Immunohistological evaluation of skin responses after treatment using a fractional ultrapulse carbon dioxide laser on back skin.

Background And Objective: Fractional photothermolysis (FP) lasers have been widely used in treating photo-aged skin, acne scars, and other skin conditions. Although plenty of clinical data have demonstrated the efficacy of the FP laser, only limited histologic studies have been available to observe serial short- to long-term skin responses.

Methods: Seven healthy Chinese women received one pass of fractional carbon dioxide laser treatment on the left upper back.

Treatment of infraorbital dark circles using a low-fluence Q-switched 1,064-nm laser.

Objective: To evaluate the efficacy and safety of the low-fluence 1,064-nm Q-switched neodymium-doped yttrium aluminium garnet (QSNY) laser in treating infraorbital dark circles.

Participants And Methods: Thirty women with infraorbital dark circles (predominant color dark brown) participated in this open-label study. Participants underwent eight sessions of low-fluence QSNY laser treatment at 4.

Application of a new intense pulsed light device in the treatment of photoaging skin in Asian patients.

Background: Intense pulsed light (IPL) technology has long been used in the treatment of photoaging skin.

Objective: To evaluate the efficacy and safety of a new IPL device in the treatment of photoaging skin in Asian patients.

Methods: One hundred fifty-two Chinese women with photoaging skin were enrolled in this open-labeled study.
