The Tetra Corporation Formula 3 Antifungal Review

Manufacturer’s Claim

This is a comprehensive review of Formula 3 Antifungal to provide you with facts you need to know about this product. It claims to be the preferred effective antifungal treatment. It can help treat any fungal aliment such as ringworm, nail fungus, and athlete’s foot. Find out more about how Formula 3 Antifungal works and if it is an effective solution for your fungal problems.


After studying the manufacturer’s website and the label of the product, we were unable to find proper evidence of the ingredients used in this product. We did however come across a few statements where it was mentioned that the product contains tolnaftate and jojoba oil.

For effective treatment, the product should contain clinically proven 25% undecylenic acid with an added essential oil blend of tea tree oil and manuka. This will help eliminate the fungus, provide soothing relief, heal the affected area, and prevent it from recurring.


First the user must clean the affected area and dry it properly with an absorbent towel. Then, apply a thin layer of the product across the affected area. This should be done twice a day. Preferably once in the morning and once in the evening. This will allow the product to penetrate the tissue and reach the fungal growth area. Do not skip applications. Remember to apply it regularly. It is also important to change shoes and socks at least twice a day. Keep feet dry.


Unfortunately, there is no price given for Formula 3 Antifungal. Without a price, the customer cannot make an informative decision whether to purchase this product or another product. However, you are more likely to choose a product that has a price. The absence of this information may hinder purchases from customers.

Possible Side Effects

The product contains tolnaftate, which may be harmful to women who are pregnant or lactating. Furthermore, the natural oils in this product do not contain essential oils, so the risk for an allergic reaction is very rare. Persons with hypersensitive skin may experience redness or irritation. Consult a doctor before the use of this product and stop use if any problems occur.


The manufacturer does not offer a money-back guarantee on online purchases. Products may only be returned if purchased at the office of a licensed medical practitioner. This means that first time users will not be able to test the product and return it for a full refund if it does not work. Lack of a guarantee for online purchases may indicate that the product is not effective and that the manufacturer is not confident in the product. You are better off using a product that is backed by a strong guarantee.

The Tetra Corporation Formula 3 Antifungal Review – The Bottom Line

There are a few things that we like about Formula 3 Antifungal. The manufacturer provides the user with clear instructions on when and how the product must be applied.

However, there are many more things about this product that we do not like. Firstly, it does not contain 25% undecylenic acid or any essential oils such as tea tree oil or manuka oil. Lack of these important ingredients may leave the product ineffective in comparison with other products that do contain it. The manufacturer does not show the price of the product on the official website. Lastly, the manufacturer does not offer a money-back guarantee on products that have been purchased online. This is why we cannot recommend the use of Formula 3 Antifungal.
