What are scars?
Scars form when the skin repairs itself after an injury. During this process, your body creates new connective tissue, which often looks different from the original skin. As a result, scars can appear thicker, redder, darker, or more sunken.
Types of scars
- Atrophic scars: often caused by acne; small indentations in the skin.
- Hypertrophic scars: raised, red scars that stay within the original wound edges.
- Keloids: scars that grow beyond the original wound.
- Surgical scars: straight lines that may appear red or firm.
- Burn scars: can be tight, thick, or discolored.
How does red light help with scars?
Red light therapy uses wavelengths around 630–660 nm (and often near‑infrared around 830 nm) to penetrate deep into the skin. There, it supports the processes essential for scar recovery:
- More cellular energy (ATP): Mitochondria receive a boost, helping cells repair faster and build new tissue more effectively.
- Stimulation of collagen and elastin: Helps scars become smoother, softer, and less visible.
- Improved blood flow: More oxygen and nutrients reach the damaged area, speeding up recovery.
- Reduced inflammation: Red light calms redness and swelling, making scars less noticeable.

What does research say?
There is extensive research on how red light supports skin regeneration. These are the key findings so far:
Faster wound healing
Photobiomodulation studies show that red and near‑infrared light increase cellular activity, stimulate fibroblasts, and support the formation of more organized collagen.
(NCBI: PMC8919713, PMC4126803, PMC8240139)
Reduced inflammation
Studies show that red light can reduce pro‑inflammatory processes, helping to decrease redness and swelling around scars.
(NCBI: PMC4387504)
Improved circulation
Research indicates that red light can enhance microcirculation, improving tissue nourishment.
(NCBI: PMC5988166)
Support for collagen
Reviews describe how red light helps form stronger, more flexible collagen, making scars less rigid and visible.
(NCBI: PMC5523874, PMC4148276)
How to use red light devices?
- Distance: keep the panel 10–30 cm from your skin.
- Duration: 10–20 minutes per session.
- Frequency: 3–5 times per week for best results.
- Eye protection: always wear protective goggles, especially with powerful panels.
- Fresh scars: wait until the wound is fully closed before starting.
- Patience: improvements happen gradually; consistency is key.
Conclusion
Red light therapy is a gentle, non‑invasive way to soften scars and support the skin’s natural healing process. Research shows promising results, especially in wound healing, collagen production, and inflammation reduction.
The panels are not a miracle cure, but they are an effective addition to a smart skincare routine if you’re looking for a safe, natural way to make scars less visible.
