Chicken or the egg in Acne?

This article[1] reiterates the role of antimicrobial peptides (AMP), the body’s innate antimicrobial system in the pathogenesis and management of acne. Yes, there is a paradox here! AMP because of its anti-p.acnes action may improve acne while its proinflammatory properties may worsen it. It is not known whether p.acnes indirectly causes inflammatory acne by promoting AMP production. The authors examines several endogenous AMPs and gets unduly enticed in this Chicken-Egg paradox making too many speculations. However the bottom line seems to be simple and straightforward: Structurally modified AMPs and AMPs from other species with less proinflammatory properties may be useful in acne.
