My mistake?  This is not for powder nails.
It did remove a thin layer, so that's not a zero.  I'm very cautious not to get it on my skin, but the way this barely worked, I want to glob it on.  Then I will prob. get some on my skin.  I'll try again later when I have more time, and can sit at the table  ( I wasn't).  I'll edit this review if things improve on my next attempt.  /  Now I have just noticed the reviews talk about gel polish, and that is not what I have.  I have dip powder nails.  There is a clear gel topcoat, and that what it is removing.  My mistake.
