Side effects of non-ablative lasers and radiofrequency treatments are generally mild and transient. Local erythema and edema are typically observed in treated skin; however, a small percentage of patients in these studies experience superficial burns, ecchymoses, dysesthesias, and vesiculation [59, 71–74]. Mild to moderate discomfort which intensifies at higher fluences is typical despite the use of topical anesthesia and tissue cooling techniques, thereby leading many practitioners to add oral sedation and/or anesthetic nerve blocks.
