Over time, polish can get thick and stringy. This is due to the evaporation of Butyl Acetate and Ethyl Acetate, two of the main ingredients in nail polish, the same ingredients that let the polish dry on your nails!
To restore thick polish, use Restoration Drops, our KBShimmer polish thinner. For slightly thickened polish, start with 2-3 drops, shake, and check consistency. Repeat until you are happy with the thickness of the polish. For dried out, or severely thickened polish, we suggest filling with thinner to the fill line (before evaporation taking into account any prior use). Let sit overnight, and shake in the morning. You may need to use a toothpick or paperclip to stir, allowing the thinner to reach the bottom of the bottle. As always, we highly suggest cleaning of the necks of the polish bottles after use to allow a good seal. This will reduce polish evaporation in the long run.
To prevent evaporation of thinner, store with regular top.
Please note, glitter polish is thicker than cream polishes generally. The use of too much thinner can reduce the suspension properties of glitter polishes, always start with 2-3 drops and only use what is needed to restore to original consistency.
