Red Light Therapy for Wound Healing and Scar Reduction

Red light therapy's role in wound healing and scar reduction is among the most robustly documented in the photobiomodulation literature. From post-surgical scars to acne scarring, the evidence is strong and the mechanism is well understood.

The Healing Mechanism

When applied to wound sites or scars, red light (630–660nm) and near-infrared (850nm) light:

• Accelerate fibroblast migration and proliferation (the cells responsible for scar tissue remodeling)
• Increase vascularization (blood supply) to healing tissue
• Reduce pro-inflammatory cytokines that cause excessive scar formation (hypertrophic or keloid scars)
• Stimulate collagen type I and III synthesis for organized, functional tissue repair

Wound Healing Protocol

• Start: Once the wound is closed (not on open wounds)
• Distance: 2–4 inches for small wounds/scars
• Duration: 5–10 minutes per session
• Frequency: Once or twice daily in acute healing phase; 5x/week for chronic scarring
• Device: Handheld torch for precision; FX300 panel for larger areas

Scar Reduction Protocol

For existing scars (surgical, acne, stretch marks):

• Duration: 10–15 minutes per session
• Frequency: 5 sessions per week
• Timeline: Most users see noticeable improvement in scar texture and color at 8–12 weeks; significant reduction with continued 6-month protocols

Note: Red light therapy is not a medical treatment. Consult your healthcare provider for post-surgical applications.
