Depending on which laser is being used, a careful history should be obtained. For pediatric patients with vascular lesions, a history of seizures and a careful review of systems should be completed. A detailed history helps detect syndromes associated with vascular lesions, such as Sturge-Weber syndrome and Klippel-Trenaunay syndrome. More than one treatment session is necessary in most cases of vascular lesion ablation, and this should be explained to the patient.

Tattoos generally require several treatment sessions. Colors respond differently to the various wavelengths due to selective photothermolysis of each particular wavelength. Pigment changes may occur with tattoo removal. Generally, patients with Fitzgerald skin type I or II experience hypopigmentation of the treated tattoo, and patients should be informed of this potential. Similarly, type III or IV skin may become hyperpigmented.
