C acnes is a commensal of lipid-rich sebaceous follicles, 2 and routine disinfection of the skin surface is unlikely to impact the viability of microbiota in the reticular dermis. Advances in DNA sequencing technologies have made it possible to detect microbial genome sequences (microbiomes) within tissues once thought to be sterile. Cutibacterium acnes is also capable of producing diverse short chain fatty acids (SCFAs), including propionate, and synthesizing vitamin B 12, and this bacterium is often discussed with respect to the detrimental or beneficial role it plays as a member of the skin microbiota (Brüggemann et al., 2021; Kang et al., 2015; Kao et al., 2021).

We propose that acne vulgaris represents a naturally developing, transient inflammatory interaction of adolescent facial skin with its new microbial/chemical milieu (Cutibacterium acnes, sebum), replacing a state of previous childhood skin homeostasis.This concept might explain why acne is characterized by strong regional and age specificity, prevalent occurrence, and resolution. El examen de la piel de varias personas reveló que la bacteria Cutibacterium acnes está especialmente adaptada a las condiciones de la base de los folículos pilosos, un entorno rico en lípidos. There has been a reported correlation between abnormal growth of lipophilic anaerobic bacteria such as Cutibacterium acnes and the development of acne, but the relationship between microorganisms and acne has not been fully investigated. While the commensal bacterium Propionibacterium acnes (P. acnes) is involved in the maintenance of a healthy skin, it can also act as an opportunistic pathogen in acne vulgaris.The latest findings on P. acnes shed light on the critical role of a tight equilibrium between members of its phylotypes and within the skin microbiota in the development of this skin disease.
