Xenna’s new NonyX nail gel is designed to clear discoloring keratin debris from under nails. When applied to dark or yellowed nails the clarifying nail gel breaks down and removes discolored build up. With regular use the gel helps keep nails clear. NonyX nail gel is available in the foot care section of most chain drugs stores and mass retailers and in some independently-owned pharmacies. A retail store locator is available on the company’s website. Xenna’s preservative-free topical products are appropriate for the general population and for those with diabetes.
