Low-Level Laser (Light) Therapy (LLLT) in Skin

This 2013 clinical review examined the role of low-level laser/light therapy (LLLT), also called photobiomodulation, in dermatology and skin-related healing. The paper reviewed how red and near-infrared light interacts with skin tissue and explored its therapeutic applications for healing, inflammation, and skin restoration.

Key Findings

• LLLT works by delivering non-thermal red and near-infrared light that is absorbed by cellular chromophores, especially within mitochondria, helping stimulate biological activity.
• Reported effects included:
  • Enhanced wound healing
  • Reduced inflammation
  • Improved tissue repair and regeneration
  • Pain relief
  • Potential benefits for skin rejuvenation and dermatologic recovery
• The review discussed PBM use in conditions such as:
  • Wounds and ulcers
  • Inflammatory skin disorders
  • Scar healing
  • Skin rejuvenation and restoration

Clinical Takeaway

This review supports that LLLT/photobiomodulation may help stimulate skin healing, reduce inflammation, and improve tissue recovery, making it a promising non-invasive approach in dermatology and regenerative skin care. However, outcomes depend on wavelength, dose, and treatment parameters.
