Laser therapy devices stimulate atoms to emit and amplify light at a certain wavelength. This light is used to manipulate certain reactions in your body. It can be used to relieve pain or even repair damaged tissue. You need to invest in a good laser therapy machine that will help you target body tissues and deliver the results you want.

However, seeing as there are different brands in the market it is important to understand what you need to consider.  The competition in prices makes it impossible to solely depend on price as a determinant. This is why you should look into other aspects of laser therapy equipment for consideration. Here are some of the things you should consider.

Wavelength is measured in nanometers (nm). The wavelength of a laser device determines the depth of penetration. The higher the wavelength the deeper the penetration.  The common wavelengths used in laser therapy range from 620 nm to 1000 nm. 


This is a shorter wavelength that penetrates a distance of up to 1 centimeter. This laser device is perfect for treating wounds, stimulating acupuncture points, and lymphatic tissues. When you use a laser therapy device with this wavelength, you can expect an increase in blood circulation and improved metabolism. This is mainly because the blood can easily absorb the energy from the laser light.


This wavelength comes with a penetration distance of up to 5 centimeters. It comes in handy when treating tendons, ligaments, and tissues. It interacts with the mitochondria to speed up the metabolism of tissues and repair damaged cells. 

900nm -1000nm

This is a class 4 laser that provides a lot of energy when used on your body. The energy is converted to heat which is absorbed by your body tissues. This helps repair any damages and aids in the healing of any wounds. 

Class Level


There are 5 different class levels including class 1,2,3A,3B, and 4. These low-level laser therapy devices vary because of their power and efficiency. Laser therapy devices between classes 1-3A use very low power and may have no significant effect on your treatment. Class 3B laser devices have a power of 500 mW and can be used for homes as directed by a medical professional. 

Class 4 devices have a power output of more than 500mW and can damage the eyes and tissue if not properly used. However, this high power allows for enough energy to be passed to the nerves, muscles, and ligaments within a short time.

Pulsing Option


Different laser devices come with different pulse frequencies. These frequencies differ because they have different effects on the body. Low pulse frequencies are best suited for minor injuries while sub-acute injuries benefit from high pulse frequencies. For chronic pain, the only frequency that is sufficient enough is the continuous mode. Seeing the different pulsing options, you should consider what you intend to do with your device.



Laser therapy protocols are the things you need to observe when using these devices. It is almost like a manual that will guide you through. Most laser therapy devices include these protocols with their product packages. This is why you need to do your research to find out which laser machine manufacturers offer this as an option. 



Your laser therapy device has a power output that determines the efficiency of the treatment. When the power is high, then the time taken for treatment is greatly reduced. However, if the power is low then it will take much longer to deliver the same results. Consider this when getting a laser therapy device. This will help you decide whether the amount of time spent in treatment affects the choice you’ll make.



This is by far the most thought about factor when choosing a laser therapy device. You’ll want to consider the devices that fall under your budget and how flexible you are in adjusting it. If the device that meets all your expectations is a bit too pricey, consider checking with other suppliers. Remember, there are numerous brands in the market with competitive pricing. You are bound to find one that will check all the boxes. 


Choosing a laser therapy device requires you to be well informed about what laser therapy is and what is needed in a quality device. Take your time to go through all the factors that will influence your buying decision to make sure you make a wise one. Consult different manufacturers and remember to read the ratings and reviews sent by other users. This will help you see if what the device promises is what it delivers.

Laser therapy can be used to treat muscle soreness, back pain, joint diseases, and sprains. If you are suffering from any of these, there are lots of treatment options for you to consider. However, laser therapy is more advanced and less intrusive which makes it the perfect option. Here are a few reasons why laser therapy will help relieve your pain:

Table of Contents

Helps Repair Nerve and Tissue Damage


A laser therapy machine uses photons of light to get to the nerves and tissue of your body. This helps accelerate growth and reproduction which will result in the repair of any tears. When this happens, your tissues grow back stronger and have an increase in energy.  It also facilitates rapid waste product removal from your body that could add to the pain if left unattended to. 

Increases Blood Flow


Laser therapy devices facilitate the fast repair and healing of blood capillaries and arteries around your damaged tissue. This will help increase blood flow through your body. Blood carries important nutrients that help your tissue heal. The increased blood flow also means that waste products will be flushed out of your system faster. This will help reduce the pain you might be experiencing. 

