Yes. Funginix contains 10% Undecylenic Acid, an FDA-recognized OTC
antifungal active ingredient with decades of documented safe use. All
botanical ingredients are independently tested for purity and
potency. If you are pregnant, nursing, diabetic, or have a health
condition affecting circulation, consult your doctor before use.

Apply Funginix twice daily — morning and night — to clean, dry nails and surrounding skin. Use the built-in precision brush to apply a thin, even layer directly to the affected nail, working it into the cuticle and underneath the nail edge. For best results, maintain consistent daily application and keep nails trimmed short.

Results vary by the severity of the infection and individual response. Most
users begin to see improvement within 2–4 weeks as healthier nail
growth emerges at the base of the nail. Full clearing of a toenail
fungus infection typically requires 10–12 weeks of consistent
twice-daily application, as the healthy nail must grow out fully.
Patience and consistency are key — the existing infected nail must
grow out and be replaced.

Yes. While Funginix is formulated with toenails in mind, it can be applied
to fingernails affected by fungal infection using the same
twice-daily method. Apply to the cuticle and skin around each
affected nail and allow to absorb fully.

Most OTC topical antifungals use tolnaftate or clotrimazole as their
active ingredient. Funginix uses 10% Undecylenic Acid — a fatty
acid derived from castor oil with strong antifungal properties and a
long safety record. Funginix also combines this with 14 additional
botanical ingredients (tea tree, clove, aloe, lavender, Vitamin E)
that support nail health and soothe the surrounding skin during
treatment. Oral Lamisil (terbinafine) requires a prescription and
carries systemic side effects; Funginix is applied topically and
formulated for daily OTC use.

Recurrence is common because toenail fungus thrives in warm, moist environments.
Common re-infection sources include contaminated footwear, shared
showers or locker rooms, and damp socks. To reduce recurrence:
disinfect old shoes, use moisture-wicking socks, keep feet dry and
well-ventilated, and continue Funginix for the full 3-month course
even after visible improvement. People with diabetes or poor
circulation are at higher risk for recurrence and should take extra
preventive care.

The most reliable sign of improvement is clear, healthy nail growing in at the base (near the cuticle). Because nails grow slowly — roughly 1.5mm per month for toenails — this process takes time.The existing discolored, thickened nail will still be present and must grow out naturally. Do not stop treatment when you see early improvement; continue through the full course for lasting results.
