Why is it important to use a base coat before applying nail polish?

Using a base coat before applying nail polish is essential because it serves multiple key purposes that enhance the overall manicure experience. Primarily, a base coat provides a smooth surface for the polish to adhere to, which helps in achieving a more even and professional finish. This smooth foundation can help prevent streaks and unevenness in the color application.

Additionally, the base coat acts as a protective barrier for natural nails. It helps to minimize the risk of staining that can occur from certain pigments found in nail polishes, particularly darker colors. Staining can result in nails appearing yellow or discolored over time, and a base coat significantly reduces this risk. Therefore, the use of a base coat is crucial for both aesthetic reasons and the long-term health of the nails.
