I -think- that you're putting the acetone on too heavily after your layers. You need to brush it very lightly so as to only take off the top layer and let the under-color show through. This looks as though you took a dotting tool and dragged it through the polish down to the nail.
Thank you. Have done it before and it worked out well. Part of me thinks its the polish as its not a great formula xo
Not heard of an acid wash mani before, will go off and google it, love the pink Woo polish x
I couldn't get that polish to set for me at all =/ but we all get bad mani's now and then xo
