• Before you start your manicure, wipe polish remover over each nail to ensure your nails are clean and dry. • Gently roll the bottle of nail color between your palms to mix the color (don't shake, which can trigger those dreaded air bubbles). • Brush a thin coat of the nail polish over each bare nail, dipping the brush back into the bottle for each finger. • Wait 2 minutes, then apply a second coat of color.
