Molecular mechanisms of skin ageing.
Cutaneous ageing is a complex biological phenomenon consisting of two components; intrinsic ageing, which is largely genetically determined and extrinsic ageing caused by environmental exposure, primarily UV light. In sun-exposed areas, these two processes are superimposed. The process of intrinsic skin ageing resembles that seen in most internal organs and is thought to involve decreased proli...
متن کاملSkin ageing and its treatment.
The effects of chronic sun exposure on skin are readily apparent when skin not typically exposed to the sun and skin regularly exposed to the sun are compared. While the sun is not the only aetiological factor in the dynamic process of skin ageing, it is the primary exogenous cause among several internal and environmental elements. Thus, photo-ageing, the main focus of this article, is a subset...
متن کاملImagistic Noninvasive Assessment of Skin Ageing and Anti-Ageing Therapies
The significant increase in life expectancy and the process of population ageing are aspects that generate important social and economic changes and influence the health and research policies throughout the world. The ageing phenomenon represents a natural, slow and irreversible process, which affects all body tissues, being determined by a multitude of factors that contribute in different prop...
متن کاملChanges of Langerhans cells during skin ageing
INTRODUCTION During the process of skin ageing, changes occur in all skin layers and all cells, including the Langerhans cells. AIM To assess whether any quantitative difference in the number of CD1a+ LC cells/mm2 and HLA-DR+ LC cells/mm2 as well as in their morphological features can be observed during the course of different types of skin ageing. MATERIAL AND METHODS The study was conduct...
متن کاملSkin Ageing: Natural Weapons and Strategies
The fact that the skin is the most visible organ makes us aware of the ageing process every minute. The use of plant extracts and herbs has its origins in ancient times. Chronological and photo-ageing can be easily distinguished clinically, but they share important molecular features. We tried to gather the most interesting evidence based on facts about plants and plant extracts used in antiagi...
