Red Light Therapy for Scars (Hypertrophic / Keloid)
Hypertrophic scars and keloids result from abnormal wound healing with excessive collagen deposition. They can be painful, itchy, and cosmetically distressing.
Prevalence: Hypertrophic scars affect up to 70% of surgical wounds; keloids in 5-15% of wounds in predisposed individuals
How Red Light Therapy Helps
PBM modulates the inflammatory phase of scar formation, promotes organized collagen deposition, and reduces myofibroblast activity. Early treatment produces better outcomes than treating established scars.
