What is keratin debris?

Keratin debris appears as a white, yellow or brown build-up or discoloration in your toenail or fingernail. Keratin debris is where nail fungus lives in your nail.  It is also the food supply of nail fungus.

How long will it take to get out the keratin debris?

Expect to see good results within 5 to 9 months as your nail grows out. Based on a clinical study, smaller nails may be clear in as little as three months.  You may be able to start scraping out any softened keratin debris in 3 to 6 weeks.  For fastest results apply Nonyx Gel twice a day, morning and night, especially after bathing. (Keep in mind that it takes about 21 days to make a new habit.) 

How long do you have to wait before you put on socks after you apply the product? Won't the socks absorb the gel and basically significantly reduce the effectiveness of each application?

Surprisingly, you do not have to wait for NonyX Nail Gel to dry before putting on your socks. There will be enough gel left on your nail  - despite some smearing off  - to continue the process of removing the keratin debris on and in your nail. Also the gel on your sock over your nails will support this process throughout the day.

Can I use NonyX on my child's nails?

You can use NonyX on your child if they are old enough (5 or older) to understand not to put their toenails or fingernails near their eyes or get the gel in their eyes, as NonyX is an eye irritant. You should apply the gel yourself and keep it out of reach of your child when not in use.

What is ethanoic acid?

The ethanoic acid in NonyX is the exfoliant of keratin debris. Ehtanoic acid used in NonyX breaks down only the keratin debris. It has no effect on your normal nail plate. The ethanoic acid in NonyX Nail Gel is made from fermented corn and wheat with water added.

Can nail polish be used while using NonyX?

If you wear nail polish, you can purchase NonyX BASECOAT, which is formulated to work under nail polish.

Does NONYX Nail Gel expire? 

Nonyx is best when used within 2.5 years after manufacture.  The manufacturing date is coded with an inked number on the underside of the bottle.  The year of manufacture is the first two numbers, e.g., 15, 16 or 17.  The day of manufacture are the next three numbers as the sequential day of the year.  Continuing to use NONYX after 2.5 years is not harmful, but less efficient.
