Approved Science Fungix Extra Strength - Undecylenic Acid and Tea Tree Oil - Serum for Fingernail and Toenail Care - Infused with Essential Oils - Healthy Nail Appearance - Easy to Apply - Pack of 1

This works! I have allergies to oral antifungals and was not able to treat the toe nail fungus I had for years. It was also affecting the skin between my toes. Antifungals from the drug store didn't work so, I decided to give Fungix a try two years ago. It first healed the skin between my toes within a few weeks. It has taken a long time for it to get rid of the fungus under my nails, but I kept using it because I saw improvement little by little. It is finally nearly totally gone under the nails and has never come back between my toes. The instruction say to use it multiple times per day and may have healed faster if I had done it like that, but it was a big inconvenience. I put it on once daily before putting on socks. I hate this because I didn't think I would ever get rid of this infection and hope this can help someone else.

With regular use it worked great to clear up serious toenail fungus. Now I use it to prevent recurrence. My toes are thankful!

The Nail Revival treatment is a seriously impressive product designed to support and condition both fingernails and toenails. It’s clearly formulated with quality and efficacy in mind, earning a strong four stars for its potent ingredients and commitment to clean crafting. The star of the show is the Undecylenic Advantage—featuring a full 25% Undecylenic Acid. This high concentration feels professional-grade and is what truly makes this formula stand out for focused nail health. It feels strong and protective without being harsh on the skin around the nail bed. Beyond the active ingredient, this formula shines as a true Hydration Station. The blend of Aloe Vera, Jojoba Oil, and Vitamin E ensures that while the acid is at work, your nails and cuticles are simultaneously getting deep moisture care. The combination prevents the dryness that often comes with focused nail treatments, which is a major win. The Blend of Botanicals is where the quality is evident, including rich essential oils like Lavender, Lemongrass, and Manuka. Knowing that it’s Purely Crafted—vegan-friendly, GMO-free, and made in a cGMP facility in the USA—provides excellent peace of mind about what you’re putting on your body. The only reason I held back the fifth star is related to that same botanical blend: the scent is extremely strong. While I appreciate the natural essential oils, the combined fragrance is very intense and takes a while to dissipate, making it something I prefer to apply only right before bed. If the fragrance were slightly milder, this would be a perfect 5-star product. Nonetheless, for performance and quality, it's highly recommended.

Excellent product!! It works very well. Highly recommend...

I think patience,dedication and consistency may be the key factors for this to work.. I am on my 4th bottle and I faithfully apply this 4 times a day. Granted, I many have missed an application now and then but seldom. I am just now noticing some clearing on both of my big toes. The other toes were and are unaffected by the fungus. So this may not be a quick fix but toe nails grow slowly and Rome wasn't built in a day. I know some didn't care for the smell but TBH, I found it had a clean odor to it. Once I see nothing of the fungus, I'll change the number of stars in my rating.

Waste of money and seems to have discolored the nail. I suggest just go to the doctor and get the cheap script because this product is a waste of time and money.

UPDATE 10/2024: When I purchased initially, these Fungix bottles $27; significantly more expensive than other solutions. After nearly two years of using, my nail made only moderate progress with this treatment and so about six months ago, switched to another product, much less costly product, which appears to have been more effective. I went just now to buy a bottle of Fungix (using a multiple solution approach) and I was baffled to see this product has almost doubled in price - $47-$52 per bottle. So, while it seemed to stop the progress of the fungus it did not resolve it over two years of use. And since they have made the price ridiculously high, I would try other solutions. Actually - vinegar soaks have provided the very best results of anything I've tried. After 4 months . . . and one bottle - optimistic. I did not take before/after pictures because this product was the third or fourth product I had tried, and frankly my expectations were low. After noticing my first indications of a toenail fungus in February (the first in my life), my large toenail continued to deteriorate further back into the nail while using several other treatments purchased online. When I began using Fungix in June, I had lost about 1/2 of my toenail. I applied the product 3-4 times per day and always before going to bed. I filed the nail once per week after a shower when the nail was soft. In early September at my annual Dr. appt. the deterioration had reversed and it appeared that the base of the nail was regaining health. When I told the doctor my story, he asked for, and made a note of, the product I was using. He said whatever I was doing was working given the health of the base of the nail and to continue - it would take time. He said the oral meds he would give me had known risks to liver functions and would not work better than what he was seeing on my nail. At the end of bottle one I have seen a complete reversal of the fungus effects. Most of the deteriorated nail has now grown off of my toenail and there are no new areas of deterioration behind that original area. On one end of my toenail I am now clipping healthy nail when I trim my nails. The nail continues to be discolored and prone to irregular thickness at the remaining effected area. It is not 'beautiful' healthy nail, yet, and it may never look like the other nails around it. But it is much much improved. It has taken 4+ months of solid consistent application and lots of attention and it may be a perpetual battle. But that effort is much better than losing a nail to an active fungus. If you can tolerate tea tree oil and whatever is in this product (I actually found the scent enjoyable), it may work for you as well. It's a marathon though, so be patient.

I had very, very advanced problems on all ten toes. Really gross--take my word for it. I have now followed the regime religiously for almost 3 months and the improvement is nothing short of amazing. There was noticeable improvement in the first two weeks and it has just gotten better since then. I can now wear sandals without fear of scaring small children. I purchased two bottles and they were worth the cost. One caveat: This product will NOT fully cure the problem. It mitigates it wonderfully, but only the doctor-prescribed stuff is strong enough to kill the fungus. It will come back if you stop using the product without taking the medication step. Just FYI, not a knock against the product.
