What do gyms, swimming pool locker rooms, public bathrooms, synthetic socks, and closed-toed shoes all have in common? They’re warm, moist breeding grounds for the fungi that cause fungal nail infections.

In these environments, fungal spores can thrive for months, so if you walk barefoot and don’t wash your feet frequently, you can increase your risk of infection or reinfection.

Fungal nail infections (FNIs), also called onychomycosis, are more common than you might think. About 2% to 18% of people in the world have them — and your risk of developing an infection increases as you age. 

But that doesn’t mean you have to live with one.

If you treat early and correctly, you can quickly and completely eliminate FNIs.

RejuveNail® Anti-fungal Nail Lacquer’s Onytec technology works to eradicate nail fungal infections. It’s formulated with a fungus-killing medication called ciclopirox that penetrates the nail.

Using it is easy. Brush it onto the surface of your nail — just like nail polish, no filing required.

What is a nail fungal infection?

Several different kinds of fungal organisms can cause FNIs, which are notoriously difficult to get rid of. Trichophyton rubrum is the most common culprit, causing FNIs, as well as athlete’s foot, jock itch, and ringworm.

It has adapted to live on human skin, and research suggests that some people don’t seem to produce an immune response to it, which may make them more prone to infection.

They occur about 25 times more often in toenails than in fingernails. They also tend to happen more in older people. 

Contributing factors include poor circulation, smoking, nail trauma, prolonged exposure to fungi that cause them, suppressed immunity, and a lack of foot care.

There’s also an association between diabetes and FNIs. They’re about 2 to 3 times more common in people with the condition than those without it. 

Signs and symptoms

FNIs sometimes don’t cause any symptoms, and people assume their issues are solely cosmetic — which might be one reason many people fail to treat them early.

Over time, FNIs can lead to pain and discomfort and may even cause you to lose dexterity and sensation. And they can be more serious if you’re immunocompromised or have another health condition, like diabetes.

Symptoms of a nail fungal infection include:

  • nail discolouration (often yellow in colour)
  • nails that are thicker than usual, cracked, or fragile
  • separation of the nail from the nail bed

A fungal skin infection on the foot, especially between your toes, is another potential sign you have a fungal nail infection.

Barriers to effective treatment

Let’s be honest. It can be hard to stay consistent with your treatment. Some treatments are finicky to use, requiring multiple steps, like filing your nails every time you apply the product.

Every additional step required makes it harder to maintain treatment for the time it takes to clear the infection.

It’s difficult for classic topical medications to penetrate the nail, but Rejuvenail is formulated with the brand’s Onytec technology, which helps it penetrate deep into the nail bed.

Treatment duration is also a key factor in the successful eradication of nail fungus. FNIs are hard to clear, and it can take months of consistent treatment to completely eradicate an infection. 

Treatment options

There are lots of treatment options out there for FNIs, but they’re not created equal.

They include:

  • Topical medicated nail lacquers: These include options like RejuveNail® Anti-fungal Nail Lacquer.
  • Light therapy: Nails are treated locally with lasers or other forms of phototherapy. While this treatment option is quick, it can be painful and expensive. 
  • Nail removal: A medical professional surgically removes the nail or infected tissue or applies a chemical to the nail. This treatment is typically a last resort for severe infection. 
  • Iontophoresis: An antifungal drug, such as terbinafine, is applied to the nail, then a low-voltage electric field is applied to help it penetrate the nail. While the treatment is safe, it may cause slight discomfort and lead to skin irritation. 
  • Oral antifungals: Medications like terbinafine hydrochloride and itraconazole can be effective but have potentially harmful side effects, including headaches and liver toxicity. Doctors sometimes recommend using oral medications alongside topical ones.

Here are some foot health habits that can help you prevent infection or stop infections from coming back:

  • Wear shoes and sandals that fit and don’t cut off your circulation.
  • Wash your socks in hot water with disinfectant.
  • Wear protective footwear, like thongs, when you go to the pool and gym.
  • Keep your nails short.
  • Help your feet breathe by wearing open-toed footwear or footwear made of breathable material.
  • Avoid going barefoot in public places where the risk is high that you might get a fungal infection. These include public baths or showers, the gym, spas, and hotel rooms.
  • Spray your shoes every time you use them with a topical antifungal spray or a UV shoe sanitizer.

How does it work?

RejuveNail® Anti-fungal Nail Lacquer sticks to the keratin structure of your nail, and as it dries, a special delivery system helps the product penetrate the whole nail. The active compound spreads into the sides of the nail, the nail bed, and the cuticle, delivering it straight to the site of the infection. 

The medication sticks irreversibly to the cell walls of fungal cells and inhibits them from taking up the nutrients they need to stay alive and multiply.

And it works.

But it’s important to note that Rejuvenail can’t work unless you do. You need to apply it daily for at least 6 months and up to a year.

Sticking to a treatment plan can take time and effort. But RejuveNail® Anti-fungal Nail Lacquer makes it as easy as possible.

It’s easy to use with no filing required. Just apply it straight to affected nails once a day — unlike other treatments, which typically require twice-daily applications. The Onytec technology helps the formulation penetrate your nail and kill those fungi fast, for minimum treatment duration, so you don’t have to wait longer or go through multiple treatment phases before you notice results. 

And it’s clinically proven to improve and eliminate FNIs.

Who shouldn’t use it?

In case you’re wondering, RejuveNail® Anti-fungal Nail Lacquer has been shown to be safe for adults.

It acts on the nail itself, and the body absorbs negligible levels and eliminates them within 12 hours. Researchers have found it poses a very low risk in humans.

That said, if you fall into one of these groups, it may be best to avoid treating with RejuveNail®:

  • If you have hypersensitivity to ciclopirox or any of the ingredients in the lacquer.
  • If you’re pregnant or breastfeeding.
  • If you’re younger than 18 years, since there’s not enough research in this age group.

Bottom line 

RejuveNail® Anti-fungal Nail Lacquer effectively kills and protects against tough fungal nail infections — because life’s more fun without fungus.
