Kerafen Reviews: An Antifungal Treatment For Toenail Health!

Toenail fungus, or onychomycosis on toes is a common condition that affects about 10-20 percent of the population in the United States. It is a fungal infection on toenails that causes brittle, and discolored nails. The condition is more prevalent in individuals who are older than 60 years of age.

The last summer after I returned from my vacation, I started to see a color change in my pinky toenail. The nails were crumbling, and it had a disgusting yellow-brown color to it. Concerned, I consulted a friend of mine working in healthcare who diagnosed me with toenail fungus. 

In my search for a solution, I came across several treatments, but Kerafen stood out because of its overall customer ratings and positive reviews. Karefen is a topical supplement that works as a toenail fungus remover.

The supplement claims that it can treat and prevent toenail fungus, improve the appearance and color of the nails, and support stronger and healthier nails. They also claim that it works by addressing the root cause of toenail fungus.

So, I bought the supplement and have been using it for the last three months. In this Kerafen review, I will be revealing my truthful experience with the supplement, so that you don’t have to make a blind decision.

What is Kerafen?

Kerafen is an antifungal formula used for treating toenail fungus. The supplement is made from naturally available and synthetic ingredients such as tea tree essential oils, aloe vera leaf, sweet almond oil, etc. According to the Kerafen manufacturer, this unique blend of nature-based ingredients can help support the root cause of toenail fungus, which is the defense mechanism of the toenail fungus that shields itself by making a protective layer called biofilm around it. 

From what I have understood from the Kerafen official website, it is suitable for men and women regardless of age. It is a topical solution and one bottle contains 0.5 fl. oz that is 30 ml. A Kerafen bottle can last for about 30 days of daily use and it costs about $49/bottle.

According to the manufacturer, Karafen usage in addition to a healthy lifestyle can lead to improved toenail health, better appearance and strength of toenails, and prevent fungal infection. 

While these claims were intriguing, I did my due diligence by doing in-depth research about the supplement, to ensure safety and potency. In the coming segments, I will be sharing what my research and first-hand experience have taught me about Kerafen. 

How to benefit the most from Kerafen?

Kerafen nail health solution is designed for topical application to eradicate fungal infestation on toenails. From my experience of using the supplement, I have come to understand that you can adapt certain things to your lifestyle to get the best results from it. The beneficial changes include: 

  • Clean the affected area with soap and water and dry it before applying Karen 
  • Better to use the supplement after showering 
  • Follow a balanced diet to support better nutrition 
  • Wear socks that can absorb sweat

✔️ Improved anti-inflammatory response: Kerafen contains a good amount of anti-oxidants and antiinflammatory agents which can help heal the wounds in the affected area. 

How to use Kerafen?

Kerafen anti-fungal serum is a topical solution that is used for toenail fungus. If you are experiencing the symptoms of toenail fungus such as discoulored, brittle, and ragged toenails, apply the solution on the affected part and skin around it once every day.

Using the supplement after showering is best to support better absorption. I have found that applying Kerafen drops at night can be better to ensure optimal results. The supplement is not safe for oral consumption. It may cause serious side effects if ingested orally. 

Kerafen ingredients list

According to the manufacturer, the Kerafen toenail health support formula is a blend of naturally available ingredients that have been shown to inhibit and prevent toenail fungus. I have analyzed these Kerafen ingredients in the light of scientific research. Sharing my findings below: 

  1. Undecylenic Acid USP

    This is a chemical compound that is used in cosmetic and pharmaceutical products. It has antimicrobial properties that can treat itching, irritations, and infections on the skin. Research published in ResearchGate has provided insights into the Undecylenic Acid’s antifungal activity.

    It is a herbal compound derived from a plant native to Australia called, Melaleuca alternifolia. It has antibacterial, anti-inflammatory, antiviral, and antifungal properties which makes it beneficial for toenail fungus, acne, athlete’s foot, etc. A WebMD article suggests that the tea tree essential oil can help treat nail fungus. However, more research is needed to determine the tea tree essential oil’s complete effects.
  3. Aloe Vera Leaf

    It is a medicinal plant used for treating conditions related to skin and hair. It can nourish skin, promote healing, and enhance the immune system.

Is Kerafen safe?

There are no safety warnings on the Kerafen official website, which means that the supplement can be safe for most individuals. I had no problem believing in the safety of the supplement because it is made from natural ingredients. In my personal experience, I have not encountered any safety issues while using the Kerafen supplement. As long as you stick with the instructions given on the label, Kerafen can be a safe choice. 

Who is it for?

Kerafen is a supplement designed for people who are affected by toenail fungus. If you are experiencing brittle and ragged toenails caused by fungal growth, the supplement can help you regardless of your age, or gender. It works by combating the major cause of toenail fungus. It can also improve the appearance and color of the toenails. As a 53-year-old male, the supplement has worked for me. 

How does Kerafen work?

Kerafen toenail fungus remover is a blend of natural-based ingredients that can help eradicate fungal infections. It is designed to address a new scientific discovery that found the root cause of toenail fungus.

According to new scientific discoveries, the cause of stubborn toenail fungus is opin pointed to the protective layer that the fungus makes over them. This protective layer is called biofilms. Kerafen works by depleting this protective layer and combatting the fungal infection. 

My research suggests that Kerafen supplement contains several antimicrobials including undecylenic acid USP, and tea tree essential oil, which can create a hostile environment for fungus and reduce its growth. In addition to combating fungal infection, the supplement can also improve skin and nail health by providing nourishment to the cells. This is achieved by using herbal ingredients such as aloe vera that can help hydrate and nourish the cells. 

Moreover, the supplement can also support wound healing because it contains several antioxidants and anti-inflammatory agents. By improving wound healing, Kerafen can support an overall improvement in the appearance, color, and discoloration of the nails. So, by using the supplement, you can support healthy nail growth, improve the health of the skin around it, and prevent fungal growth. 

Alternative options for Kerafen

To be real, there are a multitude of alternative supplements available on the market. But very few come close to the popularity and customer ratings that Kerafin has. After hours-long screenings, I have narrowed it down to 2 natural supplements. They are: 

  1. Metanail Serum Pro

    It is a 20-in-1 nail & feet essential formula made with ingredients that are 100% free of harmful chemicals. It is GMO-free and made in an FDA-approved facility in the United States.

Keep it away from children and, after using the supplement thoroughly wash your hands with soap and water.
