Usage and Application 🕘

Apply Kerafen topically by placing a few drops on clean, dry toenails twice daily—once in the morning and once before bed. Allow the oil to fully absorb before wearing socks or shoes, and avoid washing the treated area immediately afterward.

Consistent use over several weeks to months is necessary for best results. Many users notice improvement within 4 to 8 weeks and full effects by 90 days. Kerafen is also suitable for fingernails.

Maintain good foot hygiene and avoid combining Kerafen with other topical antifungal products unless directed by a physician.

After just a few weeks of using Kerafen, the fungus on my toenails completely disappeared. My nails, which were yellow and breaking apart, are now clear and healthy. I no longer feel the need to hide my feet and can wear flip-flops confidently. Kerafen worked remarkably fast compared to other treatments I tried.
