Dermabrasion is an excellent modality for the treatment of acquired nevus of Ota-like macules.

background. Dark lip is a common cosmetic problem in Southeast Asia. There is no known effective treatment. objective. To propose an effective method for treating dark lips of varying causes with frequency-doubled Q-switched Nd: YAG laser. methods. Seventy patients with dark lip, of which 22 were congenital, 24 acquired, and 24 of uncertain cause, were treated by frequency-doubled Q-switched Nd:YAG laser at a fluence of 2-3.5 J/cm 2 (mode 2.5 J/cm 2 ) after application of topical anesthesia. The endpoint of treatment was complete clearance of the pigment. Follow-up time was 24-36 months (mean 29 months).

Café-au-lait macules are skin lesions known to resist all kinds of treatment. Green light at a wavelength of 511 nm from a copper vapour laser through a built-in computerized scanner (SCANALL) was employed to treat café-au-lait-macules in 16 patients. The laser was used in continuous mode with a mean energy density of 8.9 J/cm2 (range 7-22 J/cm2). The mean number of treatment sessions was two. The response was good to excellent in 15 cases and poor in one. Transient hyperpigmentation at the periphery and temporary non-homogeneous hypopigmentation at the centre of the treated area was observed in some cases. These eventually returned to normal after a few months, without any textural change. Pre- and postoperative histological finding are also presented. There was no recurrence at a mean follow-up time of 22 months. Copper vapour laser is an effective modality for the treatment of café-au-lait macules.

Dark lip can be effectively treated by frequency-doubled Q-switched Nd:YAG laser without major adverse effects.
