What is a recommended technique to enhance the wear of a manicure?

Using a top coat is a recommended technique to enhance the wear of a manicure because it acts as a protective layer over the colored polish. The top coat seals the color underneath, helping to prevent chipping, fading, and wear from daily activities. It not only adds shine but also extends the longevity of the manicure, making it look fresh for a more extended period.

A base coat serves a different purpose; it helps the polish adhere better and protects the natural nail, but skipping its application might not directly enhance the wear of the manicure itself. Applying nail polish on oily nails can lead to poor adhesion, resulting in premature wear or peeling of the lacquer. While darker polish colors may sometimes show chips less noticeably, they do not inherently enhance the wear of the manicure in the way a top coat does. Thus, using a top coat is the most effective method among the options provided for ensuring a longer-lasting manicure.
