CND's NEW Brisa Base Coat replaces Brisa Bond with an updated, thicker formula for foolproof application. As a bonding agent that helps adhere gel enhancements to the natural nail, this is the first step in the Brisa Gel System to anchor the Brisa Sculpting Gel for lift-free adhesion and 3+ weeks of wear. This product forms powerful covalent bonds between gel enhancements and natural nails for superior adhesion via Keratin-Bonding, preventing lifting and promoting longer wear.
