Abstract summary (English) BACKGROUND: Laser toning using low-fluence 1064-nm Q-switched neodymium-doped yttrium aluminum laser (QSNY) has gained popularity in the treatment of photoaging-associated mottled pigmentation (PMP). However, hypopigmentation or lack of efficacy has been reported depending on the fluences used. OBJECTIVE: To compare a novel fractional 1064-nm QSNY with conventional 1064-nm QSNY for the treatment of...

Abstract summary (English) BACKGROUND: Q-switched laser treatment for pigment disorders commonly leads to postinflammatory hyperpigmentation (PIH) in Asians. OBJECTIVES: To evaluate the effect of spot size and fluence on Q-switched alexandrite laser (QSAL) treatment for pigmentation in Asians. METHODS: Ten patients with freckles, 18 with lentigines, and 8 with acquired bilateral nevus of Ota-like macules (ABNOM) received 1 session of QSAL...

Abstract summary (English) Although frequently performed, laser removal of pigmented lesions still contains certain controversial issues. Epidermal pigmented lesions include solar lentigines, ephelides, café au lait macules and seborrheic keratoses. Dermal lesions include melanocytic nevi, blue nevi, drug induced hyperpigmentation and nevus of Ota and Ito.

Abstract summary (English) AIM: There are still insufficient clinical reports concerning quality-switched Nd:YAG laser (QSNYL) in the treatment of superficial pigmented lesions in Asians. The purpose of this study was to analyse the efficacy and side effect profiles of QSNYL-assisted pigment removal in brown skin. METHODS: A total of 71 patients, presenting a wide gamut of superficial epidermal lesions, were treated with QSNYL.
