What is actually in DermaFix Nail Fungus Treatment Gel, and why? This page examines each ingredient individually — what the research says, its specific role in the formula, and any limitations worth knowing.
DermaFix does not rely on a single active ingredient — it uses a layered formulation with each component serving a specific role. The ingredients fall into three functional groups:
This layered approach is more sophisticated than products that include one or two antifungal ingredients in a basic carrier. Understanding each component helps you evaluate whether this formula suits your specific situation.
Transparency note: DermaFix lists its key ingredients but does not publicly disclose precise concentrations for individual actives. This is common practice for cosmetic topicals but is worth noting for those who want to compare specific ingredient levels against clinical research benchmarks.
Tea tree oil is extracted from the leaves of the Melaleuca alternifolia plant, native to Australia. It has one of the strongest research profiles of any naturally-derived antifungal agent for topical use.
What the research says: Multiple peer-reviewed studies have demonstrated tea tree oil's in-vitro activity against Trichophyton rubrum, T. mentagrophytes, and Candida species — the organisms most commonly responsible for nail fungus. A 2002 study published in the Journal of Family Practice found that 100% tea tree oil was as effective as 1% clotrimazole solution in improving nail appearance and symptom scores after six months. A 2013 study found synergistic antifungal activity when tea tree oil was combined with other natural antifungals.
Mechanism: Tea tree oil disrupts fungal cell membrane integrity, leading to cell content leakage and fungal cell death. The primary active component is terpinen-4-ol, which accounts for most of its antimicrobial activity.
Role in DermaFix: Primary natural antifungal agent. Its effectiveness in the formula depends heavily on the delivery system ensuring it reaches the nail bed — which is where the Emu Oil carrier system becomes critical.
Concentration note: Clinical studies on topical tea tree oil for nail fungus have used concentrations ranging from 25% to 100%. DermaFix does not disclose its concentration. Effectiveness at lower concentrations depends on the delivery mechanism rather than concentration alone.
Colloidal silver consists of silver nanoparticles suspended in a liquid base. It has been used in antimicrobial applications for over a century and has seen renewed interest in cosmetic and topical wellness formulations.
What the research says: Laboratory studies have shown silver nanoparticles to have broad-spectrum antimicrobial activity, including against various fungal species. Research published in the International Journal of Nanomedicine (2017) demonstrated antifungal activity of silver nanoparticles against Candida and certain dermatophyte species. The mechanisms appear to include disruption of cell membranes and interference with cellular respiration.
Role in DermaFix: Provides complementary antimicrobial support alongside Tea Tree Oil. The combination may offer broader coverage and potentially some synergistic activity against the fungal organisms present in nail infections.
Bacillus Ferment is a biotechnology-derived ingredient produced through the controlled fermentation of Bacillus bacterial cultures. It is used in advanced skincare formulations for its enzymatic activity.
What the research says: Research on ferment-derived ingredients in cosmetics suggests roles in supporting the skin microbiome, gentle enzymatic exfoliation of damaged surface cells, and improving skin texture. Bacillus-derived compounds have demonstrated some antimicrobial properties in laboratory settings.
Role in DermaFix: Supports the skin's natural microbial environment and assists with gentle removal of compromised surface nail tissue. This exfoliating action may help improve absorption of the active antifungal ingredients by reducing the barrier of damaged keratin on the nail surface.
Emu oil is rendered from the fat of the emu bird (Dromaius novaehollandiae) and has been used in traditional Australian medicine and, more recently, in evidence-informed cosmetic formulations. It is arguably the most scientifically significant ingredient in DermaFix.
What the research says: Emu oil's transdermal penetration properties have been documented in multiple published studies. Research by Dr. Michael Hollick at Boston University demonstrated emu oil's ability to penetrate multiple layers of skin, stimulate skin cell proliferation, and reduce inflammation. A key property is its high oleic acid content and its unique fatty acid composition that closely matches the lipid barrier of human skin, allowing it to penetrate where many other oils cannot.
Mechanism: Emu oil works as a transdermal carrier — it physically transports other lipid-compatible molecules (including terpinen-4-ol from tea tree oil) through the skin and nail layers to reach the subungual space where the fungus resides.
Role in DermaFix: This is the delivery engine of the entire formula. Without an effective penetrating carrier, the antifungal agents stay on the nail surface. Emu Oil is what makes the Deep Absorption Technology claim substantive rather than just marketing language.
Squalane is a hydrogenated, stable form of squalene — a lipid that is naturally produced by human sebaceous glands and makes up approximately 12% of human sebum. In cosmetics, squalane is most often derived from sugarcane or olive oil through a hydrogenation process.
What the research says: Squalane is one of the most well-researched cosmetic emollients. Its molecular structure is similar to human skin lipids, giving it excellent skin compatibility and absorption characteristics. It has been shown to improve skin barrier function, reduce transepidermal water loss, and enhance the penetration of co-formulated ingredients.
Role in DermaFix: Serves a dual function — as a secondary penetration enhancer working alongside Emu Oil, and as a conditioning agent that keeps the nail bed and surrounding skin hydrated throughout the treatment period.
Vitamin E is a fat-soluble antioxidant vitamin that has been widely used in topical formulations for decades. It exists in eight natural forms; tocopherol (particularly alpha-tocopherol) is the most biologically active.
What the research says: Topically applied Vitamin E acts as a free radical scavenger, protecting skin and nail cells from oxidative stress. Research supports its role in improving skin hydration, reducing the appearance of nail brittleness, and supporting tissue repair processes.
Role in DermaFix: Provides antioxidant protection to the recovering nail bed tissue. Chronic nail fungus creates localised oxidative stress; Vitamin E helps counteract this while also supporting the health of new nail growth.
Cold-pressed olive oil is a classic cosmetic ingredient with a long history of use in skin and nail care. It is rich in oleic acid, squalene precursors, and polyphenolic antioxidants.
What the research says: Olive oil's emollient and skin-conditioning properties are well established. Its oleic acid content penetrates the skin barrier and supports moisture retention. Some research also suggests mild antifungal properties, though these are significantly weaker than the primary antifungal agents in the formula.
Role in DermaFix: Conditioning agent for the nail bed and perungual skin. Provides fatty acid nourishment to skin tissue recovering from the damage caused by chronic fungal infection.

All these ingredients work together in DermaFix's once-daily application system.
Each ingredient in DermaFix has evidence for its individual function. But the formula is more than the sum of its parts. The Emu Oil and Squalane create a delivery vehicle specifically suited to transporting lipid-compatible active ingredients (like the terpinen-4-ol in Tea Tree Oil) beneath the nail plate — something that would not occur if tea tree oil were simply applied in a water-based or alcohol formula.
The combination of Bacillus Ferment's exfoliating action, Emu Oil's penetration, and the dual antimicrobial action of Tea Tree Oil and Colloidal Silver creates a formula that addresses the nail fungus problem from multiple angles simultaneously.
As noted above, precise concentrations are not publicly disclosed. For consumers who want to compare DermaFix's Tea Tree Oil level against the 25%–100% range used in clinical studies, this information gap is a real limitation. The formula's effectiveness at lower concentrations would depend entirely on the penetration efficiency of the delivery system — which may compensate substantially, but cannot be independently verified without concentration data.
This is not an unusual position for cosmetic topicals, but it is worth noting for any informed purchase decision.
