Red Light Therapy for Healing Scars

Scars are marks left on the skin after wounds, surgical procedures, or injuries have healed. They can remain permanent for years if left unmanaged. Scars can easily catch anybody’s attention because they look different from your skin tone, and most of them stand out in a negative way. 

Most of these scars fade over time, but they never really disappear. Red light therapy has been known to heal scars, as shown by several studies. 

Red light therapy devices work by emitting wavelengths of light, enabling it to stimulate the production of adenosine triphosphate or ATP, cellular regeneration, and remove oxidative stress. Your body’s healing process now becomes faster because of red light therapy. 

A study in 2019 revealed that red light therapy is a promising strategy to minimize scar formation after surgery by stimulating normal skin growth and regular collagen organization. The same study mentioned that red light therapy must be initiated within one-week post-surgery to coincide with the first stage of wound healing. This study’s success may significantly impact the current treatment paradigm for fibrotic skin diseases [1].

Besides promoting repair and regeneration, red light therapy also activates stem cells to become normal healthy cells that will restore the production of new skin cells with different genetic makeup. This claim is backed by a study that revealed a wide range of red light therapy applications for dermatologic purposes [2]. 

The same study also revealed how red light therapy works in treating hypertrophic scars. What are hypertrophic scars? Hypertrophic scars are a result of an abnormal response to injuries. These scars are wide, thickened, and often raised. They develop from the area where an injury happens.

What LED Light is Best for Scars? 

Since the 1960s, LED or light-emitting diodes have shown promising results in human tissue growth. Nowadays, people have discovered the health benefits they can bring to our skin [3]. Yet, the best LED light for treating scars is red light. 

Red light works best for treating scars by acting on fibroblasts to promote healthy production of collagen, a type of protein that’s responsible for the healing and regeneration of tissues. To increase collagen production with different genetic makeup from your scars, red light therapy will be needed [2].

How Long Do Scars Stay Red After Surgery? 

Scars are a normal part of the healing process. Most of them become permanent once your body cannot produce a new organization of collagen. 

The redness of your scars after any surgical procedure doesn’t subside immediately. There’s also no known method to get rid of the redness in an instant. Fortunately, red light therapy can help. 

According to a study in 2008, scar redness fades at an average of seven months. However, it’s also stated in the study that redness is influenced by the wound type and position [4].

Effect of Red Light Therapy on Wound Healing 

Wound healing involves distinct phases, from clotting to new tissue growth. Your body doesn’t automatically heal on its own, which is why you’re here to look for a regimen that might hasten the healing process. Red light therapy has a reliable clinical record for healing wounds, whether it’s a regular cut, an incision, or an excision. 

Red Light Therapy for Open Wounds

A study in 2018 indicated that red light therapy could increase tensile strength and wound contraction for faster healing. Animal subjects in the study experienced less pain and became more responsive to red light therapy after surgery. It also concluded that red light therapy for open wounds and treating suture is effective [5].

Another study also revealed that red light therapy improved the healing progression in patients who underwent coronary artery bypass grafting (CABG) treatment. In the same study, red light therapy provided an analgesic effect on the patients and increased their incision healing while preventing dehiscence [6].

Infrared Light for Healing Wounds

Infrared light also works well for healing wounds. One study involving postnatal women showed a result stating that episiotomy wound healing was rapid with an infrared lamp therapy. 

The heat of the infrared light penetrates three inches deep into the body and causes an increase in blood circulation, a reduction in redness and edema, prevention of microorganism growth, and faster wound healing [7].

Recovering from Plastic Surgery with Red Light

The analgesic effect of red light therapy can be applied in all postoperative environments. Plastic surgeries are not an exemption. Since these procedures involve a different kind of inflammation and pain level, red light therapy after surgery will be much appreciated. This regimen provides natural healing from surgery. Red light therapy heals surgery wounds faster. 

Red light therapy allows patients who undergo plastic surgeries to heal sooner than expected. Also, it helps in reducing bruising and swelling. A study in 2015 concluded that red light therapy contributed significantly to the healing of acute wounds and the improvement of burn scars in 28 animal trials and 12 human trials [8]. 

Red Light Therapy to Speed Up Skin Regeneration

Laser therapy for healing involves processes that include skin regeneration.

Red light therapy for injuries works best because it speeds up skin regeneration by promoting boosting collagen production, lowering inflammation, and restoring growth of new skin cells [9].

Reducing Scarring From Burns 

Red light therapy also reduces scarring from burns by speeding up collagen production and promoting faster skin regeneration or faster growth of new cells needed to replace the affected ones. One study in Brazil revealed the red light therapy’s effects of mammals with third-degree burns. The results showed an increased production of collagen and a decrease in the number of inflammatory cells. This indicated that red light therapy led to faster healing compared to other treatment methods [10].

Thus, red laser light for healing and speeding up skin regeneration gives you the best results.

Red Light Therapy Decreases Post-Surgery Pain and Inflammation 

Red light therapy also decreases post-surgery pain and inflammation by regulating the metabolic and cellular processes needed for the body to respond to post-traumatic situations.  

When red light therapy is applied after a surgical procedure, it will help to:

  • Promote faster healing of acute or chronic wounds.
  • Promote the anti-inflammatory process of the body and reduces post-surgery pain.
  • Promote healing where other alternative treatment methods have failed.

A study in 2019 concluded that red light therapy could be considered as an appropriate modality for reducing pain after surgery [11].

Healing Friction Burns with Red Light Therapy

Friction burns are a type of abrasion that causes damage to the dermis because the epidermis has been detached or lost. These burns don’t involve heat but are still considered second-degree burns.

Red light therapy has become popular in being a natural method for treating burns. Several clinical trials and studies also exist to back up such claims. All the results revealed faster healing, reduced pain, lesser inflammation, less oxidative stress, and reducing scarring from burns.

Red light therapy has been proven to help heal friction burns faster, as evidenced by a study in 2015 involving rats. It was also found that healing a second-degree burn during its proliferative phase dramatically impacts the outcome of the red light treatment. The same study showed an increase of macrophage and myofibroblast numbers within ten days using red light therapy [12].

Another study on 138 burned patients has also proven that systematic red light therapy once a day for 30 minutes effectively healed deep-thickness burn wounds [13]. 

LED Treatment for Acne Scars

Is LED light therapy for scars effective? Are LED healing lights worth it? Skin rejuvenation is another benefit you can get from LED treatment. Since acne scars affect you aesthetically and medically, you need to learn how to get rid of them in a more natural, safer, and non-invasive way. 

Red light treatment for acne scars works by stimulating the fibroblasts responsible for producing collagen while stimulating new cell growth with different genetic makeup. One study showed promising results, as evidenced by reduced inflammatory lesions. Red light works by influencing cytokine release [14].
