What is a key benefit of proper nail polish application technique?

The key benefit of proper nail polish application technique is that it ensures a long-lasting finish. When nail polish is applied correctly, it adheres better to the nail surface and is less prone to chipping or fading. This involves various steps, such as properly preparing the nail by cleaning and buffing, applying a base coat, and sealing the polish with a top coat. Each of these steps helps enhance the durability of the polish, allowing for a polished look that can last days or even weeks without significant wear.

In contrast, other options do not provide the same direct benefit. For example, while proper application is important for the aesthetics of nails, it does not affect the need for nail trimming, nor does it provide nutrition to the nails or enhance sensitivity in the nail bed. Therefore, focusing on the technique of applying nail polish directly contributes to the longevity of the cosmetic result, making it a crucial skill for nail technicians.
