One questions that is common among medical practitioners, tattoo artists, electrologists, consumers and others who require adequate skin numbing for minor skin conditions and procedures is: do topical anesthetics work?
Many options to deliver anesthesia have developed over the last several decades. Administration of topical anesthetics to control pain associated with procedures such as laceration repair may avoid the need for infiltration local anesthesia injections and associated pain from the injections. Topical anesthesia also avoids the risk of wound margin distortion that exists with infiltration injection administration. Many dosage forms exist (eg, gels, sprays, creams, ointments, patches) and provide the clinician with precise options for application under various circumstances.
