Without performing a fill on acrylic nails, how will the nails begin to appear?

As time goes on without performing a fill on acrylic nails, the growth of the natural nail underneath leads to visible gaps or spaces between the acrylic and the natural nail. This separation creates an uneven, unnatural appearance as the nails grow out, highlighting the difference in length and possibly leading to noticeable lifts at the cuticles. Additionally, the acrylic may start to lose its shine and luster, contributing further to a less polished look. Therefore, the appearance of the nails without a fill will indeed become unnatural and uneven, making this the correct assessment of how the nails will begin to look over time.
