Skin Microbiome in Health and Disease: Dysbiosis and the Emerging Role of Biotics in Therapy and Protection
Year: 2026
Type: article
Abstract: The skin functions primarily as a protective physical shield, defending the body against harmful external factors such as invading microorganisms and toxic agents. When this barrier becomes impaired and skin microbiome homeostasis is disturbed, exacerbation of chronic skin diseases may occur, including atopic dermatitis, psoriasis, and acne. This issue became particularly important during the coronavirus pandemic, when it turned out that handwashing and disinfection removed not only impurities and pathogenic microorganisms but also beneficial components of the skin microbiome. This review provides a critical overview of recent advances in understanding the skin microbiome and its influence on skin health, as well as supportive therapies for the treatment of dermatoses. Contemporary therapeutic approaches focus not only on suppressing inflammatory symptoms but also on modulating the skin microbiome as part of a causal treatment strategy, in which prebiotics and probiotics play a significant role. Moreover, probiotics are also considered a valuable component of anti-aging approaches, as they may help counteract the detrimental effects of ultraviolet (UV) radiation on the skin. By reducing oxidative stress, strengthening the epidermal barrier, and exerting immunomodulatory effects, they may complement traditional photoprotection methods. Nevertheless, further research-particularly into their long-term efficacy and safety-is essential to support their broader clinical and consumer application.
