How light therapy works for nail fungus
Nail fungus thrives in dark, moist environments. Light therapy disrupts fungal cells using:
- Laser (Near-Infrared or Diode Laser) – Penetrates the nail to destroy fungal cells without damaging skin.
- UV Light (Ultraviolet) – Kills fungus but requires caution due to skin damage risks.
- Red & Blue LED Light – Less intense but may help with mild cases.
Science Behind It
- Light energy is absorbed by fungal cells, damaging their DNA and stopping reproduction.
- Some devices also generate mild heat, further weakening fungus.
- Works best when combined with proper nail hygiene.

Step-by-Step Light Therapy Treatment Process
Step 1: Prep Your Nails
- Soak feet in warm water + Epsom salt (softens nails).
- Trim and file infected nails (helps light penetrate better).
Step 2: Apply Light Therapy
- Follow device instructions (usually 2-3 sessions per week).
- Wear protective goggles if using UV light.
Step 3: Post-Treatment Care
- Keep feet dry and clean.
- Use antifungal sprays or essential oils (tea tree, oregano) for extra protection.
How Long Until Results?
- 4-8 weeks for visible improvement.
- 3-6 months for full nail regrowth (since nails grow slowly).
