What Laser Frequency Kills Toenail Fungus?


Laser therapy has emerged as the best toenail fungus treatment, offering a safe and non-invasive method for eliminating the infection. One of the primary advantages of lasers is their ability to target specific frequencies of light that are absorbed by the fungi responsible for the infection, without damaging surrounding tissues. So, what laser frequency kills toenail fungus exactly? Explore this question in detail.

How laser therapy works

During laser therapy, a handheld device emits concentrated beams of light onto the affected nail. Depending on the type of laser being used, different wavelengths and intensities of light can be applied. Studies suggest that certain wavelengths of light, particularly those in the near-infrared spectrum, are highly effective against toenail fungus. Specifically, lasers operating at wavelengths of around 1064 nanometers (nm) have been shown to penetrate deep into the nail plate and eradicate the fungi responsible for the infection.

Mechanism of action:

Fungi absorb light at specific wavelengths, depending on their pigments and cellular structures. The absorption of light leads to the production of heat within the cells, ultimately resulting in their destruction. At wavelengths of around 1064 nm, the fungi present in toenails selectively absorb the light, generating sufficient heat to disrupt their membranes and eliminate the infection. Importantly, the surrounding tissues remain unaffected, allowing for targeted and precise treatment.

Clinical evidence:

Several clinical studies have demonstrated the efficacy of laser therapy for treating toenail fungus. According to one study published in the Journal of Cosmetic and Laser Therapy, patients who underwent laser therapy experienced significant improvements in the clarity and thickness of their nails compared to placebo groups. Another study published in the journal Photomedicine and Laser Surgery reported similar findings, noting that laser therapy was safe, well-tolerated, and resulted in complete clearance of the infection in nearly half of the treated participants.

Availability and accessibility:

Laser therapy is widely available in many countries, including Canada, and is offered by various medical professionals, including podiatrists, dermatologists, and cosmetic surgeons. Patients interested in pursuing laser therapy should consult with a qualified healthcare provider to determine the most appropriate course of treatment based on their individual needs and circumstances. Additionally, patients should verify that the practitioner utilizes a laser approved by Health Canada for toenail fungus treatment, ensuring safety and effectiveness.
