Diabetic foot ulcers and other diabetic wounds are a leading cause of amputation. High blood sugar impairs circulation and immune function, making wounds slow to heal and prone to infection. Red light therapy has strong clinical evidence for accelerating diabetic wound healing — and is used in many wound care clinics.
What the Research Says
Red light therapy has strong clinical evidence for diabetic wound healing:
- Multiple RCTs show faster healing of diabetic foot ulcers with RLT.
- The mechanism: RLT stimulates fibroblast proliferation, collagen synthesis, and circulation.
- Some studies show reduced amputation rates in RLT-treated patients.
- RLT is used in many hospital wound care clinics as standard therapy.
- Best results come from combining RLT with proper wound care (debridement, offloading, infection treatment).
The Diabetic Wound Protocol
- Get professional wound care first. Diabetic wounds require medical evaluation. RLT is a complement, not a replacement.
- Position the device 6 inches from the wound. Treat for 10–15 minutes per session, 1–2x daily.
- Apply sterile dressing after the session. Keep the wound clean and covered.
- Continue all medical treatments. Don't stop prescribed wound care, antibiotics, or offloading.
- Track wound size weekly. Measure length × width × depth. Look for gradual reduction.

Importance of Medical Care
Diabetic wounds require professional medical care. RLT is a complement, not a replacement. See a wound care specialist if you have:
- Any diabetic foot ulcer (open wound on the foot)
- A wound that hasn't healed in 4+ weeks
- Signs of infection (redness, swelling, pus, fever)
- Black or dark tissue (possible gangrene)
- Severe pain or numbness in the affected area
Diabetic wounds can lead to amputation if not properly treated. Don't self-treat — see a doctor.
