- Lasting Duration
The lasting duration of nail polish can be evaluated through a clinical test. For this test, nail polish is applied to the nails of a group of participants, and the duration of the nail polish's appearance is monitored over time. The nail polish's performance is evaluated by analyzing the time it takes for the polish to chip, fade or peel off the nails. The test can be conducted using a range of variables, including the type of nail polish, the number of coats applied, the application technique, and the environmental factors that affect the nail polish's performance.
The test is performed using image analysis software used to monitor changes in the nail polish's appearance over time. The results of this test provide valuable data on the quality and durability of the nail polish, which can be used to improve the product's formulation and to develop marketing claims based on its performance.
