How is this stuff not at the top of nail aficionados "Must Have" lists?? I had never tried a product like this before as I (mistakenly) thought a light lick or dab of remover would do the trick. I was so wrong!! You can use this on wet or fully dry polish. I've used multiple times on dinged up wet/damp polish (make sure you brush over the entire nail and not just the smudge as it smoothes and evens everything out), but recently found myself with the dreaded sheet imprints on every nail.
The photos show the pinky nail smoothed out with the other 4 a mess. Next photo is 2nd finger fully and 1st finger halfway, so you can see the transition. Last photo is fully smudge free and good as new!! I will never be without this in my nail kit!
*Note: I did not have a top coat on yet and applied after I used the Smudge Fix. I assume it would work just as well on top-coated nails but you may need to apply an additional top coat to re-seal everything.
