Key Takeaways
ToeFX is an FDA-cleared, LED-based photodynamic light therapy system specifically designed to treat toenail fungus beneath the nail, where topical products can't reach. A photoactive blue serum (FungalBlue) is applied to prepared nails, then a light device is positioned over the toes for about 10 minutes. The serum binds to fungal cells and makes them vulnerable to the light. Sessions are painless and take place every two weeks. Patients who haven't responded to topicals and want to avoid oral medication may be good candidates for this cutting-edge treatment.
Brittle or discolored toenails aren't just a cosmetic concern. For many people, toenail fungus isn't just a source of embarrassment, but a cause of real discomfort. You might have picked up an over-the-counter treatment or two and applied it faithfully for months, only to find the problem is just as bad as it started.
You're not alone in that experience. Toenail fungus, or onychomycosis, is one of the most common nail conditions treated by podiatrists. It tends to be persistent because the infection lives beneath the nail, where topical products struggle to penetrate. The Foot Institute offers a more modern approach that addresses this challenge directly.
One treatment option our El Paso podiatrists provide is ToeFX light therapy, a clinically tested toenail fungus treatment that works at the source of infection without the risks associated with oral antifungal medications.

What Is ToeFX Light Therapy?
The cutting-edge ToeFX treatment has been cleared by the FDA and was developed to use light for treating fungal infections. It penetrates the nail to focus on underlying fungal cells and disrupts their ability to reproduce. Over the course of treatment, healthy nail tissue replaces the infected growth.
A key part of what makes ToeFX work is a photoactive blue serum called FungalBlue. When applied to the nail before each light treatment, it binds to fungal cells and makes them vulnerable to the specific wavelengths of light the device emits. The combination of the serum and the light is what drives results.
Each in-office ToeFX session takes approximately 10 minutes per foot. There is no pain involved. The blue serum fades naturally within seven to 10 days after each visit, and there are no activity restrictions following treatment.
How a ToeFX Treatment Session Works
Before each treatment session, one of our El Paso podiatrists will debride the affected nails. This means carefully filing them down so the light can reach the fungus below the nail surface. It's a quick step, and typically involves no pain or discomfort.
Once the nails are prepared, the FungalBlue serum is applied, and the ToeFX therapy light is positioned over your toes for the treatment period. That's it—you're done for the visit and ready to get back on your feet.
Most patients complete eight to 12 sessions over a six-month period, with visits scheduled every two weeks during the active treatment phase. After the infection clears, maintenance visits every six to eight weeks can help prevent unpleasant toenail fungus from returning. Our team will work with you to build a schedule that fits your life and supports long-term results.
Common Questions About ToeFX
- Is ToeFX painful? No. The treatment session is completely painless. Most patients find it unremarkable. You simply sit, receive the treatment, and then leave.
- Will the blue serum stain my skin or nails? The FungalBlue serum does leave a blue tint on the nails immediately after application, but it fades naturally within seven to 10 days.
- How long until I see results? Because nail growth is gradual, visible improvement typically becomes apparent over several months. The most noticeable changes appear as healthy new nail grows in from the base.
- What can I do to prevent toenail fungus from coming back? Keeping feet clean and dry, wearing moisture-wicking socks, choosing well-fitted shoes, and avoiding walking barefoot in public areas like locker rooms and pool decks all reduce reinfection risk. Maintenance visits after treatment also play a key role in maintaining healthy feet.
How ToeFX Compares to Other Toenail Fungus Treatments
If you've researched toenail fungus treatment before, you've likely come across a few standard options. Here's a straightforward look at how they compare.
Either over-the-counter or prescription-strength topical treatments may require daily application for up to a year. Clinical clearance rates are typically very low, which means most patients using these medications may see limited improvement or no improvement at all.
Anti-fungal oral medications can be effective, but they often require blood monitoring due to the risk of liver toxicity and can also cause gastrointestinal side effects. It's not a good option for patients with certain health conditions or those taking specific medications that may not react well.
Laser treatments are drug-free and performed in-office, making them a reasonable option for some patients. Results vary based on infection severity, nail thickness, and individual growth patterns.
For patients who want a highly effective, low-burden toenail fungus treatment, ToeFX offers a meaningful advantage over most alternatives.
What to Expect as Your Nails Heal
Toenail fungus doesn't clear overnight, and toenails grow slowly, averaging about half a millimeter per month. This means results are gradual and become more visible over time as healthy nail tissue grows in from the base. Most patients begin to notice clearer nail growth within the first several months of treatment.
Consistency matters throughout this process. Missing scheduled sessions can give the fungus an opportunity to reestablish itself, which is why staying on track with your treatment schedule is important. Between visits, our team will give you practical guidance on habits that support your results: things like washing socks and linens at high temperatures, disinfecting shoes, and keeping nail clippers separate from others in your household to prevent reinfection.
Once treatment is complete, periodic maintenance visits help protect the results you've worked for.
