Red Light Therapy for Scars

In the United States, there is an annual $12 billion market for scar treatment.

Do you have a scar that you would like to fade or have completely gone? If so, red light therapy for scars is a great solution.

Read on to learn more about the benefits of red light therapy for scars and how you can use a red light therapy device at home to see great results.

What Is Red Light Therapy?

If you’ve never heard of this type of therapy before, you might be wondering “How does red light therapy work?” or “What does red light therapy do?”

Red light therapy is a treatment that uses a special RLT device with red light wavelengths (the longest wavelengths on the visible light spectrum) to stimulate the production of adenosine triphosphate (or ATP). ATP is the preferred fuel source for the cells of the body.

This type of therapy is also known as RLT, photobiomodulation, red light laser therapy, and red and infrared light therapy.

The best red light therapy to treat scars is the 300W RLT device as it's designed for targeted areas on the body.

Red Light Therapy Pros and Cons

If you’ve never seen a full-body red light therapy before and after the picture or a face red light therapy before and after the picture, you might be wondering whether or not red light therapy truly works or if it’s worth the time and money required.

As is the case with any type of skin treatment, there are pros and cons to RLT products. Here are some of the most important ones to consider:


  • Easy to use
  • Passive skin treatment
  • Little-to-no discomfort besides some warming and mild tightness
  • Treats skin on a cellular level for real and noticeable results


  • Not ideal for sensitive skin
  • Requires consistent use for the best results
  • Treatments can be expensive, especially if you go to a medspa or dermatologist’s office each time

Red Light Therapy Benefits for Scars

The body forms scars as part of its natural healing process. After the skin has been cut or damaged in some way, it grows new tissue to repair itself. The new tissue pulls the wound together and fills in gaps left behind by the injury.

Scar tissue is primarily made up of collagen, which is one of the most abundant proteins in the body. Scars can develop in a variety of shapes and sizes, too; some are flat, some are raised, some are sunken, etc.

When it comes to treating scars of any kind, there are lots of reasons to consider using a red light therapy lamp. The following are some of the most important benefits to keep in mind:

Reduced Inflammation

Red light therapy is best known for reducing inflammation and combating the effects of oxidative stress on the cells.

Regular exposure to an RLT device helps to support the body’s natural tissue repair and regeneration processes. It does this by penetrating the tissue 8 to 10 millimeters deep.

Faster Healing

In addition to reducing inflammation, red light therapy also helps to speed up the wound healing process.

Red light therapy helps to stimulate blood flow and delivers oxygen and nutrients to damaged tissues. This, in turn, brings down inflammation and helps the body to recover faster from the inside out.

Increased Collagen Production

Red light therapy also helps to increase the production of collagen. Collagen is one of the most abundant proteins in the human body, and it’s essential to the integrity of the skin and joint tissues.

Scars are indeed the result of excessive collagen buildup. However, stimulating collagen production with red light exposure causes the collagen to form a flat, lattice-like surface, rather than piling up. 

This replaces unattractive, raised scar cells with healthy tissue. As a result, a scar’s appearance can be minimized dramatically.

Increased Stem Cell Activation

Another reason why red light therapy reviews are generally positive is the fact that RLT devices activate stem cells. Stem cells are unspecialized cells that can develop into any type of specialized cell the body needs.

When a person has a skin wound, for example, stem cells become specialized, healthy skin cells. This encourages the growth of normal skin cells, rather than those that make up scar

Can You Use Red Light Therapy at Home?

Some of the best red light therapy results come from those who use a red light therapy light at home. 

Driving to and from a medspa or dermatologist’s office multiple times per week isn’t practical (or affordable) for most people. However, sitting in front of an in-home red light therapy device is.

It doesn’t matter if you use a tabletop red light therapy tool or a set of red light therapy sauna panels. You can have great red light therapy before-after results if you use your device properly. Here are some tips to help you do this:

  • Consult a Dermatologist: Check with a dermatologist before getting started to ensure your skin is well-suited for red light therapy; it’s not ideal for some people with very sensitive skin.
  • Be Consistent: Consistency is key when using red light therapy treatments; it takes time to see results, and you need to use your device regularly.
  • Schedule Your Sessions: If you struggle to be consistent, write your red light therapy sessions into your schedule so that you don’t forget about them.
  • Start with Short Sessions: Begin with short sessions — just 5 minutes is a good starting point — you can increase gradually over time once you ensure you don’t have any negative side effects.
  • Take Care of Your Skin between Sessions: Care for your skin between treatments by applying moisturizer and wearing sunscreen whenever you’re outdoors.
