Background: Dyspigmentation is a common cosmetic concern among Asians. Many individuals exhibit mixed pigmentary entities including melasma, flat/small seborrheic keratoses, ephelides, solar lentigines and acquired bilateral nevus-of-Ota-like macules (ABNOM). We term this phenomenon complex dyspigmentation (CD) and suggest that a combination strategy may be more efficacious than any singular modality. Objective: To determine the effectiveness of combined intense-pulsed light (IPL) for global photorejuvenation along with Q-switched ruby laser (QSRL) for targeted pigment dissolution. Study Design/Materials and Methods: Twenty-five Korean women with CD (defined as > 2 types of facial pigmentary disorders) were initially treated with IPL followed by repeat treatments every 3-4 weeks as needed. The QSRL treatments, set at low fluence, were added either during the same session or within 1 week of the IPL treatment. Improvement was assessed by the patient, the treating physician and a blinded evaluation of pre-and post-treatment photographs. Results: Using a 4-point scale (1 ¼ poor, 2 ¼ fair, 3 ¼ good, 4 ¼ excellent), 19/25 patients (76%) reporting good-to-excellent response (score ''3'' or ''4''). Two independent physician assessment revealed that 15/25 patients (60%) showed 76-100% improvement while 19/25 patients (76%) showed at least 50% improvement. Side-effects were minimal: 3 patients had transient post-inflammatory hyperpigmentation (12%) and 1 patient (4%) had linear hypopigmentation. Conclusions: Combination treatment with IPL and QSRL is an effective and safe treatment for CD among Asian patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
