DISCLAIMER

Please read this page in full. By continuing to browse our website or by purchasing our products, you confirm that you have read, understood and accepted everything below.

1. WHAT THIS PRODUCT IS

KillFungus LABS nail polish is a cosmetic product. It is a colored nail lacquer, formulated with cosmetic ingredients and manufactured in a facility certified GMP and ISO 22716.

It is not a drug. Cosmetic products are not approved by the U.S. Food and Drug Administration. This product has never been submitted to, approved by, or evaluated by the FDA.

These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease or medical condition, including onychomycosis or any fungal infection.

2. ABOUT OUR BRAND NAME AND PRODUCT NAME

Our brand name and the name of our product refer to the ingredients contained in the formula and to the audience we serve. They describe ingredients that are recognized in cosmetic use, and the concern our customers are dealing with.

They are not a claim that this product treats, cures, eliminates or prevents any infection or disease. No wording used anywhere on our website, our packaging or our advertising should be understood as such a claim.

3. WHAT THIS PRODUCT IS NOT

We want you to buy with a clear understanding of what you are buying.

It is not a medical treatment for nail fungus. In the United States, no over-the-counter product is approved to treat fungal infections of the nail. All approved nail fungus treatments are available by prescription only.
It is not a substitute for seeing a doctor or a podiatrist.
It has not been the subject of a clinical study. Any description of ingredients or of how they work refers to published research on those ingredients in general, not to testing carried out on our finished product.
It does not contain drug-level concentrations of any active ingredient. Our formula contains cosmetic levels of undecylenic acid, tea tree oil and vitamin E. For reference, the FDA over-the-counter monograph for undecylenic acid as an antifungal drug specifies a concentration of 10% to 25%, applies to skin conditions only and not to nails. Our product is a cosmetic and is dosed far below that range.

4. WHAT IT CAN AND CANNOT DO FOR YOU

What it does. It covers, colors and improves the appearance of nails that are discolored, thickened or damaged, from the first application. It contains conditioning and botanical ingredients intended to care for the appearance of the nail while it grows out.

What it cannot do.

It cannot make a damaged nail become healthy instantly. A toenail takes approximately 6 to 12 months to grow out completely, a fingernail 1 to 4 months. Nothing applied to a nail can accelerate this biological process.
It cannot guarantee that a fungal infection will disappear. Even prescription treatments prescribed by physicians achieve complete cure in only a minority of cases.
It does not allow other topical treatments to be applied over it. If you use a medicated nail lacquer, cream, serum or any topical treatment, you must remove our polish first so that your treatment can reach the nail. Applying a treatment on top of our polish will not work.
It does not allow foot soaks to reach the nail. Our polish forms a water-resistant film. Vinegar, baking soda, salt or any soak will not penetrate it. To benefit from a foot soak, remove the polish first.
Like any nail polish, it covers the nail. A covered nail is less exposed to air and light than a bare nail. If your only objective is to fight a fungal infection by medical means, a bare, dry, aired nail is preferable. Our product is designed for people who want a presentable nail while they manage their condition, not as a replacement for medical care.

5. IT DOES NOT PROTECT YOU FROM INFECTION OR SPREAD

Do not rely on this product as a protective barrier.

It is not intended to prevent a fungal infection, and it must not be used for that purpose.
It does not prevent an existing infection from spreading to your other nails, to your skin, or to other people.
Wearing it does not make it safe to walk barefoot in swimming pools, showers, locker rooms, gyms or any shared space.
It does not replace the hygiene measures normally recommended for fungal conditions.

6. DO NOT REPLACE A MEDICAL TREATMENT WITH THIS PRODUCT

This is the most important warning on this page.

If a physician, podiatrist, dermatologist or pharmacist has prescribed or recommended a treatment for your nails, continue it. Do not stop, interrupt, reduce or delay a prescribed treatment in order to use our product, and do not use our product instead of seeking medical care.

Our product is a cosmetic. It is intended to be used alongside proper medical care, never in place of it.

