This document discusses acne and Propionibacterium acnes bacteria. It notes that P. acnes lives naturally on the skin and overproduces when pores are clogged. While antibiotics can help treat severe acne, they are not recommended for long-term use due to risk of antibiotic resistance. The document recommends treating acne through a skincare routine of gentle cleansing, application of non-comedogenic products, and avoiding excessive stress.
