Gel Nail Polish is naturally a little thicker than regular polish, particularly glitter polish.To make your polish easier to manage, you can try turning the closed bottle upside down and rolling it between your hands, rather than shaking. The heat from your hands will help to warm and thin out the polish. When applying your Gel Nail Polish, you can also try wiping the brush against the neck of the bottle to remove excess polish. If this doesn't help, you can try running your closed gel polish bottle under hot water to heat up the polish. After a minute or two under the hot water, roll the bottle between your hands. Be careful because the bottle can get very hot. Repeat this process until your polish is a good consistency. Additionally, please ensure you are following our storage instructions outlined on the product page.
