Natural Strains Producing Unique Bioactive Ingredients and Their Applications in Skincare

With growing insights into the skin microbiome and advances in biotechnology, the application of natural bacterial strains as active ingredients in skincare products is gaining increasing recognition. This article provides a comprehensive review of naturally derived microbial strains from specific environments, focusing on the diverse benefits of their unique bioactive compounds for maintaining skin health. It elaborates on how these strains contribute to skincare by modulating the skin's microbial balance, strengthening the skin barrier, inhibiting pathogenic bacteria, and promoting collagen synthesis. The use of cutting-edge technologies such as fermentation engineering and synthetic biology for efficiently producing these bioactive substances is also discussed. Furthermore, the paper addresses current challenges in strain selection, safety evaluation, and industrial-scale production, while offering perspectives on future developments, aiming to support both scientific research and practical applications in this field.
