This stuff is magic. I started using it after I did the First Aid Kiss treatment. My nails were a mess from gels. I love the shiny quality to it so sometimes I would leave it on without putting a color over it. But now I use it as my go-to base coat. My nails are so much stronger and healthier. And I don't know if it helps but my polish lasts forever!

This is an amazing 2 in 1 foundation. I saw results within the first week.

I've almost completed my first 2 week round of using Firm Foundation, and I'm so pleased! It is actually working on my weak nails and strengthening them.

My nails damaged from too many months of gel & acrylic touch ups by a professional manicurist. I wanted to get back to a more natural nail. Am an artists, my hands are constantly being abused. They are still too damaged to go bare, this undercoat base coat really helps.

I'm sorry to say that I didn't like this. After putting it in my nail I just didn't feel right. Not that I have the best nails to begin with.

I found this polish treatment at my local pharmacy 2 years ago and it saved my nails! I used to bite my nails when I was younger and they have been really weak after getting gel nails at the salon for over a year. I use it as a base to keep them shiny. I also layer it with my favorite polish and it lasts 3 weeks no chipping! I tell all my friends about this polish often!

This is a product that really helps. Some of my nails were peeling and using the Firm Foundation as a base coat has helped tremendously. Also, when used as a base coat it really makes my manicure last. I will definitely order again.

My nails are not hard so they always chip and split. This nail hardener works great. It strengthens my nails so I can polish them.

I am hoping this will stop my nails from breaking, pealing, and splitting.

I like this better than All About That Base and it has lasted a long time. I think it goes on smooth and thin, and it keeps the polish on better.

Does not peel and crack like others. And after a few days, I'm able to apply another coat right over the old coat and it loks fine.
