With a little prep, it works [SEP] First, you have to remove the top layer of gel polish with a nail file,  then apply to the nail only.  It's thick so it stays on.  Let it sit for sit for at least 10 full minutes. The polish will start to crack, then you can peel or scrape it off. You may need to reapply to the areas of stubborn polish that won't budge.  Try not to apply to skin or bare nail directly. If working on yourself,  do one hand at a time, so you don't get it on your skin.<br />I like to use it to get rid of most of the polish before going back to the salon.<br />It doesn't work perfectly,  but I prefer it to soaking my hands in acetone.
