Does Red Light Therapy Improve Scars?

Scars are an unavoidable skin problem in our lives. Whether it’s because of trauma, Burns, surgery, or other causes, scars can have an impact on our appearance and self-confidence. Are you bothered by the scars? Have you ever tried various methods, but the results were not ideal? Today, we bring you a new, scientific, and safe method called red light therapy improve scars.

Red light therapy is a non-invasive treatment that uses specific wavelengths of red light to illuminate scars, stimulating cells to produce more collagen and elastic fibers, thereby improving the appearance and texture of scars. This therapy has been proven to be very effective in improving scars.

Does Red Light Therapy Improve Scars?

How Do Scars Form?

When our skin is injured, cells called fibroblasts rush to the scene and begin producing collagen – a protein that provides structural support – to mend the wound. Initially, this collagen is disorganized and forms scar tissue. Over time, some of this collagen breaks down and the scar matures.

Mature scars form when the wound-healing process is complete. The characteristics of mature scars depend on factors like the original injury, age, genetics, and skin type. Some may appear sunken while others are lumpy or raised. The color also varies from pink to brown or white.

What Kind Of Scars Apply To Red Light Therapy?

red light therapy may help with:

  • Reducing scar size: Red light may prevent scars from becoming too large or raised by regulating fibroblast activity during the initial healing process.
  • Fading discoloration: The light has been shown to inhibit excess melanin production which can cause scars to become darkened or hyperpigmented.
  • Improving texture: Red light boosts collagen production in existing scars so they become softer, more pliable, and less rigid or lumpy.
  • Reducing itchiness and pain: The light has anti-inflammatory effects which may alleviate discomfort associated with scars.

So in summary, red light therapy may improve the appearance of scars by reducing their size, color, and texture. It may also relieve related itchiness and tenderness. This can apply to a range of scarring including acne scars, surgical incisions, cuts, burns, skin graft scars, and more.

The Key Cellular Effects Of Red Light Therapy On Scar Tissue

When the skin absorbs light energy, it triggers biochemical reactions that accelerate healing, increase collagen production, and reduce inflammation.

  •  Increases Fibroblast Activity: Fibroblasts produce collagen and elastin to repair damaged tissue. Red light boosts fibroblast activity and appropriate collagen synthesis, leading to remodeled scar tissue.
  • Reduces Inflammation: The light decreases inflammatory mediators like NF-kB and reduces the secretion of cytokines.
  •  Increases Circulation: Red light promotes the growth of new blood vessels and improves circulation, ensuring adequate oxygen and nutrients reach scar tissue.
  • Stimulates Collagen Production: Light exposure stimulates the release of growth factors like FGF-2 that support collagen production and remodeling.
  •  Inhibits Excess Melanin: Red light suppresses excess melanin created during the skin’s healing response which fades hyperpigmentation.

Thanks to these biological effects at the cellular level, red light therapy can visibly improve scar thickness, texture, firmness, and color for better overall appearance.

What Evidence Exists That?

Several reputable studies have demonstrated promising scar-minimizing results:

A clinical trial in 2014 worked with patients who had Postoperatively. After 12 sessions of red light therapy, the treatment side showed significantly improved scar color and hardness compared to the control side.

A 2018 study followed patients for 6 months after surgery who received red light therapy on their incisions. The treated scars were smoother and lighter, with increased elasticity and patient satisfaction vs untreated scars.

Multiple studies found red light decreased inflammation and accelerated wound closure times for burn injuries, which in turn limited scar formation.

While more research is needed, the overall consensus is that red light therapy shows the potential to improve scar appearance when applied correctly and consistently.

Red Light Therapy Appears To Be Safe

A major benefit of red light therapy for scars or other skin concerns is its non-invasive nature and no side effects.

Potential side effects can include:

  • Mild redness or warmth after treatment. This typically resolves within a few hours.
  • Headaches or nausea if lights enter the eyes. Always wear protective goggles.
  • Increased pigmentation if higher UV settings are used. Stick to pure red or near-infrared.
  •  Irritation from cheap LED devices does not emit true therapeutic wavelengths. Only use quality lights.

To minimize risks, speak with a doctor about appropriate treatment parameters and work with reputable brands supplying medical-grade devices that filter out UV rays. Be sure to protect your eyes, limit exposure times, and monitor your skin’s reaction.

Overall, red light therapy is widely considered very safe with minimal complications when used as directed.

How Exactly Should You Use It?

Here are some tips for an effective protocol:

  1. Consult your doctor: Discuss your scar goals, medical history, skin type, and treatment expectations.
  2. Start early for new scars: Research shows red light works best when started soon after an injury when the healing process is just beginning.
  3. Be consistent: Red light needs cumulative exposure to achieve results. Stick with regular treatments rather than sporadic sessions spread far apart. Most protocols suggest sessions 3-5 times per week.
  4. Get close: Position the light panel or wand tip very close to the skin’s surface for maximum absorption.
  5. Protect your eyes: Always use protective goggles to shield your eyes from light exposure, which could damage your vision.
  6. Moisturize after:  Hydrate treated skin with a gentle, fragrance-free moisturizer after each session to counter any dryness from the light.
  7. Use adequate settings: Your device must emit therapeutic wavelengths in the 600-950 nm range. The optimal dose will vary based on variables like scar age and skin type. Follow medical guidelines.
  8. Be patient: It takes time for red light to positively impact scar tissue, collagen production, inflammation, and melanin. Give it at least 2 months before judging results.

With the right protocol and consistent home treatments, red light therapy can help support your overall scar reduction goals.
