Laser therapy has one crucial characteristic in effectively treating Fungal infections that traditional treatment modalities lack. The ability to penetrate the nail safely and without pain to get directly to the colonisation of fungal spores beneath the nail. This enables the laser to treat the condition far more effectively than both oral antifungals and topical antifungals.

The treatment generally takes 2 minutes per nail. The laser beam is passed over the nail administering a laser wavelength that penetrates through the nail, attacking the site of the fungal infection without causing pain or damage to surrounding skin and soft tissue. The treatment is associated with a warm sensation and the patient generally describes no major discomfort.
