          Abstract

          RESUMEN Entre los factores actualmente identificados en la aparición del acné se encuentra la proliferación bacteriana de Cutibacterium acnes debida a la seborrea y la hiperqueratosis. Los tratamientos tópicos para el acné son estrictamente necesarios y van desde antibióticos hasta ácido salicílico dependiendo siempre del tipo de acné que se desee tratar. Los mecanismos de acción principales de los productos de uso tópico para esta enfermedad van encaminados a eliminar el exceso de bacterias de la piel y reducir el proceso de enrojecimiento y la inflamación. Para el tratamiento de esta enfermedad se desarrollaron dos cremas utilizando dos concentraciones de OLEOZON® tópico como ingrediente farmacéutico activo, con polisorbato 80 como agente emulgente y otros excipientes. Se realizó un estudio de estabilidad durante seis meses, el cual mostró su comportamiento a las dos temperaturas de almacenamiento (2-8˚C y 30˚C) desde el punto de vista organoléptico, físico-químico y microbiológico. Este último demostró una marcada actividad antimicrobiana y ausencia de microrganismos en las muestras durante los seis meses de estudio. Las propiedades organolépticas mostraron mejores resultados a bajas temperaturas de almacenamiento, ya que se mantuvieron uniformes en cuanto a color, olor y textura; de igual forma la evaluación físico-química corroboró un mejor comportamiento para las cremas almacenadas a bajas temperaturas.

          ABSTRACT Among the factors currently identified in the appearance of acne is the bacterial proliferation of Cutibacterium acnes due to seborrhea and hyperkeratosis. Topical acne treatments are strictly necessary and range from antibiotics to salicylic acid depending on the type of acne to be treated. The main mechanisms of action of topical products for this disease are aimed at eliminating excess bacteria from the skin and reducing the process of redness and inflammation. For the treatment of this disease, two creams were developed using two concentrations of topical OLEOZON® as active pharmaceutical ingredient, with polysorbate 80 as emulsifying agent and other excipients. A stability study was performed for six months, which showed its behavior at the two storage temperatures (2-8˚C and 30˚C) from the organoleptic, physicochemical and microbiological point of view, the latter showed a marked antimicrobial activity and absence of microorganisms in the samples during the six months of study. The organoleptic properties showed better results at low storage temperatures, since they remained uniform in terms of color, odor and texture; likewise, the physicochemical evaluation corroborated a better performance for the creams stored at low temperatures.

          The human skin microbiome

          Functioning as the exterior interface of the human body with the environment, skin acts as a physical barrier to prevent the invasion of foreign pathogens while providing a home to the commensal microbiota. The harsh physical landscape of skin, particularly the desiccated, nutrient-poor, acidic environment, also contributes to the adversity that pathogens face when colonizing human skin. Despite this, the skin is colonized by a diverse microbiota. In this Review, we describe amplicon and shotgun metagenomic DNA sequencing studies that have been used to assess the taxonomic diversity of microorganisms that are associated with skin from the kingdom to the strain level. We discuss recent insights into skin microbial communities, including their composition in health and disease, the dynamics between species and interactions with the immune system, with a focus on Propionibacterium acnes, Staphylococcus epidermidis and Staphylococcus aureus.

            Biogeography and individuality shape function in the human skin metagenome

            Summary The varied topography of human skin offers a unique opportunity to study how the body’s microenvironments influence the functional and taxonomic composition of microbial communities. Phylogenetic marker gene-based studies have identified many bacteria and fungi that colonize distinct skin niches. Here, metagenomic analyses of diverse body sites in healthy humans demonstrate that local biogeography and strong individuality define the skin microbiome. We developed a relational analysis of bacterial, fungal, and viral communities, which showed not only site-specificity but also individual signatures. We further identified strain-level variation of dominant species as heterogeneous and multiphyletic. Reference-free analyses captured the uncharacterized metagenome through the development of a multi-kingdom gene catalog, which was used to uncover genetic signatures of species lacking reference genomes. This work is foundational for human disease studies investigating inter-kingdom interactions, metabolic changes, and strain tracking and defines the dual influence of biogeography and individuality on microbial composition and function.
