What is "gel overlay" in nail applications?

Gel overlay refers to a technique where a clear gel is applied over the natural nails to enhance their strength and durability. This process involves using a UV or LED light to cure the gel, resulting in a hard, protective coating. The purpose of a gel overlay is to prevent chipping, breaking, and other damage that can occur with regular wear and tear of the nails. It allows for a natural look while providing additional resilience.

The other options do not accurately describe a gel overlay. For instance, painting over natural nails does not provide the strengthening benefits that gel does. A type of nail enhancement done with acrylics refers specifically to acrylic nails, which are different from gel overlays. Lastly, polishing the nail surface focuses on aesthetics rather than structural reinforcement, which is the primary goal of a gel overlay. Thus, the correct understanding of gel overlay as a clear gel application for added strength is essential for nail technicians to provide effective care and enhancements.
