Treating Toenail Fungus Effectively Using UV Light Therapy at Home

Using UV Light as an Effective Treatment for Nail Fungus

Nail fungus, also known as onychomycosis, is a common condition that can cause nails to become discolored, thickened, brittle, and distorted. The toenails are more prone to fungal infections, but fingernails can also be affected. UV light treatment has emerged as a safe and effective option for killing off fungal infections under and on top of the nail.

Understanding Nail Fungus

Nail fungus is caused by tiny microorganisms called dermatophytes that feed on keratin, the protein that makes up your nails. Fungus grows well in warm, moist environments like showers, locker rooms, and the insides of shoes. Toenail fungus is much more common than fingernail fungus.

As the fungal infection worsens, nails can take on a yellow, brown, white, or green discoloration. Debris may collect under the nail, causing it to lift away from the nail bed. The nail may become brittle and crumbly or develop an irregular, distorted shape.

If left untreated, the infection can spread to other toenails or fingernails. It can also thicken and permanently damage the nail, making treatment more difficult.

The Benefits of Using UV Light

The antifungal properties of UV light have been well researched. UV waves are able to penetrate through the nail and destroy fungal overgrowth on the nail bed, nail plate, and underneath the nail.

UV nail fungus treatments offer a wide range of advantages over oral medications or topical creams:

• Non-invasive and drug-free
• Painless application
• No major side effects
• Kills fungus on nails and skin
• Requires only brief, periodic exposures
• Safe for home use
• Effective against drug-resistant fungi
• Helpful for people who can't take oral antifungals

Types of UV Lights Used

There are a few different types of UV lights that can treat nail fungus:

UVA Light

UVA light has a long wavelength that allows it to penetrate deeper into the nail bed. In lab studies, UVA light has been shown to significantly reduce fungal overgrowth on nails. However, it requires much longer exposure times than UVB or UVC light.

UVB Light

UVB light has a medium wavelength with better nail penetrating abilities than UVC light. In studies, UVB phototherapy reduced nail thickness and debris under the nail after several weeks of treatment. UVB may be used alone or paired with oral antifungals.

UVC Light

UVC light has the shortest wavelength, so it cannot penetrate as deeply into the nail bed. However, it can still kill fungi living on the nail surface and cuticle area. The major advantages of UVC light are that it works quickly and does not require the use of photosensitizing chemicals.

At-Home UV Devices

There are now affordable at-home UV nail fungus treatments that are safe and easy to use. They provide targeted light therapy that can be performed in the comfort of your home.

These devices look like small wands or boxes with UV bulbs inside. To treat each nail, you simply slide your finger or toe nail into the opening to expose it to UV rays for a short amount of time, typically ranging from 30 seconds up to several minutes depending on the device.

Sessions are done multiple times per week until the infection clears. Maintenance sessions can then be performed monthly to prevent the fungus from recurring. Many devices come with timers and safety sensors to prevent accidental overexposure.

In-Office Procedures

In addition to home use UV devices, you can also receive UV nail fungus treatments in a podiatrist's office for more powerful results.

The doctor will trim and clean your nails to remove debris. Your nails are then exposed to a specialized UV lamp for 30 minutes at a time over the course of several sessions. Some clinics may also use laser or photodynamic therapy for deeper penetration.

To enhance the effectiveness, the doctor may first apply a photosensitizing chemical to the nails. The chemical helps boost the reaction when activated by the UV light. This combined approach provides a very high cure rate.

Tips for Effective Treatment

To get the best results from UV nail fungus treatment:

• Trim nails short and file down thickened areas to allow better light penetration
• Soak feet in warm water for 10-15 minutes prior to maximize moisture
• Thoroughly dry nails and cuticles after soaking
• Apply antifungal creams after to surrounding skin to prevent reinfection
• Be patient and consistent with using UV device multiple times per week
• Disinfect home devices and shower/bath surfaces to prevent spread
• Consider combining UV and oral medication for severe cases
• Continue UV exposure 1-2 times monthly after fungus clears

Are There Any Risks?

UV nail fungus treatments are very safe when used properly and as directed. The risks are low and may include:

• Mild redness, irritation, or dryness around the nail that resolves quickly
• Photosensitivity reactions if topical chemicals are used
• Burning if UV exposure exceeds recommended lengths of time

Always thoroughly read device instructions and warnigs. Let your doctor know if you are using any photosensitizing medications. Consider goggles to protect eyes during use.

The Takeaway

Using UV light is an effective, convenient way to treat mild to moderate nail fungus. It avoids the side effects of oral medications and higher costs of in-office procedures. With consistent, proper use of over-the-counter UV devices, most cases of nail fungus can be cured. Just be patient it may take 3-9 months to see results. For severe cases, combining UV, oral meds, and professional procedures may be needed.