If you are unsure whether our product is compatible with your treatment, ask your healthcare provider before using it.

7. GET A DIAGNOSIS BEFORE ASSUMING IT IS FUNGUS

Nail discoloration, thickening, crumbling, lifting or deformation can have many causes other than fungus, including trauma, psoriasis, eczema, lichen planus, bacterial infection and, in rare cases, melanoma.

A dark, black or rapidly changing nail should always be examined by a physician without delay.

We strongly recommend obtaining a diagnosis from a qualified health professional before assuming that your condition is fungal.

8. CHECK YOUR NAIL REGULARLY

Because our product covers the nail, it also hides it.

A colored polish will conceal the natural appearance of your nail, including any change in that appearance. You must therefore remove the polish regularly to inspect your bare nail, so that you can notice any worsening, any new symptom, or any sign that requires medical attention.

Do not allow a cosmetic product to prevent you from monitoring your own health.

9. WHO SHOULD NOT USE THIS PRODUCT WITHOUT MEDICAL ADVICE

Do not use without consulting your physician first if you:

have diabetes, peripheral neuropathy, poor circulation or any vascular condition affecting your feet
have a weakened or compromised immune system
are pregnant or nursing
intend to use the product on a child
have a nail that is painful, bleeding, oozing, or where the surrounding skin is red, swollen or infected
are undergoing chemotherapy or any treatment affecting your nails or skin
have a known allergy or sensitivity to essential oils, in particular tea tree oil

If you have diabetes, please take this seriously. Foot conditions in diabetic patients can progress rapidly and require medical supervision.

This product is intended for adults. Purchases should be made by persons aged 18 or over.

Do not apply over artificial nails, gel, acrylic, or any other nail product, and do not apply to a nail that is lifting or detached from the nail bed.

10. ALLERGY AND SENSITIVITY

This product contains essential oils, including tea tree oil (Melaleuca alternifolia), which is a recognized contact allergen for some individuals.

Before first use, perform a patch test. Apply a small amount to a limited area of skin, wait 24 hours, and check for any reaction.

Read the full ingredient list on the bottle before use, particularly if you have known allergies.

11. SAFE USE AND HANDLING

For external use on nails only. Do not apply to broken skin or open wounds.
Do not ingest. If swallowed, seek medical advice immediately.
Avoid contact with the eyes. If contact occurs, rinse thoroughly with water.
Flammable liquid. Keep away from heat, sparks, open flame and hot surfaces. Do not smoke while using. Store in a cool, dry place, tightly closed.
Keep out of reach of children.
Use in a well-ventilated area.
Do not share your bottle or your nail tools with other people. Fungal nail conditions can be transmitted.
If the product changes in color, texture or odor, stop using it.

12. REMOVAL

Our polish is removed with a standard nail polish remover, which is a separate product with its own instructions and precautions. Read and follow the instructions of the remover you use.

Removers can dry out the nail and the surrounding skin. Frequent application and removal may affect the condition of the nail plate. Allow your nails periods without polish.

13. STOP USING THE PRODUCT IMMEDIATELY IF

you experience irritation, redness, swelling, itching, burning, blistering, pain or any discomfort
the skin around the nail becomes inflamed, warm or painful
your nail becomes painful, bleeds or starts to separate from the nail bed
your condition worsens in any way
you develop any symptom you did not have before using the product

In any of these cases, stop use and consult a healthcare professional.

Similarly, if you see no improvement at all after several months of consistent use, stop relying on a cosmetic solution and consult a physician or podiatrist.

14. RESULTS AND EXPECTATIONS

Individual results vary, and no specific outcome is guaranteed.

Results depend on many factors outside our control, including the severity, duration and underlying cause of your condition, your nail growth rate, your age, your general health, your circulation, your footwear and hygiene habits, and how consistently you use the product.

Nails grow slowly. Any change in the appearance of the nail itself takes months. The immediate benefit of our product is cosmetic coverage, not biological change.

Some people will see no improvement at all in their underlying condition.

15. TESTIMONIALS, IMAGES AND REVIEWS
