Aging of the skin is a composite of actinic damage, chronologic aging, and hormonal influences. The majority of changes associated with aging, such as wrinkles and solar lentigines ("liver spots"), are due to photoaging and reflect cumulative sun exposure as well as skin pigmentation. Classically, chronologic aging includes those cutaneous changes that

Abstract Neuropeptides (NP) are peptides that are released as chemical messengers from nerve cells. They act either in an endocrine manner, where they reach their target cells via the bloodstream or a paracrine manner, as co-transmitters modulating the function of neurotransmitters.

Cancer affects two major cell types in the human skin: epithelial cells and melanocytes. Aging and a previous history of ultraviolet light exposure are major risk factors for skin cancers, including basal and squamous cell carcinomas and melanomas. However, melanomas, which are the most deadly of the skin tumors, display two intriguing characteristics:

Androgens and ageing of the skin
Current Opinion in Endocrinology, Diabetes & Obesity, 2009This study reviews current advances in our understanding of the role of androgens in the initiation of skin ageing.Skin and its appendages being a steroidogenic tissue itself can be affected to a large extent by sex steroids. Amongst them, androgens display a distinguished role.

AbstractSkin aging appears to be the result of both scheduled and continuous “wear and tear” processes that damage cellular DNA and proteins. Two types of aging, chronological skin aging and photoaging, have distinct clinical and histological features. Chronological skin aging is a universal and inevitable process characterized primarily by physiologic

Physiologic, biochemical and microscopic changes in the aged skin are due to past environment, heredity and the aging process. These factors and the response of aging skin to the elements and to physical or chemical trauma cause degenerative processes which produce cutaneous lesions.Lesions most frequently seen in the aged are keratoses, skin tags ...

Ethnic skin is quickly emerging as the norm in the United States, and as the population becomes more diverse, there is also a projected rise in the number of aging adults. Given the paucity of data regarding aging in ethnic skin, the authors have consolidated available information for this population.

The environment and skin aging
Clinics in Dermatology, 1998A side from the relentless changes of aging that one endures over a lifetime, our environment usually contributes additional insult on the integument, especially on those areas of the body that are exposed to the elements. Many of the effects of environmental exposure (ie extrinsic aging) can be difficult to distinguish clinically from the naturally ...

Reviews in Endocrine and Metabolic Disorders, 2016
Aging is a complex process not only influenced by inherited but also by several environmental factors. It is characterized by a progressive loss of function in multiple tissues, which leads to an increased probability of death. On the other hand, several morphological and histological changes are registered in aged skin that is mostly dependent on the ...

Ageing Research Reviews, 2004
Elderly individuals have an increased susceptibility to skin infections due to age-related anatomical, physiological and environmental factors. The types of organisms that cause primary skin and soft tissue infections are diverse, and include bacterial, viral and fungal pathogens as well as parasites.
