Scar Reduction Protocol
Source: Clinical Research
Protocol for reducing the appearance and texture of scars, including hypertrophic scars and early keloids. Combining red and NIR wavelengths addresses both the superficial scar tissue and deeper collagen disorganization.
Protocol Parameters
| Condition | Hypertrophic Scars / Keloids |
| Wavelengths | 630nm, 660nm, 850nm |
| Dosage | 3-6 J/cm² |
| Irradiance | 20-50 mW/cm² |
| Duration | 10-15 minutes |
| Frequency | 3-5x per week for 12+ weeks |
| Body Zone | variable |
| Evidence Level | Moderate |
Mechanism of Action
PBM modulates the inflammatory phase of scar formation, promotes organized (rather than disorganized) collagen deposition, and reduces myofibroblast activity responsible for scar contracture. In established scars, it promotes collagen remodeling toward a more normal tissue architecture.
Key Studies
- Carvalho et al. (2010) - PBM for keloid and hypertrophic scar management
- Barolet & Boucher (2010) - LED for scar prevention
Treatment Tips
- *Start treatment as early as possible after wound closure
- *For established scars, expect slower but gradual improvement
- *Combine with silicone sheets or gel for enhanced results
- *Can be used alongside scar massage techniques
Contraindications
- !Active wound infection
- !Malignant skin changes in scar tissue
