NONYX Fungal Nail Clarifying Gel, (pronounced Non-X), is a toenail fungus treatment that cleans out keratin debris where nail fungus thrives. Clinically proven effective, 90% of nails significantly improve by at least 80%, based on a 9-month study. NONYX works by targeting the food supply of nail fungus. This food is keratin debris. Once keratin debris is gone (and the nail fungus with it), fingernails and toenails look clear and healthy again. NONYX is an effective nail solution for damaged and discolored fingernails and toenails and improves the appearance of nails that are yellow, thick, dark, brittle, broken, cracked or lifting. Dermatologist tested, it is safe for diabetics with healthy feet and a choice of doctors for over ten years. NONYX is economical and convenient to use. One 4 oz. bottle is a six month supply. NONYX can also be used under nail polish! Made in the USA, NONYX is vegan, not tested on animals, contains no animal byproducts and is free of parabens and preservatives. NONYX is money-back guaranteed by the manufacturer XENNA Corporation – there is no time limit to this guarantee. NONYX is unique.
