Microbial guardians of skin health (2019): http://science.sciencemag.org/content/363/6424/227 "Here, we focus on Staphylococcus epidermidis as a “poster child” of the skin microbiota to illustrate the remarkable diversity of functions a microbe can exert on skin physiology and health"

Minor taxa in human skin microbiome contribute to the personal identification (2018): http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0199947

MAVS deficiency induces gut dysbiotic microbiota conferring a proallergic phenotype (mice, 2018): https://doi.org/10.1073/pnas.1722372115 "Collectively, we unveiled an unexpected impact of RIG-I–like signaling on the gut microbiota with consequences on allergic skin disease outcome. Primarily, these data indicate that manipulating the gut microbiota may help in the development of therapeutic strategies for the treatment of human allergic skin pathologies"

Ultraviolet radiation, both UVA and UVB, influences the composition of the skin microbiome (2018): https://doi.org/10.1111/exd.13854

The human skin microbiota is a rich source of bacteriocin producing staphylococci which kill human pathogens. (2018): https://doi.org/10.1093/femsec/fiy241

Acne:

Acne vulgaris patients have a distinct gut microbiota in comparison with healthy controls (2017): http://www.jidonline.org/article/S0022-202X(17)32017-1/fulltext

Gut microbiota alterations in moderate to severe acne vulgaris patients (2018): https://onlinelibrary.wiley.com/doi/abs/10.1111/1346-8138.14586

contrary to what was previously thought, proliferation of P. acnes is not the trigger of acne as patients with acne do not harbour more P. acnes in follicles than normal individuals. Instead, the loss of the skin microbial diversity together with the activation of the innate immunity might lead to this chronic inflammatory condition (2018): https://onlinelibrary.wiley.com/doi/full/10.1111/jdv.15043

Isotretinoin and lymecycline treatments modify the skin microbiota in acne. This study provides insight into the skin microbiota in acne and how it is modulated by systemic acne treatment. https://old.reddit.com/r/HumanMicrobiome/comments/6jdml4/isotretinoin_and_lymecycline_treatments_modify/
