Post surgical wounds are a complication of surgical procedures...
Low level laser therapy has proven research to rebuild new cells with the dermis to avoid scarring.
How LLLT Works for Wound Healing
LLLT delivers red or near-infrared light to the wound area. The light penetrates tissues and interacts with cells to stimulate biological processes, including:
1. Increased Cellular Energy (ATP Production):
• Light absorbed by mitochondria enhances the production of adenosine triphosphate (ATP), the energy source for cellular processes.
• More energy means faster cell repair and regeneration.
2. Reduced Inflammation:
• LLLT reduces pro-inflammatory cytokines and promotes anti-inflammatory factors, reducing swelling and pain around the wound.
3. Enhanced Collagen Synthesis:
• Stimulates fibroblasts to produce collagen, which is critical for wound healing and skin repair.
4. Improved Blood Flow and Angiogenesis:
• Increases circulation and promotes the formation of new blood vessels, delivering oxygen and nutrients to the wound site.
5. Accelerated Tissue Regeneration:
• Stimulates keratinocytes, fibroblasts, and other key cells involved in skin and tissue repair.
Applications of LLLT for Wound Healing
LLLT has been used effectively for various types of wounds, including:
1. Acute Wounds:
• Surgical incisions
• Traumatic injuries
2. Chronic Wounds:
• Diabetic ulcers
• Pressure sores (bedsores)
• Venous leg ulcers
3. Burns:
• Promotes healing and reduces scarring in burn injuries.
Advantages of LLLT for Wound Healing
• Non-invasive and painless.
• Can be applied to sensitive or infected areas.
• Accelerates healing, reducing recovery time.
• Minimal side effects when used appropriately.
Evidence and Research
Studies have shown:
• Significant improvement in wound closure rates.
• Reduction in infection risk due to improved circulation.
• Decreased pain and inflammation in treated areas.
