Photoeradication of Helicobacter pylori using 5-aminolevulinic acid: preliminary human studies.

abstract：BACKGROUND AND OBJECTIVES:Intense pulsed light (IPL) is regarded as the gold standard of nonablative photo-rejuvenation. Yet there is still a need to observe its efficacy and safety on dark skin using a split-face module. STUDY DESIGN/MATERIALS AND METHODS:Twenty-four Chinese women with photoaging were enrolled in thi...
