What is a result of not rebalancing or redoing a fill on acrylic nails?

Choosing to not rebalance or redo a fill on acrylic nails can lead to unevenness and an unnatural appearance. Over time, as the natural nail grows out, the acrylic can become out of alignment with the nail bed, resulting in gaps or lifted areas. This not only affects the aesthetics of the nails but can also expose the natural nail in areas, contributing to an inconsistent and less polished look. Regular rebalancing is essential to maintain the shape and smoothness of the acrylic, ensuring they appear well-maintained and visually appealing.

The other choices focus on different aspects that may arise from neglecting nail care, such as thickness or susceptibility to chipping and infection, but the primary and most immediate visual impact of not maintaining acrylic nails is the development of an unnatural and uneven appearance.
