Aging causes slowing of metabolism and division of fibroblasts - skin cells responsible for the production of collagen and elastin fibers and reduction in production of the natural moisturizing factor (NMF). Connective tissue loses its strength, flexibility and ability to bind water which causes the formation of wrinkles (due to the rupture of delicate structure of the collagen and elastin fibers and dry skin). In turn, due to frequent unconscious muscle contraction, wrinkles with time worsen and become more prominent.
In the beginning, when you notice fine lines around the eyes, forehead, at the base of the nose and later, when as a result of repeated facial movements, wrinkles will be formed: furrows on the forehead and crow's feet. In adulthood, due to gravity and fall of hormone levels, wrinkles begin to develop across the forehead and neck, the skin is thinner and dry.