Reduces Swelling


With blood flow increased, the molecules that contribute to swelling and inflammation are carried away together with other waste products. A decrease in these molecules will reduce swelling significantly and relieve your pain. 

Stimulates Production of ATP


ATP refers to stored energy that is used by your body to accelerate the healing process and relieve pain. Laser therapy activates certain enzymes that work to increase the production of ATP.  When you have an injury, the levels of ATP are very low which makes the healing process take longer compared to when you use laser therapy.

Improves Vascular Activity

Laser therapy helps your capillaries and veins work with improved efficiency to facilitate the continuous flow of blood. With this kind of efficiency, your heart’s activity is improved significantly. Your wounds heal faster thanks to the blood flowing in and out of the heart. Remember, blood carries both oxygen and waste products. So when it gets to the heart the blood is cleaned and your wound is supplied with enough blood to facilitate your recovery.

Accelerates Wound Healing


A laser treatment device stimulates the production of collagen to your body. Collagen is the main protein that helps your wounds and burns heal with ease. The production of collagen also stimulates fibroblasts that help repair old tissue and repair any damaged tissues.

Stimulates Acupuncture Points

Acupuncture normally consists of painful needles pricking your body at different places. However, with laser therapy, you can easily access these acupuncture points. It will help you enjoy the benefits of acupuncture without having to go through all the needling pain. 

Activation of Stem Cells


Stem cell therapy is a great way to accelerate healing and reduce pain in the process. Laser therapy is one of the ways you can achieve this. These stem cells can be activated from different parts of your body including the bone marrow. When these stem cells are activated, they work to regenerate damaged tissue which will result in faster healing.

Reduces Muscle Soreness and Fatigue


This is perfect for home laser therapy where you can easily use your machine after an intense workout. If you’re feeling any soreness after a workout, laser therapy will go a long way to easing the discomfort. It works by decreasing nerve sensitivity and releasing endorphins that naturally relieve pain. Consider getting a laser machine for your personal use to help reduce your downtime after an injury in the gym.

Improves Joint Mobility

Targeted laser physical therapy can not only help reduce joint pain but also improve mobility and range of motion. It works by reducing swelling and numbing pain to a point where it is bearable to accommodate motion. Over time, the pain and swelling subside and leave tissue strong and repaired. This will significantly increase your mobility.

Improves Muscle Strength

For muscle tissue to be repaired fully, you’ll need sufficient blood flow with nutrients and oxygen. With this, your muscles get stronger and can withstand the pressure that comes with working out. After a workout, consider having a laser massage therapy to keep the muscles strong and keep soreness at bay. 


Laser therapy is an amazing option if you want to relieve pain. You can do it yourself or get a consultation with a specialist to get adequate help. If you decide to do it yourself, research the best laser therapy machine suppliers and get a quote on their products. You should also make sure that you lean how to choose the right device and how it works for best results.

What is Cold Laser Therapy?

Cold laser therapy is the treatment of pain and stimulation of healing in the body using very low-intensity light. It is referred to as cold laser therapy because, although it uses light, its frequencies vary significantly from other laser therapy options. The light produced by this laser therapy machine has a low frequency which means it cannot heat your body tissues. This type of laser therapy is also known as; 

How Does Cold Therapy Work?

A- man-using-a-cold-laser-therapy-device-on-his-shoulder

When using cold laser therapy, your doctor will apply the laser therapy device to the specific targeted area. Cold laser therapy uses different wavelengths of low-level light that are then absorbed by the body tissues. When the cells are hit with this light, they trigger a chemical reaction that helps them regenerate and repair. 

The duration of this procedure depends on the device being used. This means that you have to make sure the device being used is up to standard. Focus on the wavelength and penetration of your device. Typically, superficial tissue is treated using 600nm – 700nm while deeper penetration only requires 780nm – 950nm.

What is Cold Therapy Used For?

Now that you know what cold laser therapy is and how it works, the big question remains. What is it used for? Well here are a few ways cold therapy can help. 

Reducing Inflammation

Inflammation on the hands

Laser therapy stimulates blood circulation throughout your body. This means that the area you want to treat will get enough blood flow. Blood flow is important because it carries nutrients and oxygen that help your wounds heal faster and easily repair tissues.

Blood also gets rid of waste products in the affected area. This means that the molecules that contribute to inflammation will also be carried away. This will go a long way in reducing the inflammation you’re experiencing.

