed with a light therapy device: 

  • Infected wounds
  • Pressure ulcers
  • Diabetic wounds
  • Arterial ulcers
  • Chronic wounds
  • Surgical wounds

Pain relief

Cold laser therapy reduces nerve sensitivity by decreasing bradykinin (a chemical that causes pain). It releases endorphins (chemicals produced by the body to relieve pain). LLLT has a pain-blocking effect on certain nerve fibers.

The device also helps with:

  • Migraines and headaches
  • Traumatic brain injury
  • Mouth infections
  • Chronic pain
  • Arthritis

Hair loss

Cold laser therapy encourages hair growth. In a study [1] 44 males aged 18 – 48 got their hairs trimmed to 3 mm height. The patients had a 40% increase in hair growth following the 4 months of treatment. LLLT irradiates photons into scalp tissues. These photons are absorbed by cells to improve hair growth.

Pet diseases

Low-laser therapy relieves your pet’s pain. It activates acupressure points that provide musculoskeletal relief as well as blocking nerve receptors to reduce pain.

The device is irreplaceable in situations like:

  • Wound healing
  • Spine disease
  • Postoperative stitches
  • Osteoarthritis
  • Muscle injuries
  • Skin conditions

How effective is cold laser therapy? Based on scientific research

Effectiveness for humans

Cold laser therapy is safe and approved by the U.S. Food and Drug Administration (FDA). This particular criterion means that the product was tested several times under the supervision of professionals. 

The effectiveness of the therapy was checked by various researchers. American, Australian, and British scientists have conducted research [2] trying to find out whether low-laser therapy is an effective technique for pain relief. The researchers have stated that LLLT does help relieve pain and promotes healing processes in the body. More common methods, such as steroid injections, acupuncture needles, and anti-inflammatory drugs are less safe and have side effects in comparison with cold laser therapy.

In one study [3] 300 people with wrinkles tried LED therapy and 90% of them declared their skin to be softer after a few sessions. They have also experienced a reduction in roughness and fine lines ranging from a significant reduction to sometimes subtle changes.

Twenty-eight patients participated in a study [4]. Patients with acne vulgaris and age above 18 years were treated with red LLLT (630 nm) and infrared LLLT (890 nm) on the right and left sides of the face respectively, twice per week for 12 sessions. Ten weeks after treatment acne lesions were significantly decreased in the side treated by 630 nm LLLT (length of the wave in cold laser therapy device).

Another study [5] showed positive results of herpes treatment. 50 patients with recurrent perioral herpes simplex infection applied LLT daily for 2 weeks. It was shown to decrease the frequency of herpes labialis episodes. However, you should keep in mind that a cold laser therapy device is not a magical cure for all your troubles, so do not expect diseases to go away. No, the device simply helps you to overcome pain and improves some medical conditions.

Effectiveness for animals

This therapy is also widely used on animals like dogs, cats, horses, and mice. A group of scientists has conducted research [6] aiming to find out how dogs` bodies react to it. For the study 2 female dogs and 3 male dogs, aged between 2 and 9 years old, of 3 different breeds (1 crossbreed, 1 Cane Corso, 3 English Bulldog) were chosen. In each dog, one lesion was designated as the control (treated with a Cortavance® spray) and other lesions were treated with a light therapy device, daily for 5 days and follow-ups for two months.  Results proved LLLT`s healing effect of injuries in subjects.

Veterinarians from different clinics not only support cold laser therapy devices but also advise people to buy them for home use.

📢Tip: when using on animals shave the treating area

Who can’t use a cold laser therapy device?

Even though cold laser therapy devices help people and their pets with various health problems there are still some exceptions for those who can use them. Women are recommended to avoid the device during pregnancy as its effect on fetuses is not well-researched.

It is risky for people diagnosed with cancer to use the device since it might stimulate tumor growth. Those with blood diseases (anemia, hemophilia, blood clots) and epilepsy are in the same boat.
