"Our chemists invented a modern solution to the normal polish inconveniences that frustrate women," says CND co-founder and style director Jan Arnold. "Shellac is fret-free and convenient. Women can finally get their time back." How does Shellac get around the dry time? CND has created a special UV lamp that accommodates both hands and feet and cures the polish as you go. (The machines can easily be completely washed and sterilized between customers.) Shellac paints on just like a regular polish using specially formulated base coat, two layers of color, and top coat. After each coat of polish is applied, you put your hand under the timed lamp while the other hand is being painted. As soon as the manicurist is done with your nails, you can dig into your purse for your keys without any concern of smudging or chipping. They are 100 percent dry in the same time it takes for a normal manicure. I tried scratching at my nails, and even rubbing them along a brick wall--the polish stays put with a gorgeous, shiny finish. Expect your nails to look exactly like this for two weeks. Mine endured sinks full of dishes, harsh cleaning chemicals, and many hours of typing for 16 whole days.
