The versatility of lasers has truly manifested itself in various medical and cosmetic procedures. Patients consider a number of benign pigmented cutaneous lesions objectionable because of their color, size, number, or location. These lesions include lentigines, café-au-lait macules, ephelides, junctional nevi, seborrheic keratoses, dermal melanosis, and tattoos . Removal of these lesions involves destroying the epidermis to remove the unwanted lesion. For superficial lesions, physicians can treat these lesions with multiple modalities. In addition, almost all epidermal injuries heal without scarring. For deep dermal pigmented lesion, however, selective damaging to the lesions usually is performed by using the Q-switched laser systems.
