If you are going to thin gel nail polish, use gel nail polish thinner. Gel nail polish has a special UV reactive makeup, so using regular nail polish thinner may prevent it from working properly.
Do not use acetone or nail polish remover to thin gel nail polish.
Acetone may ruin the nail polish. It might be a good idea to do this when the bottle is almost empty.
Sometimes, you may need to leave the bottle open for a few days. This will depend on how hot, cold, dry, or humid the room is.
Use caution if storing it in the refrigerator door. The cold climate may help the polish last longer, but it is also a closed-in space. If the polish breaks in the fridge, you may have a potential fire hazard due to the fumes. [9] X Research source
