What happens, when the skin grows old?
The first small wrinkles on the face are always small wrinkles of by-play.
They arise because the muscles of specific sections of the face constantly
extend elastic fibers of connecting tissues.
Collagen fibers of a connecting tissue play also the big role together with
elastin fibers in ageing of the skin. Both types of fibers form a dense network,
which is sunk in a jelly-like basic substance with rather small amount of cells.
Collagen gives a shelter to moistening gasket, to which the young skin is
obliged by its elasticity. Unfortunately, in the course of time the quantity of
collagen fibers decreases, and remaining fibers are not capable to store so much
moisture, as in young years. They continue to lose ability of swell-ing and
harden due to changes in composition of glycosaminoglycans (GAG). This process
can speed up external influences—free radicals, ozone, and a solar irradiation.
The third factor in the ageing process of the skin is decreasing ability of
regeneration of the upper layer. In the germinal layer, it is formed ever less
than young cells - accordingly ever less horn cells it is postponed on the skin
surface. Ageing of the skin apparently not only on small wrinkles.
Simultaneously with it change both contours of the person, and elasticity of the
skin. On the basis of reduction of a reserve of humidity pressure in tissues (turgor)
de-creases, and the surface of the skin falls down a little. Decreasing elastic
energy in muscles and elastic fibers is expressed that is more a than tissue,
than earlier, are subject to action of force of gravitation and droop downwards
is, becomes apparent first of all on the neck and cheeks.
The risk factors accelerating process of ageing of the skin, excessive reception
of alcohol, coffee, smok-ing, influence of ultraviolet rays and environmental
are.
Cosmetics of the biogenic nature enables to reduce sharply influence of
unfavourable factors on the skin, and in some cases practically completely them
to exclude. Creams of a series concern to such agents of new generation Plazan.
