During a stress test on acrylic nails, which part of the nail should be evaluated?

When performing a stress test on acrylic nails, the primary focus is on the free edge of the nail. The free edge is the part of the nail that extends beyond the fingertip and is crucial for assessing the strength and durability of the acrylic application. During the stress test, a technician checks how well the acrylic holds up under pressure, bending, and potential impacts.

The free edge is particularly significant because it is the area most likely to experience wear and tear in everyday activities. Evaluating this part of the nail helps determine if the acrylic is properly adhered, is of suitable thickness, and can withstand normal stress without breaking or lifting.

In contrast, other areas such as the cuticle, nail bed, and sidewalls have their own importance in the overall health and aesthetics of the nail but are not the primary focus during a stress test specifically aimed at determining the integrity of the acrylic nails under pressure.
