This document summarizes how Propionibacterium acnes (P. acnes) promotes comedones and causes inflammatory responses in the skin. It discusses five ways P. acnes promotes comedones: through biofilms, the IGF pathway, aberrant integrin expression, production of free fatty acids, and oxidation of squalene. It also lists natural extracts and compounds that can target each of these mechanisms. Additionally, it outlines several inflammatory cytokines and receptors induced by P. acnes, and recommends natural extracts shown to inhibit each one. The document promotes learning more about these topics by visiting the provided website or contacting the listed email.
