ABSTRACT Background: Geriatric dermatoses are one of the most common reasons for day-to-day consultation in the elderly. Over the past few years, understanding of the pathophysiology of skin changes in the geriatric age group has improved and has paved the way for better therapeutic options. This article reviews the various physiological and pathological changes of aging, dwelling on the role of intrinsic and extrinsic factors in the pathogenesis of aging skin. To describe the clinical pattern of various dermatological disorders in the elderly. Methods: The study was conducted in the department of Dermatology, Venereology, Leprosy, at Dharmapuri Medical College, Dharmapuri. Totally 150 members were included in the study, who are above the age of 60 years. Thorough systemic and dermatological examination done. Investigations like complete blood count, liver function test, renal function test, random blood sugar were done.

It must be considered today as a true public health problem and the most widespread metabolic bone disease that affects more than 200 million people worldwide. Under physiological conditions, there is a balance between bone formation and bone resorption necessary for skeletal homeostasis. In pathological situations, this balance is altered in favor of osteoclast (OC)-mediated bone resorption. During chronic inflammation, the balance between bone formation and bone resorption may be considerably affected, contributing to a net prevalence of osteoclastogenesis. Skin diseases are the fourth cause of human disease in the world, affecting approximately one third of the world’s population with a prevalence in elderly men.

Physiological changes in aged skin include tionship between sun radiation and skin, especially with structural and biochemical changes as well as changes regards ultraviolet light and the skin aging process. The in neurosensory perception, permeability, response to benefits of sun exposition and the photoaging process are injury, repair capacity, and increased incidence of some discussed. Finally, the authors present a review of photopro- skin diseases (5) . tection agents that are commercially available nowadays. The skin aging process occurs in the epidermis and dermis. Although the number of cell layers remains stable, Keywords: photoaging; sun protection; ultraviolet (UV) the skin thins progressively over adult life at an accelerat- exposure. ing rate. The epidermis decreases in thickness by about 6.4% per decade on average, with an associated reduc- tion in epidermal cell numbers (6) , particularly in women.
