What are scars?
Scars form when the skin repairs itself after an injury. During this process, your body creates new connective tissue, but it often looks different from the original skin. As a result, scars may be thicker, redder, darker or located deeper in the skin.
What are scars?
- Atrophic scars: often caused by acne; pits or depressions in the skin.
- Hypertrophic scars: raised, red scars that remain within the edges of the wound.
- Keloids: scars that grow beyond the original wound.
- Surgical scars: straight, often red or hardened lines.
- Burn scars: may be tight, thick or discolored.
How does red light work for 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 the exact processes that are important for scar healing:
- More cellular energy (ATP): The mitochondria receive a boost, allowing cells to recover faster and new tissue to be built more effectively.
- Stimulation of collagen and elastin: This helps make scars smoother, flatter and less visible.
- Improved blood flow: More oxygen and nutrients reach the damaged area, which speeds up recovery.
- Less inflammation: Red light calms redness and swelling, making scars less noticeable.

What do we know from research?
Extensive research is being conducted into how red light helps the skin recover. These are the most important findings so far.
Faster wound healing
Photobiomodulation research shows that red and near-infrared light increases cellular activity, stimulates fibroblasts and helps form better-organized collagen, which is essential for smoother scars.

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

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

Support for collagen production
Reviews describe how 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 when using powerful panels.
- Fresh scars: wait until the wound is completely closed before starting.
- Patience: scars improve gradually, so consistency is important.
Conclusion
Light therapy is a gentle, non-invasive way to soften scars and support the skin’s natural recovery. Science shows promising results, particularly in the areas of wound healing, collagen production and reducing inflammation.
The panels are not a miracle cure, but they 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.
