What are scars?
Scars form when the skin repairs itself after a wound. During this process, your body produces new connective tissue, but it often looks different from the original skin. As a result, scars can be thicker, redder, darker, or even deeper.
Types of scars
- Atrophic scars: often caused by acne; small pits or indentations in the skin.
- Hypertrophic scars: thickened, red scars that remain within the wound edges.
- Keloids: scars that grow beyond the original wound.
- Surgical scars: straight, often red or hardened lines.
- Burn scars: can be tight, thick, or discolored.
How does red light work on 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 stimulates exactly the processes important for scar healing:
- More cellular energy (ATP): The mitochondria get a boost, allowing cells to heal faster and new tissue to be built better.
- Stimulation of collagen and elastin: This helps make scars more flexible, smoother, and less visible.
- Improved blood circulation: More oxygen and nutrients reach the damaged area, speeding up recovery.
- Less inflammation: Red light soothes redness and swelling, making scars less noticeable.

What do we know from research?
There is extensive research on how red light helps the skin heal. These are the main findings so far.
Accelerated wound healing
Photobiomodulation research shows that red and near-infrared light increases cell activity, stimulates fibroblasts, and helps form better-organized collagen, essential for smoother scars.

Reduced inflammation
Studies show that red light can inhibit pro-inflammatory processes, reducing redness and swelling around scars.

Improved blood circulation
Studies show that red light can inhibit pro-inflammatory processes, reducing redness and swelling around scars.

Support of collagen
Reviews describe that red light helps form stronger, more flexible collagen, making scars less stiff and visible.

How to use red light lamps?
- Distance: keep the panel 10–30 cm from your skin.
- Duration: 10–20 minutes per session.
- Frequency: 3–5 times per week for optimal results.
- Eye protection: always wear protective glasses, especially with powerful panels.
- Fresh scars: wait until the wound is fully closed before starting.
- Patience: scars improve gradually; consistency is important.
Conclusion
Light therapy is a gentle, non-invasive way to soften scars and support the skin’s natural healing. Science shows promising results, especially in wound healing, collagen production, and inflammation reduction.
The panels are not a miracle cure but are an effective addition to a smart skincare routine, especially if you are looking for a safe and natural way to make scars less visible.