Relieving Pain

Your body releases a pain eliciting chemical called bradykinin that enhances nerve sensitivity when injured. Laser therapy works to decrease this chemical and normalize ion channels. It also stimulates the production of endorphins ( natural pain reliever) that provide you with an analgesic effect. 

Skin Rejuvenation


If you’re suffering from acne, hyperpigmentation, burns, and other skin issues you should try using laser therapy as treatment. It has become well known in the skin rejuvenation industry being used by many dermatologists to work wonders. The good thing with this is that you can get a home laser therapy device and learn how to use it. 

Improving Lymphatic Systems


Your lymphatic system is responsible for returning important nutrients and water from different tissues back to the bloodstream. In essence, it is a drainage system that is very useful to your body. When any part of your body is congested, then drainage becomes impossible. This is where laser therapy comes in. It works to relieve the congestion and stimulate more lymphatic drainage. This will also result in faster healing.

Facilitating Weight loss


Cold laser therapy can be used to aid in weight loss mainly because the light that penetrates your body stimulates the fat burning process. Granted, working out and a general lifestyle change would be easier. However, you can consider laser therapy treatment to help accelerate the process.



For those people who are terrified of needles, using laser therapy equipment is the best option. If you are worried about missing out on all the amazing benefits of acupuncture, worry no more. Laser therapy works to stimulate all acupuncture points without the pricking pain involved when using needles. 

Wound Healing


Collagen is a protein that is used to heal wounds and burns. A low-level laser therapy machine is used to stimulate the production of this protein to ensure faster healing and recovery. 


Cold laser therapy cuts across different body issues and can help you address them with ease. Take your time to learn more about it and consult your doctor for advice. Your doctor will be able to pint you in the right direction and refer you to actual professionals who’ll deliver what you want. 


More and more people are embracing laser therapy as a form of treatment for various health issues. A laser therapy machine is quite fascinating. It can remove the moles on your skin while on the other hand, it can be used to completely get rid of a tumor. Impressive right? Here are a few things you should know about laser therapy.

What is Laser Therapy?


Laser therapy is the use of focused light to treat different body ailments. It can be used to relieve pain, remove tumors, and even treat acne. Laser therapy is quickly gaining momentum because of the precision assured as compared to normal surgery. Your doctor is able to treat you without affecting any surrounding tissues or cells. Laser treatment therapy also assures less pain and swelling after the procedures. It might be a bit expensive and you may need a few sessions considering the level of damage control needed.

How Does Laser Therapy Work?


Laser therapy devices use focused light that is tuned to a specific wavelength and frequency. The tuning helps make sure that the laser will do the task at hand without causing any other damages. This is because the beams from the laser light can be very intense. This kind of intensity is used when cutting steel and shaping diamonds. You wouldn’t want such intensity anywhere near your body, right?

Every procedure done on your body using laser therapy equipment requires the use of a certain frequency and power. This is mainly to control the level of penetration through the skin. In most cases, superficial wounds only need low-frequency light with low penetration while deeper tissues require the use of high-frequency light for deep penetration.

What is Laser Therapy Used For?

Now that you know what laser therapy is and how it works, it is important to learn more about what it is used for. Here are a few ways laser therapy can help;

Improving Vision


As the years go by, most people start experiencing some vision impairment especially when it comes to reading. There has been no treatment to alleviate this condition. People always turn to use reading glasses to help make it easier for them to read. However, you can use laser therapy to help address this issue. Laser eye surgery will help improve your vision and restore both distance vision and reading vision.  

Treating Hair loss

Hair loss is a daily occurrence that requires no cause for alarm. However, if you’re experiencing hair loss without significant hair growth, this should be worrying. This is because it means that you’re simply losing hair and could go bald if the problem is not addressed. There are different treatment methods for hair loss including laser therapy. 

Laser therapy releases photons into the scalp tissue that is absorbed by weak cells. The absorption of the photons works to encourage the growth of hair. This procedure is safe, tolerable, and less invasive compared to other hair loss treatments. 

Relieving Pain


One of the chemicals that is released when injured is bradykinin. This is a pain eliciting chemical that enhances nerve sensitivity and makes the pain unbearable. To get rid of the pain completely you need to find a way to get rid of this chemical. Laser therapy is one of the best ways to relieve this pain. The light produced during laser therapy normalizes ion channels and decreases this chemical in the process. In addition to that, it also stimulates the production of endorphins (natural pain reliever) that work to reduce nerve sensitivity and provide an analgesic effect.

