Toenail fungus is a common condition that causes thickened, discolored, and separating nails. It is a fungal infection that affects the nail bed, nail plate, and surrounding skin. Several treatment options are available, including topical antifungal creams, oral medications, and nail removal in severe cases. Laser therapy has emerged as a newer treatment option and is reported to be highly effective in killing the fungus and promoting healing. It uses concentrated light to penetrate the nail and destroy the fungus, but the exact mechanism is not fully understood. While it is considered safe, there are some side effects, and multiple sessions are usually required for optimal results.

Laser treatment for nail fungus: how it works
Laser treatment for nail fungus is a newer treatment option that uses concentrated light to kill the fungus and prevent its growth. The treatment is typically carried out by a podiatrist or a board-certified dermatologist and can be done in about 30 minutes. It is considered safe and has a low risk of side effects, although some patients may experience pain or bleeding in the area around the nail.
The exact mechanism of how laser treatment removes nail fungus is not yet fully understood. However, some experts believe that the light penetrates the nail and is absorbed by the fungus, causing damage or death to the fungal cells. The heat produced by the laser also has a sterilizing effect, which helps prevent new fungal growth. When the laser is targeted at the area of infection, the heat inhibits the growth of the fungus and destroys it.
There are several types of laser treatments available, including some that use light and others that use carbon dioxide (CO2). Laser devices emit pulses of energy that produce heat. For the treatment of nail fungus, the laser is directed so that the heat penetrates the toenail and reaches the nail bed, where the fungus is located. CO2 lasers or yttrium-aluminum-garnet (YAG) lasers with wavelengths of 870 nm, 930 nm, or 1320 nm are typically used for this purpose.
Laser treatment for nail fungus generally requires multiple sessions for it to be effective. It may take three to 18 months of consistent treatment to see results. The number of treatments needed can vary depending on the severity of the infection and the type of laser used. While laser treatment has shown promising results, more research is needed to establish it as a standard treatment option.

Effectiveness of laser treatment
Laser treatment for toenail fungus is a newer treatment option that uses concentrated light to kill the fungus and prevent its growth. It is considered safe and has a low risk of side effects, although some patients may experience pain, bleeding, or burning during or after the procedure. Laser treatment is particularly beneficial for individuals with diabetes, older individuals with drug intolerance, and patients with liver and kidney problems.
Several types of laser treatments are available, including some that use light and others that use carbon dioxide (CO2). Laser devices emit pulses of energy that produce heat, which is directed to penetrate the toenail and reach the nail bed where the fungus is located. The heat breaks down the infected tissue, destroying the fungus and the surrounding skin and nails. It also has a sterilizing effect, preventing new fungal growth.
The effectiveness of laser treatment for toenail fungus varies, and it may take multiple sessions for the treatment to be successful. Some studies have shown promising results, with a high success rate and complete cure in some cases. For example, in one study, 50% of patients achieved a "complete cure" after three sessions of CO2 laser treatment. Another study by Landsman and colleagues found that 65% of treated toenails attained at least 3 mm of clear linear nail growth after four exposures to an 870/930-nm laser. However, other studies have reported conflicting results, and the published evidence to date does not conclusively prove that laser treatment improves health outcomes in patients with onychomycosis.
The number of treatment sessions required can range from one to three or more, depending on the severity of the infection and the type of laser used. Each session typically lasts about 30 minutes, and there is usually no recovery time needed afterward. However, it may take a few months to notice the results of the treatment as patients will need to wait for their nails to grow out.
While laser treatment for toenail fungus can be effective, it is important to note that it may not work for everyone, and there are alternative treatment options available, including topical antifungal creams, oral medications, and nail removal in severe cases.

Safety and side effects
Laser toenail fungus removal is considered a safe procedure with minimal side effects. It is approved by the U.S. Food and Drug Administration (FDA) to treat toenail fungus. The treatment is non-invasive and does not require any recovery time, allowing individuals to return to their usual activities immediately after each session.
While the procedure is generally safe, some mild side effects may occur. Some people may experience a burning sensation or pain during the treatment. In one study, subsequent haemorrhage occurred after treatment, but it subsided within two weeks. Reducing the laser energy density can prevent bleeding. The majority of patients report that the burning sensation is tolerable, and there are no serious adverse reactions.
The safety of laser toenail fungus removal is further supported by the lack of systemic side effects and drug interactions. This makes it a preferable alternative to oral medications, which carry the risk of liver damage, kidney problems, and gastrointestinal reactions. Laser treatment may be safer for children, pregnant people, and those with underlying conditions.
However, it is important to note that there is limited research on the long-term safety of laser toenail fungus removal. While it has been praised for its effectiveness, the American Academy of Dermatology Association (AAD) notes that more research is needed to establish its safety conclusively.
When considering laser toenail fungus removal, it is essential to consult with a qualified and experienced dermatologist or podiatrist. They can provide guidance on the safety and effectiveness of the procedure for your specific case.

Alternative treatments
Toenail fungus causes thickened, discolored, and separating nails. While laser therapy is a newer treatment option, there are several alternative treatments for toenail fungus that can be explored. It is important to note that while home remedies are available, they may not work for everyone, and severe or persistent fungal infections require medical attention. Here are some alternative treatment options:
- Topical Antifungal Creams: These are creams that are applied directly to the affected nail as directed by a doctor. An example of a topical ointment is Vicks VapoRub, which contains camphor and eucalyptus oil, ingredients that may help treat toenail fungus.
- Oral Medications: Antifungal medication in the form of capsules or tablets can be prescribed by a healthcare professional. Examples include fluconazole (Diflucan) and terbinafine (Lamisil). These medications can resolve the infection faster and more effectively, but they may also cause side effects such as an upset stomach, dizziness, severe skin problems, or jaundice.
- Combination Therapy: This approach combines the use of both topical creams and oral medications to treat the infection.
- Nail Removal: In severe cases or when the fungus does not respond to other treatments, a healthcare professional may recommend surgically or chemically removing the nail.
- Home Remedies: These include soaking the affected foot in Listerine mouthwash, which has antibacterial and antifungal properties due to its menthol, thymol, and eucalyptus content. Another home remedy is the use of garlic extract, which is believed to have antifungal properties. However, more research is needed to confirm its effectiveness. Apple cider vinegar is also suggested by some sources due to its antimicrobial properties, although scientific evidence is lacking.
- Foot Hygiene and Care: Practicing good foot hygiene, such as washing and drying the feet daily, especially between the toes, can help prevent and manage toenail fungus. Choosing breathable footwear, changing socks regularly, using antifungal powder in shoes, and trimming nails properly are also recommended.

Professional vs. home laser treatment
Laser treatment is a newer option for treating toenail fungus. It uses concentrated light to kill the fungus and prevent its growth. The treatment can take about 30 minutes, and patients usually do not need any recovery time. However, it can take up to 2 months to see the results.
Professional laser treatment is highly effective in killing the fungus and promoting healing. It is performed by a podiatrist, who can evaluate your condition and recommend the best treatment options. This option is ideal for people with severe pain or discomfort, black nail fungus, or other conditions that put them at risk for foot infections, such as diabetes.
Home laser devices are also available for treating toenail fungus. These devices are not as powerful as professional ones, but they can still be somewhat effective in reducing symptoms and promoting healing. Benefits of home laser treatment include the convenience of being able to use the device at home and lower cost compared to professional treatment. However, it's important to choose a reputable device and follow the instructions carefully. Additionally, home laser treatment may not work for all types of fungal toenails.
While laser treatment shows promising results, it is still a relatively new method, and more research is needed to establish it as a standard treatment option.
