Use of a Fractional Q-Switched Ruby Laser for Treatment of Facial Lentigines

Introduction: Fractional laser technology is associated with decreased posttreatment morbidity but has not been applied to Q-switched ruby lasers (694 nm). Standard Q-switched ruby lasers have been used effectively for the treatment of pigmented lesions but require postoperative wound care and significant recovery time. The objective is to report on the suitability of a new fractional handpiece for a Q-switched ruby laser for the treatment of facial lentigines. Materials and Methods: Five patients with facial lentigines were treated with or without topical anesthetic with a fractional Q-switched ruby laser at a fluence that caused tissue whitening. Results: Patients were treated 1 to 2 times. All patients experienced clinical improvement in hyperpigmentation with minimal posttreatment erythema and crusting. Conclusions: The fractional Q-switched ruby laser is an ideal treatment for facial lentigines, causing clinical improvement with minimal posttreatment morbidity.
