High-fluence 1064-nm Q-Switched Nd:YAG laser: Safe and effective treatment of café-au-lait macules in Asian patients.

Objectives: Café-au-lait macules (CALMs) are benign cutaneous hyperpigmentary disorders. Usually, laser therapies for cosmetic concerns result in more severe side effects in the people of Asian descent than that of Caucasians. Unfortunately, there is no gold standard for the laser treatment of CALMs in skin of people of Asian descent.

Treatment of erythematotelangiectatic rosacea with the fractionation of high-fluence, long-pulsed 595-nm pulsed dye laser.

Various lasers have been used for the treatment of erythematotelangiectatic rosacea (ETR) that does not respond to systemic or topical therapy. The pulsed dye lasers (PDLs) are an effective option for ETR, and the purpuragenic fluence proved to be superior until now. Given that purpura and subsequent possible postinflammatory hyperpigmentation (PIH) are occasionally unbearable in some patients, and several studies using the low nonpurpuragenic fluence were reported.

Assessment of treatment efficacy and sebosuppressive effect of fractional radiofrequency microneedle on acne vulgaris.

Background And Objective: A minimally invasive fractional radiofrequency microneedle (FRM) device has been used in skin rejuvenation and acne scars, and a recent pilot study demonstrated the positive therapeutic effect on acne. We evaluated the efficacy of FRM device for acne vulgaris in Asians and conducted objective measurement to assess its effect on sebum production.

Patients And Methods: Twenty Korean patients with acne vulgaris received a single full-face FRM treatment.
