What should be done to ensure the correct application of nail polish?

Applying a base coat is essential for ensuring the correct application of nail polish. The base coat serves several important functions: it acts as a primer for the nail, helping to create a smoother surface for the color polish to adhere to, which can enhance the overall appearance and longevity of the manicure. Additionally, the base coat protects the natural nail from potential staining that can occur from darker nail polishes, thus preserving the health and color of the natural nail underneath. Using a base coat is a standard practice in nail care because it not only improves the application process but also contributes to a polished look and extended wear of the nail polish.

In contrast, the other options may lead to less effective application or negatively impact the nail’s health and polish durability. Skipping the top coat can result in a less durable finish, while using thick layers of polish can lead to an uneven texture and longer drying times, increasing the likelihood of smudges. Limiting to only one type of polish does not allow for versatility or options that could enhance the manicure experience.
