Abstract:
Skin aging is influenced by both intrinsic and extrinsic factors. The gradual manifestation of changes in telomere length and telomerase activity, as crucial indicators of aging, elucidates the underlying mechanism of skin aging. This review aims to comprehensively analyze the association between telomeres and aging, along with their impact on skin biological function. Firstly, we summarize the structure and function of telomeres and their role in cell division. Subsequently, we discuss the mechanisms through which telomere regulation contributes to aging processes while analyzing its involvement in skin aging by elaborating on biological markers. Furthermore, this paper presents a summary of recent research progress that reveals the correlation between telomere length and skin aging as well as model building methods; it also proposes telomere length as a potential indicator for predicting skin aging. Finally, anti-aging strategies based on telomere protection are discussed including drug therapy and lifestyle adjustments. This paper provides a systematic overview of the role played by telomeres in the field of skin aging for the first time, offering new perspectives and ideas for future prevention and treatment.

The Effect of Aging on Tissues
Cells of the Epidermis
The cells in all these layers except the stratum basale are called keratinocytes, a type of cell that manufactures and stores the protein keratin. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from...
Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
