What is a common benefit of using a base coat prior to nail polish application?

1. It helps the polish to dry faster

2. It enhances the color of the polish

3. It prevents staining of the natural nail

4. It increases chip resistance

The correct answer is: It prevents staining of the natural nail

Using a base coat prior to nail polish application serves several important purposes, one of which is the prevention of staining on the natural nail. When colored polishes, particularly darker shades, are applied directly onto the natural nail without a protective base layer, there is a risk of the pigments from the polish penetrating the nail plate, which can lead to discoloration and yellowing over time. A well-formulated base coat creates a barrier that protects the nail, effectively reducing the chances of such staining and maintaining the health and appearance of the natural nails. This protective property makes the use of a base coat essential not only for aesthetic purposes but also for long-term nail health, promoting a visually appealing result without compromising the natural nail underneath.
