Propionibacterium acnes naturally produces endogenous porphyrins that are composed of coproporphyrin III (CPIII) and protoporphyrin IX (PpIX). Red light alone and photodynamic therapy (PDT) improve acne vulgaris clinically, but there remains a paucity of quantitative data that directly examine the bactericidal effects that result from PDT on P. acnes itself in vitro. The purpose of this study was to measure the difference of bactericidal effects of 5-aminolevulinic acid (ALA)-PDT with red and… CONTINUE READING
