This review discusses various aspects of cellular senescence in human skin, including physiology, pathology, and signaling pathways. Cellular senescence can have both beneficial and detrimental effects on the skin, indicating the need for both pro-senescent and anti-senescent therapies depending on the context. Understanding the molecular mechanisms of skin cellular senescence may provide insights for developing effective therapeutics for senescence-related skin disorders.
Despite the growing interest by researchers into cellular senescence, a hallmark of cellular aging, its role in human skin remains equivocal. The skin is the largest and most accessible human organ, reacting to the external and internal environment. Hence, it is an organ of choice to investigate cellular senescence and to target root-cause aging processes using senolytic and senomorphic agents, including naturally occurring plant-based derivatives. This review presents different aspects of skin cellular senescence, from physiology to pathology and signaling pathways. Cellular senescence can have both beneficial and detrimental effects on the skin, indicating that both prosenescent and antisenescent therapies may be desirable, based on the context. Knowledge of molecular mechanisms involved in skin cellular senescence may provide meaningful insights for developing effective therapeutics for senescence-related skin disorders, such as wound healing and cosmetic skin aging changes.