Reducing Swelling


When you get injured, the natural response of your body is to rush nutrients, water, and oxygen to the affected area. This is meant to facilitate faster healing and recovery. However, if your lymph glands are not working at their best, then drainage will not be as required. This will lead to an accumulation of waste and nutrients in one place which will result in swelling. Laser therapy is used to increase blood circulation and improve your lymphatic system. When your lymphatic system is at its best, drainage of waste products will be easier and faster relieving the area from the swelling.

Removing Warts, Moles, and Acne

Laser therapy has become a great skin rejuvenation method in most dermatology centers. It works by addressing the surface of the skin and removing any unwanted marks. The moles found on your body require attention especially because they can turn cancerous. This is why most people turn to laser therapy to remove them. 


Laser therapy is used to treat different issues and is a non-invasive procedure. It is the perfect treatment option for anyone who wants to avoid the use of needles and scalpels. It also cuts the treatment time significantly and helps you heal faster compared to other treatment procedures. Take your time to evaluate your treatment center and the devices that will be used. Familiarizing yourself with this will give you peace of mind when undergoing the procedure.

The photons present in the Laser emission enter the intended tissue and are immediately absorbed by the mitochondria. These photons are then converted into chemical energy in the form of what is known as ATP. This triggers the cell membrane to become permeable, which in turn triggers a physiological change. Some of the changes affect body cells and nerve conduction rates. Just to be clear, the process is photochemical, not thermal.

Benefits of Laser Therapy

Laser therapy has some benefits that other conventional means of treatment do not have. The following are some of the notable ones.

It is Precise and Painless

The laser light used in medical laser therapy is very precise and targets the intended area with astounding accuracy. Because of this, there is less damage to the healthy surrounding areas since they will barely be touched by the light. This makes the method painless when you compare it with the normal forms of treatment.

It is Non-Invasive

When undergoing laser therapy surgery, you will barely feel it. The common misconception about this form of treatment is that people expect to feel a lot of heat since there is light involved. Laser therapy is not thermal; it is a photochemical process; therefore, it is non-invasive; you will not even know when the process has begun or when it ends.

It has no Known Side Effects

Conventional treatment methods, like surgery, have very heavy side effects. If you are from the surgical table, for instance, you may not be able to talk and walk for a while due to the lingering effects of anesthesia. Side effects of laser therapy are a thing of the past. There is no administration of drugs or the need for pain-numbing drugs.

It Stimulates Rapid Healing

Laser therapy stimulates the lymph and increases vascular activity, making blood circulate more efficiently. This, in turn, stimulates the cell reconnection process, which brings back damaged and numb areas of the body back to life. It also stimulates the development of fibroblast in damaged tissues, which in turn reduces the recovery times, accelerating the healing process, something that usually takes a while when other forms of treatment are involved. 

It Does Not Leave Scars

Unlike invasive treatment methods that leave permanent scars on the skin, laser therapy is non-invasive and leaves the skin as perfect as it was. It pulls this off by minimizing the fibrous tissue, which is usually responsible for the formation of scars on the incised areas after surgery. It could be argued that laser physiotherapy is a better alternative for most minor surgical processes.

Highly Effective for Complicated Conditions

Laser therapy is the best go-to option for some of the most complicated health issues. Sometimes the conventional drugs don’t just cut it, and at times, a safe way to deal with a known issue may not be available. It is during moments like this that laser therapy comes through. Some conditions like arthritis, carpal tunnel syndrome, fibromyalgia pain, among others, can be better handled by cold laser therapy.

Involves Little to No Administration of Drugs

Low level laser light therapy is a variation of the broader laser light therapy that is sometimes called photomedicine. It is a non-invasive method of treatment that is drug-free. It simply deals with the affected areas of the body it is focused on, and treatment takes place on the spot: no injections, no long list of prescriptions, and no need for pain-numbing medication.

They do Not Interfere with Implants

Laser therapy can be used safely on people who have vital implants like pacemakers without affecting how they operate or interfering with their rhythm. Laser therapy does not emit any electromagnetic pulses; it only emits photons which cannot be absorbed by metals. Therefore people who have various types of implants can undergo laser therapy.


Laser therapy is quickly becoming the preferred mode of treatment, and as laser therapy equipment improves with time, the possibilities are unlimited. There is great hope that in the future, laser therapy will provide the much sought after breakthrough in the treatment of serious diseases like cancer that have plagued humanity for years. Rapid tissue regeneration is also another area that is holding much promise.
