Tea tree oil's antifungal properties are real lab science — but DermaFix doesn't publish where its concentration falls, and one other ingredient has its own FDA history worth knowing.
DermaFix names its full ingredient list on the label — tea tree oil, colloidal silver, emu oil, squalane, vitamin E, bacillus ferment, and olive oil. That's real transparency most topical products in this category skip entirely.
What isn't disclosed is the concentration of any of these actives. We cover the broader research landscape in our full nail fungus treatment guide — the short version here is that clinical studies on topical tea tree oil for nail fungus generally tested concentrations between 5% and 25%. Without knowing where DermaFix's formula falls in that range, independent efficacy assessment simply isn't possible.
Worth knowing before you buy: One named ingredient, colloidal silver, has its own FDA history — the agency has stated colloidal silver products are not generally recognized as safe and effective, and has taken action against companies for misleading claims. The more serious safety concerns are mainly linked to oral or internal use rather than topical application, but it's worth reading before this ingredient factors into your decision.
A genuinely transparent ingredient list with a real delivery mechanism (emu oil and squalane as carrier oils) — better disclosure than many competitors. The real limitations are the missing dose data and the colloidal silver history, both worth weighing honestly rather than glossing over.

Tea tree oil, colloidal silver, emu oil, squalane, vitamin E, bacillus ferment, and olive oil — all named on the label. The concentration of each active ingredient isn't published.
Yes, in a specific way. Clinical research on topical tea tree oil for nail fungus generally tested concentrations between 5% and 25%. Without knowing where DermaFix's formula falls, it isn't possible to independently assess whether the dose is adequate.
The FDA has stated colloidal silver products are not generally recognized as safe and effective, and has acted against companies for misleading claims. The more serious safety concerns are mainly linked to oral or internal use rather than topical application, but it's worth understanding this history before the ingredient factors into your decision.
