Topical Application of Engineered Lactobacillus Reuteri With a Zinc Sulfate-Tannic Acid MPN Coating for Acne

A growing body of evidence suggests that the development and progression of acne are closely linked to an imbalance in the skin's microbial community. Compared to healthy skin, the composition and function of the microbiota in acne lesions are significantly altered. This microbial imbalance is believed to drive the formation and recurrence of acne through mechanisms such as triggering abnormal inflammatory responses and compromising the skin barrier. An in-depth exploration of the interaction between acne and the skin microbiome not only offers new perspectives for understanding the root causes of the disease but also lays the groundwork for developing novel treatment strategies aimed at modulating the microbiota. Therefore, identifying innovative approaches that integrate acne treatment with the regulation of microbial balance holds significant clinical and social value. Although existing acne treatments have made progress, research focusing on interventions that regulate the local skin microecology through probiotics remains relatively limited. This study aims to explore a new strategy based on skin microecological modulation. Investigators are using a common probiotic-Lactobacillus reuteri-and applying an engineering modification with a special coating formed by zinc sulfate and tannic acid (MPN coating). This modification is intended to enhance the bacterium's survival and colonization on the skin, thereby more effectively regulating the local microbiota and reducing in…
