Erases Fungus in Just 60 Seconds
Kerafen's primary action comes from Undecylenic Acid, a powerful fatty acid recognized by health authorities for its antifungal properties. It works by disrupting the fungal cell membrane, which stops the fungus from growing, reproducing, and spreading under the nail.
The formula is enhanced with a complex of essential oils known for their natural antimicrobial effects, including Tea Tree Oil, Manuka Oil, and Clove Oil. These oils work in synergy to create an environment that is hostile to fungus, providing a secondary defense and helping to soothe the surrounding skin.
To ensure the active ingredients reach the source of the problem, Kerafen uses a blend of penetrating carrier oils like Flaxseed, Almond, and Jojoba Oil. These oils help transport the antifungal compounds through the dense nail plate to the nail bed where the fungus resides, while also moisturizing and conditioning the brittle nail.
Finally, ingredients like Aloe Vera and Vitamin E help to calm the irritation, redness, and itching associated with fungal infections. This supports the skin's natural healing process, restoring a healthier appearance to the nail and surrounding tissue as the infection clears.
vs Oral Antifungals (e.g., Lamisil Rx)
Works topically directly on the nail, avoiding the potential for systemic side effects often associated with oral prescription medications.
vs Standard OTC Antifungal Creams
Features a specialized oil-based delivery system designed to penetrate the tough nail plate, a common barrier for water-based creams.
vs Tea Tree Oil (as a single ingredient)
Combines natural tea tree oil with undecylenic acid, a clinically recognized antifungal agent, for a more potent, multi-angle approach.
vs Clinical Laser Treatments
Offers a non-invasive, daily at-home solution without the high cost, time commitment, and multiple appointments of laser procedures.
