Effect of red and near-infrared wavelengths on low-level laser (light) therapy-induced healing of partial-thickness dermal abrasion in mice

This in vivo study examined the effects of red and near-infrared wavelengths in low-level laser therapy (LLLT) on the healing of partial-thickness dermal abrasions in mice. The results showed that both red and near-infrared light significantly accelerated wound healing, enhancing re-epithelialization and collagen deposition compared to controls. These findings suggest
