Roles and research progress of postbiotics in skin health

Abstract:

The skin is the largest organ and the carrier of the second largest microbiota in the human body, playing a role in defending against the stimuli from the external environment. External stimuli such as UV rays and fog and haze can cause injuries in the skin, resulting in skin aging or barrier damage. Postbiotics are defined as preparations of inanimate microorganisms or their components that confer health benefits on the host. Recent studies have shown that postbiotics have the potential for maintaining skin health. This article introduces the concept and types of postbiotics and describes the potential role of postbiotics in repairing the skin barrier, promoting wound healing, protecting the skin from photoaging, and regulating the skin microbiota, with the aim of providing a reference for in-depth research on the benefits of postbiotics in skin health and the development of raw materials.
