What does a nail dehydrator remove from the natural nail plate?

A nail dehydrator is specifically designed to prepare the natural nail plate for the application of nail products, particularly enhancements like acrylics or gels. Its primary function is to remove surface moisture and tiny amounts of oil from the nail. The removal of moisture is crucial because any residual moisture can prevent proper adhesion of nail products, leading to lifting or premature failure of the application.

In this context, the focus is on ensuring the nail surface is as clean and dry as possible before applying any enhancements. This is critical for achieving long-lasting results and maintaining the integrity of the manicure. While nail polish residue, dead skin cells, and acrylic dust can also be present on or around the nail during the nail preparation process, a dehydrator's role specifically targets moisture and oils, which are the primary barriers to adhesion for nail products.
