Acute Wound Healing
Source: Clinical Research Consensus
Protocol for accelerating acute wound healing using red wavelengths (630-660nm). Applied to surgical incisions, lacerations, burns, and other acute wounds. Red light promotes fibroblast proliferation, collagen deposition, and epithelialization.
Protocol Parameters
| Condition | Wound Healing |
| Wavelengths | 630nm, 660nm |
| Dosage | 2-4 J/cm² |
| Irradiance | 10-50 mW/cm² |
| Duration | 2-8 minutes depending on area |
| Frequency | Daily or every other day |
| Body Zone | variable |
| Evidence Level | Strong |
Mechanism of Action
Red light at 630-660nm is absorbed by cytochrome c oxidase, increasing ATP and ROS signaling that stimulates fibroblast proliferation, myofibroblast differentiation, and collagen synthesis. It also promotes angiogenesis (new blood vessel formation) and epithelial cell migration for wound closure.
Key Studies
- Whelan et al. (2001) - NASA study on accelerated wound healing
- Gupta et al. (2015) - PBM for wound healing systematic review
- de Freitas & Hamblin (2016) - Mechanisms of wound healing with PBM
Treatment Tips
- *Use RED wavelengths (630-660nm), not NIR, for surface wounds
- *Lower fluence (2 J/cm²) may be more effective than higher doses
- *Keep the wound clean before treatment
- *Do NOT apply to infected wounds without medical supervision
- *The biphasic dose response means more is not better
Contraindications
- !Infected wounds (treat infection first)
- !Malignant wounds
- !Active bleeding
