Toenail fungus lives beneath the nail bed, which is why surface treatments often fail. Funginix's 10% Undecylenic Acid formula is specifically designed to reach the source of the infection — the nail matrix — not just treat the surface. Undecylenic acid is an FDA-recognized OTC antifungal active with decades of documented clinical use, making it one of the most effective non-prescription options available.

Funginix combines 15 active and botanical ingredients chosen to fight fungus while nourishing the nail and surrounding skin. Tea tree oil and clove provide natural antifungal support, while aloe vera soothes irritation and lavender calms the skin around the nail bed. Vitamin E nourishes and protects the cuticle throughout the treatment process.

Every bottle of Funginix is formulated and manufactured in an FDA-registered, GMP-certified facility in the United States. Each batch undergoes independent laboratory testing to verify potency, purity, and safety before it reaches you. When you choose Funginix, you are choosing a product held to the highest domestic manufacturing standards.

Funginix is applied twice daily to the cuticle and the skin surrounding each affected nail. Allow five minutes for full absorption before putting on socks or shoes. For best results, apply to clean, dry nails and maintain consistent daily use throughout the full treatment course.
