I honestly figured it would take several applications of this to get the polish off, but it didn't! I soaked a cotton ball in the solution, put it to my nail and rubbed it back and forth. I only needed one cotton ball per hand, despite two layers of polish and one layer of strengthener on each nail. I also love that it doesn't have such a chemically smell as other polish removers do.
Now, I need to mention that I only used this on my natural nails. If you are looking for a review of removing the polish off of fake nails, I really don't know. I do know that it made my natural nails feel clean and smooth. I'm really happy with this product and feel good that I can use it on my daughter's nails because it is chemical-free!
