What are the best tips for applying iridescent nail polish for a long-lasting and vibrant finish?

To apply iridescent nail polish for a long-lasting and vibrant finish, start with clean, dry nails. Apply a base coat to help the polish adhere better. Shake the polish well before applying thin, even coats. Allow each coat to dry completely before applying the next. Finish with a top coat to seal in the color and add shine. Avoid hot water and harsh chemicals for the first few hours to help the polish set properly.
