Which area of the nail does an acrylic overlay get its strength from?

An acrylic overlay derives its strength primarily from the apex of the nail. The apex is the highest point or the arch of the nail, which plays a crucial role in providing strength, support, and structure to the nail enhancement. This area is typically built up more than the surrounding areas to enhance durability, enabling the acrylic overlay to withstand pressure and daily wear without breaking or chipping.

The apex serves as a central reinforcement, allowing the product to distribute stress evenly across the nail surface. A well-formed apex ensures the integrity of the entire nail enhancement. While other areas such as the tip, base, and sidewalls contribute to the overall appearance and shape, it is the apex that is critical for the added strength and stability of an acrylic overlay.
