Fingernails Toenails Fungus Cold Laser. FEATURES: HNC 905nm Laser Therapy Device to Treat Nail Fungal Infections (Onychomycosis), Which Combines Pulse Laser Radiation and Blue Light Energy, Resulting in a Synergetic Therapeutic Effect. Laser Irradiation Will Penetrate the Infected Nail Plate and Will Target Causative Pathogens Residing on the Nail Bed. As a Result, the Infection Will Be Greatly Alleviated and Gradually Eliminated. Lasers Produce Coherent Light Energy of Sufficient Strength and of a Specific Wavelength Which when Projected into Tissue is Differentially Absorbed by the Target Material, Producing Heat and Hence Tissue Destruction. Other Tissue Components Are Unaffected and So Spared.
