Aging of the skin is a complex biological process. The process of skin aging can be divided into two categories namely intrinsic and extrinsic aging. Intrinsic skin aging or natural aging is caused by changes in skin elasticity that occur with age. This type of aging cannot be prevented. While extrinsic skin aging is caused by environmental factors such as exposure to solar radiation (photoaging). In this study, the type of research approach used is a type of qualitative research through a literature review. The type of data used is the type of secondary data. Secondary data is a type of data

Skin aging is intrinsic and extrinsic. Intrinsic, or chronological, skin aging is an inevitable process of chronological and physiological alterations. The factors contributing to extrinsic skin aging involve sunlight, nutrients, and stress. Thus, extrinsic aging is thought to be superimposed over intrinsic aging and depends on the intensity and duration of environmental exposure and skin type (e.g., dry skin, oily skin, or eczema). The most significant extrinsic aging factor is UV radiation, which causes cellular senescence in a process known as photoaging. This study aimed to illuminate the

Abstract Aging is of two types, namely extrinsic and intrinsic aging. Extrinsic aging or photoaging is caused mainly due to damage caused by solar radiation. We report the case of a elderly male who presented with large growth on the scalp and ulcer on the face. However, on clinical examination, almost all the changes of photoaging, namely solar lentigo, cutis rhomboidalis nuchae squamous, and basal cell carcinoma were present. This case highlights the importance of thorough clinical examination needed in the geriatric population for the early diagnosis and timely management of their ailments.

Abstract Melanoma is the deadliest form of skin cancer, with its incidence rising disproportionally to other cancers. Chronological aging is a major risk factor in all types of cancer as it has been shown to drive changes in noncancerous cells (stromal and immune) of the tumor microenvironment (TME) to promote tumor initiation and progression. Ultraviolet radiation (UVR) exposure, which is a major risk factor for melanoma, also can cause a physical premature aging phenotype, known as photoaging.

Photoaging is an important extrinsic aging factor leading to altered skin morphology and reduced function. Prior work has revealed a connection between photoaging and loss of subcutaneous fat. Currently, primary models for studying this are in vivo (human samples or animal models) or in vitro models, including human skin equivalents (HSEs). In vivo models are limited by accessibility and cost, while HSEs typically do not include a subcutaneous adipose component. To address this, we developed an “adipose-vascular” HSE (AVHSE) culture method, which includes both hypodermal adipose and vascular c

Tropical countries worldwide are frequently subjected to high levels of sunlight year-round. This leads to concerns about potential harmful effects, including skin damage resulting from oxidative stress caused by free radicals due to prolonged sun exposure. This results in extrinsic skin aging, or photoaging. Sunscreen, as a primary photoprotection, is commonly recommended to protect the skin from sunlight. However, even sunscreens with high SPF cannot provide 100% protection from damage caused by free radicals generated by UV rays. Therefore, secondary photoprotection such as natural antioxid

Skin, being one of the vital organs and a protective barrier needs to be pampered and taken care of from early childhood. It is the most visible and the widest exposed organ and by far reflects the general health condition and the aging process in humans. Both intrinsic and extrinsic factors contribute to this complex biological process of skin aging. In recent times, skin health and its beauty is perceived as an indicator of one’s health which has resulted in an increasing demand for anti-aging products. Exposure to UV radiation is considered to be one of the factors responsible for aging ter

Extracellular vesicles, which are highly conserved in most cells, contain biologically active substances. The vesicles and substances interact with cells and impact physiological mechanisms. The skin is the most external organ and is in direct contact with the external environment. Photoaging and skin damage are caused by extrinsic factors. The formation of wrinkles is a major indicator of skin aging and is caused by a decrease in collagen and hyaluronic acid. MMP-1 expression is also increased. Due to accruing damage, skin aging reduces the ability of the skin barrier, thereby lowering the sk

Among various internal and external factors related to aging, ultraviolet (UV) radiation is the main cause of photoaging of the skin. UV radiation stimulates DNA damage, reactive oxygen species (ROS) generation, and pro-inflammatory cytokine production such as tumor necrosis factor-alpha (TNF-α), and promotes ECM degradation.
