Skin aging is not only a subjective matter of looking attractive or not, It is a real physiological process involving molecular signaling pathways that have effects on skin components. As a consequence of histological changes in the epidermis or collagen fibers’ degradation in the dermis, wrinkles are formed. This process takes place in the natural course of aging but environmental factors, such as sun exposure or smoking, have also an important influence on the aspect of our skin. Several techniques have been developed to objectively evaluate the ageing skin and the efficacy of anti-aging solutions. The treatments that have a proven efficacy in reducing wrinkles are mostly those performed by dermatologists, like hyaluronic acid fihlers or peelings. The cosmetics industry has being inspired by techniques used by aesthetic medicine to create new anti-aging products for home use. Cosmetics are however much less efficient to fight the consequences of time and very few clinical studies support the effects claimed by companies Le vieillissement cutané n’est pas uniquement une impression subjective de beauté. C’est un réel processus physiologique, impliquant des cascades de signalisation moléculaire qui ont un effet sur les composants de la peau. La conséquence des modifications histologiques au niveau de l’épiderme et de la destruction du collagène dans le derme, est l’apparition de rides. Ce processus s’inscrit dans le vieillissement naturel, mais l’environnement, comme l’exposition au soleil ou le tabac, a également une influence importante sur l’aspect de notre peau. Plusieurs techniques ont été mises au point pour évaluer objectivement le vieillissement cutané et l’efficacité des solutions anti-âge. Les traitements ayant prouvé leur efficacité sont principalement ceux effectués par les dermatologues, comme les injections d’acide hyaluronique ou les peelings. L’industrie des cosmétiques a été inspirée par ces techniques utilisées dans la médecine esthétique pour créer des nouveaux produits anti-âge à usage non-médical. Les cosmétiques sont cependant beaucoup moins efficaces pour combattre l’effet du temps et très peu d’études cliniques confirment les effets promis par les firmes.

The high degree of interest for aesthetics and appearance plays an important role in today’s society. Even though this can be nuanced, no one is indifferent to skin aging. If scientists are yet to discover the true “elixir of youth”, numerous products are already used in the field of anti-aging therapy. Amongst those, we find coenzyme Q10, principally used in topical creams, and hyaluronic acid as injectable filler. Let us consider what these products are, how do they work, when they are used and how effective they are. This master thesis aims at clarifying the matter and outlining the current level of knowledge about those anti –aging products as medical devices.

In this new colour handbook the authors deal systematically with those skin conditions that are particular to or more common in the elderly covering testing, diagnosis and treatment options. Given ageing populations the need for such a book is urgent. More and more elderly patients will seek care for a variety of skin conditions, ranging from eczema and psoriasis to benign lesions and skin cancers. For environmental and physiological reasons, all such conditions become more prevalent in the elderly and the effects of treatment more problematic. Following an initial chapter on how skin changes with age, the authors discuss in turn inflammatory, neoplastic, infectious and metabolic/nutritional diseases of the skin, plus skin signs of systemic disease in old age. Skin Diseases of the Elderly is written in a concise structured style and illustrated by a wealth of top quality colour photos. it is intended to help dermatologists in practice and training, geriatricians, primary care physicians, specialist nurses and senior medical students.
