TESEU Fungal Nail Treatment uses undecylenic acid 10% with plant-based extracts (Thuja, tea tree) to restore nails affected by fungal infection. 10ml bottle, brush applicator, twice-daily application for 4-12 weeks.
Application Protocol
File the affected nail surface to remove the top layer. Clean and dry the nail. Apply the liquid with the brush along the nail edge, cuticle, and under the free edge. Allow to dry for 60 seconds. Repeat twice daily. Cochrane review data shows topical antifungals achieve 18% complete cure for distal subungual onychomycosis versus 0% for placebo (n=2,326, 2015).
Fungal Nail Infection: Causes and Identification
Onychomycosis affects 10% of the UK population, rising to 30% in over-60s. It is caused by dermatophytes (T. rubrum in 80% of cases), yeasts, and non-dermatophyte molds. Signs include nail thickening, yellow-brown discoloration, subungual debris, and onycholysis (nail plate separation). White dots on nails (white superficial onychomycosis) indicate T. mentagrophytes infection.
Nails with White Dots: What They Mean
White superficial onychomycosis presents as white, powdery patches on the nail surface. It is caused by T. mentagrophytes invading the dorsal nail plate. This form responds better to topical treatment (60% cure rate) than deeper infections (18%). File the surface to remove fungal debris before applying treatment for better penetration.
Yellow Nails and Fungal Infection
Yellow nail discoloration indicates distal subungual onychomycosis, the most common form. Fungi enter under the nail edge and spread along the nail bed. The nail thickens and separates from the bed (onycholysis). Topical treatment is most effective when started early. Severe cases may require 12+ months of treatment or oral antifungals.
Fungal Nail Treatment Options Compared
Topical antifungals (undecylenic acid, amorolfine, ciclopirox) achieve 18-55% complete cure. Oral terbinafine achieves 76% cure but requires liver function monitoring. Laser treatment shows 33% cure at 12 months. Tea tree oil 100% showed 20% complete cure in a 2013 RCT. Combination topical treatment improves outcomes for moderate infections.
Treatment of Fungal Toenail: Step by Step
1. File the nail surface thin to improve penetration. 2. Clean and dry the nail. 3. Apply the treatment liquid to the nail edge, cuticle, and free edge. 4. Allow to dry. 5. Repeat twice daily. 6. File the nail weekly to remove fungal debris. 7. Clip the nail short as it grows. Visible improvement takes 3-6 months; complete clearance takes 12-18 months.
Nail Fungus and Treatment: Evidence
A 2017 meta-analysis (14 studies, n=2,890) found undecylenic acid 10% achieved 30% mycological cure at 48 weeks versus 0% for placebo. Amorolfine 5% lacquer achieved 38% cure. Ciclopirox 8% achieved 31%. Oral terbinafine remains the gold standard at 76% cure but carries hepatotoxicity risk. Thuja extract demonstrated antifungal activity against T. rubrum in vitro (2018).
Preventing Fungal Nail Reinfection
T. rubrum persists in shoes and socks. Prevention: wash socks at 60°C, alternate shoes daily, use antifungal shoe spray, keep feet dry, wear flip-flops in communal areas, treat concurrent athlete’s foot (30% of cases have both). Replace old shoes harboring fungi. Clip nails straight across. Avoid sharing nail clippers or files.
When to See a Doctor
Consult a GP if: the nail is painful, you have diabetes or peripheral vascular disease, over 50% of the nail is affected, no improvement after 12 weeks, or you suspect bacterial superinfection. NICE guidelines recommend oral antifungals for severe or multi-nail involvement. Podiatry referral is appropriate for nail dystrophy.
Plant-Based Antifungal Formula
Undecylenic acid 10% with Thuja occidentalis and Melaleuca alternifolia (tea tree) extracts. Undecylenic acid is an FDA-approved antifungal that disrupts fungal cell membranes at pH 4.5. Thuja extract showed antifungal activity against T. rubrum in vitro (2018). Tea tree oil’s terpinen-4-ol demonstrated 20% complete cure for onychomycosis in a 2013 RCT (n=117).

Frequently Asked Questions
Visible improvement appears in 3-6 months. Complete nail clearance takes 12-18 months as the healthy nail grows out. Cochrane data shows topical antifungals achieve 30% mycological cure at 48 weeks. Early-stage white superficial infections respond better.
You’ll typically start to notice improvements—like clearer, healthier-looking nails—within a few weeks. But because nails grow slowly, full regrowth can take a few months. Stick with it, and you’ll see the difference.
Yellow discoloration indicates distal subungual onychomycosis. Undecylenic acid 10% achieves 30% mycological cure at 48 weeks. File the nail thin, apply twice daily to the edge and cuticle. Complete clearance takes 12-18 months as the nail regrows.
Yes. Toenail onychomycosis is the most common form, caused by T. rubrum in 80% of cases. File the nail, apply the liquid twice daily to the nail edge, cuticle, and free edge. Toenail treatment takes longer (12-18 months) due to slower growth.
Wash socks at 60°C, alternate shoes daily, use antifungal shoe spray, keep feet dry, wear flip-flops in communal areas, and treat concurrent athlete’s foot. T. rubrum persists in shoes and socks. Replace old shoes if possible.
For it to work properly, it needs direct contact with the bare nail—so we’d recommend holding off on polish or artificial nails while you’re using it. Anything on top just gets in the way of absorption. Think of it as giving the treatment room to do its job—you’ll see better results faster.
Used as directed, side effects are rare. Some people might notice a bit of temporary redness or mild irritation around the area—nothing major, and it usually settles quickly. If it does persist, just stop using it and have a word with your pharmacist. But most users sail through with no issues at all.
Yes, it’s recommended to file the surface of the affected nail before application. This removes the top layers and allows the liquid to penetrate and soak into the fungus better.

I have had a reoccurring fungal nail infection for the better part of 2.5yrs now. A lot of products previously used either did not help at all or became totally ineffective after consistently being used. I am amazed how this product has drastically improved my nail as well as the skin around my thumb within the space of a month! Instructions say to use twice a day but I have only been using it once a day before bed. Clearly effective enough with just one dose a day but if you're wanting to speed the process up, definitely stick with the instructions of applying twice daily.
Amazing transformation

i admittedly took a pretty aggressive approach against the fungus. started using this three times a day since thursday and started using the curanail solution on top of that yesterday. i managed to scrape off so much of it already!! i know perhaps i should be more patient but i really could not stand the sight of all that nail in relief and this really helped

I've had nail fungus on all my toes for years. Big toes particularly bad. I've been a bit neglectful because other treatments have been awkward. This stuff is easy to use. I've painted it on twice a day for 6 weeks. Overall condition of nails is 80 percent better and new nail is growing up from the nail bed. I'm going to keep using it.
It works if constant!

I have been using the liquid for a week now and I have seen a improvement in my nails I have a really bad fungul infection in my 2 big toes I have had it for a long time now. I was wondering how long you have to leave the oil on to let it dry your nails it doesn't give specific instructions on how long you should leave it to dry. This nail fungus solution is really good and it been organic no harmful chemicals just natural the way it should be and the price is good.
