One of the most frustrating things in life is when you take the time and effort to very carefully paint your nails, making sure the nail polish is perfect, only to accidentally smudge it before it fully dries. A smeared layer of nail polish is practically impossible to fix or cover up, so you feel like you wasted your time.
Before you consider your manicure done, help it dry faster by soaking your hand in a bowl of water. Yes, you read that correctly! If you soak your fingers in ice water, the cold can help the polish set faster, making your top layer harden faster to go about your day without worrying about smears.
