Will red light therapy help with scars?

Scars, whether from surgery, acne, injuries or trauma, can make you self-conscious about your appearance. Scars may also cause discomfort, tightness, itching or mobility issues. You likely want to diminish the look of scars, but traditional options come with risks and side effects. Red light therapy offers a safe, non-invasive way to significantly improve the appearance and texture of scars.

What is red light therapy

Red light therapy, also known as low-level light therapy (LLLT), is a type of phototherapy that uses red and near-infrared light to stimulate cellular function. The light is absorbed by the mitochondria in the cells, which helps to increase energy production and promote healing. It is a safe and effective treatment for a variety of conditions, including scars and it is now widely available for home use.

What color LED light can treat scars?

Red and near-infrared LED lights are the most effective colors for treating scars. These wavelengths penetrate deep into the skin, stimulating collagen production and reducing inflammation. Red light therapy can also help to reduce the appearance of scars by improving blood flow and promoting the growth of new, healthy skin cells.

How red light therapy works for scars?

Increases Collagen Formation – Light exposure stimulates fibroblasts to produce more collagen and aligns the new collagen properly to diminish scar rigidity and tightness.

  • Reduces Inflammation – The light reduces pro-inflammatory cytokines and enzymes breaking down collagen to calm irritation.
  • Increases Circulation – Better blood flow provides oxygen and nutrients that facilitate tissue regeneration and scar remodeling.
  • Promotes Wound Healing – Light exposure accelerates the proliferative healing phase to properly repair damaged skin.
  • Improves Skin Cell Energy – More available ATP energizes skin cells for optimal function and regeneration of healthy tissue.
  • Softens Scar Tissue – It properly aligns the cross-linking between collagen fibers making scars more supple.
  • Evens Skin Texture – The light promotes a more normal turnover and maturation of skin cells for smooth skin.

These diverse yet synergistic mechanisms make red light highly effective at rehabilitating injured skin and reducing scars.

The Science of Red Light Therapy for Scars

There is a growing body of scientific evidence to support the use of red light therapy for scars. A 2004 study found that red light therapy was effective in reducing the pain and itching associated with scarring. Study participants received red light therapy twice a week for eight weeks. The results showed that the participants who received the red light treatment had significantly less pain and itching compared to the control group[1]. Another 2016 study showed red light therapy as an emerging treatment modality for treating skin scarring[2]. These studies provide strong evidence that red light therapy is an effective treatment for scars.

How to Use Red Light Therapy for Scars at Home

To achieve optimal scar reduction, follow these best practices:

– Use wavelengths in the 630 to 660 nm range which are clinically proven most effective.

– Position scar tissue directly in front of and very close to the light panel.

– Treat for 10 minutes at a time to allow light penetration into deeper scar tissue layers.

– Use treatments daily or at minimum 4 to 5 days per week for compounding benefits over time.

– Increase session duration to 15 or 20 minutes for older, thicker scars.

– Apply gentle pressure massage to the area after treatments to better disperse scar fibers.

– It is important to use red light therapy consistently to see the best results.

Which is the best red light therapy company?

Red light therapy is a safe and easy-to-use treatment that can be done at home. To use red light therapy for scars, you will need a red light therapy device. There are many companies that offer red light therapy devices for home use. When choosing a company, it is important to look for one that uses high-quality LED lights and has a proven track record of effectiveness. One of the best red light therapy companies is RedDot, which offers a variety of devices for home use. RedDot LED devices are made with medical-grade LED lights and have been clinically tested for effectiveness.



In conclusion, red light therapy is a natural and effective way to improve the appearance of scars. By using red and near-infrared LED lights, you can stimulate collagen production, reduce inflammation, and promote the growth of new, healthy skin cells. While patience is required, red light can gradually fade and erase scars from the inside out through biological regeneration of healthy skin. Give your skin the chance to rediscover its natural radiance and be free from the bounds of scarring.
