What is the best method to ensure the nail polish lasts longer?

Using thin layers of polish is the best method to ensure that the nail polish lasts longer. Applying thin layers allows for better adherence of the polish to both the nail and the base coat, which helps prevent chipping and peeling. Thin layers dry more quickly and evenly, reducing the risk of air bubbles forming underneath the polish. This technique provides a more durable finish while also allowing for the proper curing of each layer.

Applying thick layers, on the other hand, can lead to longer drying times and increase the likelihood of smudging or lifting, as the polish may not set properly. Skipping the base coat compromises the bond between the nail and the polish, which can also lead to early wear. While covering with a second layer immediately might seem beneficial, it often leads to an uneven surface and can trap moisture, further diminishing the longevity of the polish. Therefore, applying thin layers stands out as the most effective method for achieving long-lasting nail color.
