Research has shown that red and near-infrared light can accelerate wound healing and improve scar appearance. Studies indicate that RLT helps by increasing circulation, reducing inflammation, and stimulating the production of new skin cells.
Key Findings from Multiple Studies:
- A 2013 study found that patients with diabetic ulcers treated with red light (660nm) healed significantly faster compared to those without light therapy.
- A 2017 clinical trial showed that post-surgical scars treated with near-infrared light (810nm) became less visible and had better tissue regeneration over time.
- A 2019 study found that RLT applied immediately after injuries reduced swelling and improved healing speed in burn wounds.
- Research suggests that red light enhances collagen production, making scars smoother and less noticeable over time.
Implications:
These studies suggest that red light therapy between 630-850nm can promote faster wound healing, reduce scar visibility, and improve overall skin repair. Regular use may be beneficial for individuals recovering from cuts, burns, ulcers, or surgical scars.
