Liquid Prep, often referred to as nail degreaser or nail cleaner, is a cleaning solution specifically formulated for use when applying gel polish to nails. This liquid is designed to thoroughly cleanse and degrease the natural nail. The Prep removes excess oils, dust, and other contaminants from the nail plate. By doing so, it improves the adhesion of the gel polish, allowing it to better bond to the nail surface. A properly cleaned nail plate ensures a longer shelf life of the gel polish and prevents the gel polish from peeling or chipping. It is a crucial step in the overall gel polish application process to ensure a professional result.
