There are two types of aging: a physiological and age-related external factors. Genetically programmed senescence, also called natural or chronological aging. It is due to changes in metabolism: with age gradually suppressed tissue respiration, decreased energy production, slowing the ion transport and other components of metabolic cellular processes. Over time caused by free radicals, sun exposure, environmental hazards is changing the chemical structure of substances that make up the skin. Aging, which is associated with external factors, may be triggered by sunlight and UV radiation, smoking and alcohol consumption, pollution, carcinogens, etc.
Aging and morphological changes of the skin now, there is much data on age morphological changes in the skin. The most significant transformation taking place in the dermis. During physiological aging of the skin decreases the number and size of cellular elements, such as fibroblasts, histiocytes and mast cells. Fibroblasts significantly reduced its activity on the development of such important proteins like collagen, elastin, an amorphous components of connective tissue. The fibroblasts of the dermis can shrink - just as well as muscle cells. This decrease provokes the growth of degenerative processes in the relevant areas of the skin. Therefore, it becomes clear why the wrinkles are formed due to the constant stress in the zone of the dermis. During each year of life, collagen production is reduced by 1%.
Gradually, the collagen fibers begin to atrophy and not placed so tightly, like a young age. Special attention needs clarification changes in the composition of collagen. Cerebral contributes greatly to this topic. It is collagen type III saturates skin with moisture, making it soft and velvety.
