4. Apply polish the right way
To get a perfectly smooth finish, you need to work quickly when applying nail polish However, the strokes you use will also affect the end result. Start in the center, near the cuticle, and gently push down to fill in the rounded space above the cuticle. Then sweep the brush straight up the center of the nail.
Without reloading the brush, move it up each side from the cuticle to the tip. This will redistribute the excess polish and make it look nice and smooth. The trick here is to avoid using too much polish.
