Nailit nail fungus light therapy device

Q: How to use?

Clean the nail thoroughly before use. Position the device over the nail so that the nail faces the transparent circular window. Press and hold the ON/OFF button for 3 seconds. The blinking green LED indicates the treatment is in progress. The device switches off automatically after exactly 7 minutes of treatment.

Our medical expert says

"The biggest challenge in treating nail fungus is that active ingredients have limited ability to pass through the nail plate and systemic drugs can have significant side effects. Nailit works with a combination of high-intensity infrared and blue light. Seven minutes per nail daily, without pain or medication — recommended as an adjunct to antifungal therapy."

Realistic expectations: It takes patience: nails grow slowly, so visible improvement requires full renewal of the nail plate – typically around six months for fingernails and possibly nine to twelve months for toenails. Daily seven-minute use matters more than anything else. Individual responses vary, and the treatment should be considered alongside antifungal therapy.
This is not the right device for you if: the cause of the nail change is unclear: not every yellowing or thickening nail is fungal – it can be due to trauma or circulation problems. In such cases sampling and diagnosis are needed first, because light treatment will not help non-fungal conditions.
Before you order: A dermatologist usually establishes the diagnosis, typically with sampling; it is worth discussing the treatment plan with them. This product description contains general advice on daily use. NOT for use under 18 years, do NOT use near the uterus during pregnancy (limb nail treatment is permitted), do not use with sunburn, during medical treatment for photosensitivity disorders, or while taking photosensitizing medication. Avoid direct eye contact with the laser and blue light.

What to use it for?

Is your toenail yellowing and thickening, and are you embarrassed to show it in sandals? ▼

Sound familiar? The beach, the pool, summer sandals — you have to hide your toes everywhere. Nail fungus is not only an aesthetic problem: without treatment it can spread to other nails and can persist for years.

Nailit's blue light (470 nm) has antimicrobial effects that can damage fungal cell walls. The infrared laser (905 nm) penetrates deeper layers and may favourably affect local circulation. Through this dual mechanism, the device may reach areas where topical creams have difficulty penetrating.

Tip: Clean the nail surface thoroughly before use. If the nail is thick, thin it down with a file — the light will penetrate more effectively.

Is your fingernail discolored and does a handshake embarrass you? ▼

Sound familiar? You extend your hand and wonder whether the other person will notice. Fingernail fungus is more visible than toenail fungus — and equally stubborn.

Fingernails grow somewhat faster than toenails, so results may become visible sooner with regular treatment. Thanks to Nailit's dual-function hinge, it comfortably fits any finger — for both hands and feet.

Tip: Improvement on fingernails can become noticeable within 3–4 months with daily regular use.

Can't take antifungal drugs because of side effects? ▼

Sound familiar? Your doctor prescribed oral antifungal tablets, but you cannot take them because of your liver values. Or they may interact with other medications. Maybe you simply don't want to take a potentially liver-affecting drug for months.

Nailit offers a drug-free solution: the laser light acts directly on the nail area and does not burden the body. Research suggests laser treatment may be especially beneficial for patients with liver disease, diabetes, or those at risk of drug interactions — as a complement to medical therapy.

Tried many treatments but the fungus always comes back? ▼

Sound familiar? Creams, lacquers, tablets — you've tried them all and the fungus returned after a few months. Unfortunately, recurrence rates for nail fungus are high: many people get reinfected after finishing treatment.

The advantage of Nailit is that after a single purchase you can use it indefinitely for prevention as well. The battery provides about 180 treatments per charge. If symptoms recur, you can restart treatment immediately — no need to visit the doctor again or buy more medication.

Frequently asked questions

Can I use it with nail polish on?

It is recommended to remove nail polish before treatment because nail color can affect laser effectiveness and reduce treatment results.

How long until the nail appearance improves?

With daily regular use, visible improvement is usually expected within 3–6 months. This varies individually because nail growth rate differs between people. Toenails grow more slowly (12–18 months for complete renewal) than fingernails.

Is the Nailit treatment painful?

No, Nailit is completely painless. The Class 1M laser device works non-thermally, so there is no heat sensation, no pain, and no side effects.

Can I use it together with antifungal medication?

Yes, Nailit can complement topical antifungal treatment. Research indicates that combining laser and topical antifungal agents is more effective than either treatment alone, as the laser may help the active ingredient penetrate the nail plate.

How often should I use the Nailit device?

Apply the device once daily for 7 minutes to each affected nail. The automatic timer stops the treatment after 7 minutes. The battery provides approximately 180 treatments per charge.

How to use? It's that simple:

Clean the nail

Thoroughly clean the nail you intend to treat. If there is nail polish, remove it — the coating can reduce treatment effectiveness.

Position the device over the nail

Place the Nailit above the nail so that the nail faces the transparent circular window. The dual hinge fits any finger or toe size.

Start the treatment

Press and hold the ON/OFF button for 3 seconds. The blinking green LED indicates the treatment is in progress.

Automatically stops after 7 minutes

The device switches off automatically after exactly 7 minutes of treatment. Then place it over the next affected nail and repeat the process.
