I was about to toss three bottles of gel polish that had turned into glue, and a few drops of this brought them right back to a workable consistency. It mixes in fine with both my UV and LED formulas, no weird separation after. Saved me from rebuying colors I actually liked.
The dropper makes it so easy to add just a few drops at a time, no mess or guesswork. I used it on a UV gel that had gone thick and stringy, and after a good stir it brushed on smooth again. Saved me from repurchasing three bottles.
I almost tossed a goopy bottle of my favorite red, but three drops of this thinner brought it back to its original consistency. The dropper makes it mess-free, and it works perfectly with my LED-cured polishes.
