System comprising: a handpiece assembly configured to receive an electromagnetic energy and at least one fluid, and to selectively deliver at least one of the electromagnetic energy and the at least one fluid to a target surface, the handpiece assembly comprising: - a handpiece housing and a plurality of fluid lines extending through the handpiece housing, the plurality of fluid lines being configured to transfer at least one fluid from a proximal end of the handpiece assembly to a distal end of the handpiece assembly; - a spray mixer positioned at the distal end and coupled to fluid lines of the plurality of fluid lines; - an air input port positioned at the proximal end and configured to be coupled to an auxiliary air hose; and an exchangeable disposable applicator configured to be coupled to the distal end of the handpiece housing, the applicator comprising at least one structure configured and arranged to weaken or have reduced mechanical strength or integrity of at least one coupler or clip extending from a main body of the applicator, the at least one coupler or clip being configured and arranged to at least partially secure the disposable tip to the distal end of the handpiece assembly; wherein an air delivery channel of the applicator is coupled to the air input port and configured to supply air to a tip of the applicator; and wherein the applicator is structured so that removal of the applicator from the handpiece assembly causes at least a portion of the applicator to break-away, rendering the applicator non-functional. a handpiece assembly configured to receive an electromagnetic energy and at least one fluid, and to selectively deliver at least one of the electromagnetic energy and the at least one fluid to a target surface, the handpiece assembly comprising: - a handpiece housing and a plurality of fluid lines extending through the handpiece housing, the plurality of fluid lines being configured to transfer at least one fluid from a proximal end of the handpiece assembly to a distal end of the handpiece assembly;
