### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Ridge Filler
  

*by M***T on Reviewed in the United States on June 22, 2024*

I really like this stuff. It is matte and clear as if you did not even have on any polish.  It will stay on by itself for two or three days. It will stay on longer than that if you continue to add coats of polish to the top.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Helps to retain polish. Not very effective as ridge filler.
  

*by T***Y on Reviewed in the United States on June 28, 2024*

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    It works!
  

*by A***R on Reviewed in the United States on April 14, 2024*

I have been using this for 6 months and my nails are much improved and i am very happy with the results. My issue is that the bottles i had before (used as base coat and top coat) leeft a clear shiny finish. The bottle i just got is a satin finish and not quite clear. I didn’t see where there was a note that they were changing the finish!I want the clear shiny finish!!  How do I get that again??
