What technique is recommended for applying nail polish to avoid bubbles?

Applying thin layers of nail polish is recommended to avoid bubbles because it allows for better control of the application and ensures that the product adheres evenly to the nail surface. When thick layers are used, the polish can take longer to dry, increasing the risk of trapping air bubbles within the polish as it settles. The application of thinner coats, usually followed by multiple layers, helps to create a smoother finish while also providing adequate drying time between applications.

Using a sponge technique, while useful in some nail art applications, is not typically employed for a basic polish application with the aim of preventing bubbles. Brushing quickly can lead to uneven application and does not address the underlying issue of air entrapment. Overall, the approach of applying thin layers is foundational in professional nail care, promoting a cleaner, more polished appearance.
