Keresker is the top-rated treatment for nail fungus by our experts and users for 2020.

It is the top rated because it kills nail fungus and improves appearance of nails.*

1. Kills fungus with an antifungal.
2. Users can easily scrape away infected areas of the nail.

Give Keresker a try because it is the only treatment that allows you to begin scraping away nail fungus at the end of the first week which can dramatically speed up the process of fighting nail fungus.* We believe this is the most important component to treating fungus. No other topical on this site has the ingredients capable of doing this.

When choosing a Keresker package consider getting the 3+ pack because it comes with included tools (nail scrapers and clippers), offers a discount, and a 30 day refund period. Keresker is sold only through its website keresker.com.

Our experts had a look at Keresker in our lab.

Initial Observations:

This is a white gel-like liquid topical designed for fungal nails. It has a shelf life of approximately three years.

Application:

We’ve done multiple trials of wearing it throughout the day. Keresker appeared to stay on the nail between applications. We observed the white gellatin forms a barrier (like a bandage) and a liquid layer below that on the nail. In our opinion this is extremely important as most topicals evaporate or run off the nail before the next application.

Wearing It:

It’s quite viscous but it does not run off nails. It tends to stick to the surface of the nail. On average it dried onto the nail within about 7 minutes*. Creates a plaster-like coating on the nail.

Through the Day:

We noticed that after a few days of applying that the nail became less brittle and more malleable. Similiar to a skin callus soaked in warm water. Damaged areas of the nail are easy to rub off with a finger or a tool (Keresker includes a scraper). Healthy areas seem to stay intact. We believe this beneficial because it allows the topical to soak and get to the root of the fungus.

It became clear why Keresker is rated so highly by users during our examination. It stays on throughout the day till next application unlike other topicals that evaporate or wear off prematurely. Users found that it helps the fungal nail be more malleable and easier to rub off with the included tools. It contains a powerful antifungal (Undecylenic Acid) that fights multiple types of fungus.
