## Questions & Answers

**Q: Does this contain Formaldehyde? One user said you have to apply to tips only but Amazon directions say the whole nail?**
A: There are no ingredients listed on the bottle but what I do know is that it does exactly what it promises. Because of CoVid, I was unable to have my jails done. Once I removed the gel, my nails were very thin and weak. In the last 6-8 weeks since using this product, my nails look great! I use the polish on my entire nail..

**Q: This chips within a day of applying. Any tips to stop this? I used exactly as the bottle says to use....**
A: Yes it chips. And it works. It is very thin. Don’t think of it as a nail polish. Think of it almost as a serum, like you would put on your face. Keep putting it on. When it builds up, take it off and reapply. Eventually you will not have to have it on 24/7. This works where all the topical hardeners in the world did not. It’s cheap-use it every day.

**Q: Do you apply 2 coats every day for three days?**
A: Yes I apply a couple coats every day …sometimes even over polish …
Then remove it and start over …I often start with two or three coats the first day…..
The product has really helped my nails grow.

**Q: The ingredients list acetate in various forms and alcohol. Aren’t these ingredients bad for nails?**
A: While acetate and acetone sound similar they’re not actually the same thing and thus don’t have the same effect on nails, and adding alcohol to a word means that something is bonded with a Hydrogen-Oxygen group of atoms, not all alcohols have the same properties and so not all of them damage nail polish
