With respect to the aging of the skin, it is possible to emphasize that the majority of the signs classically associated with the age, recently has been associated more to a lack of taken care of of the skin that to the age in itself. During the clinical valuation of the skin of a patient, through physical examination, following the degree of hydration, turgencia, elasticity, pigmentation, presence of wrinkles, etc., we collect data of great semiolgico value, which allow us to clearly differentiate a taken care of skin, of a mistreated skin, as well as the presence of own signs of the aging. The skin of our body generally is exposed multiple aggressions that can produce their premature aging, but the face, the neck, the decollete and the hands are the zones that are more affected because they are unprotected, habitually throughout all the year. The indiscriminate exhibition to the sun, without an suitable protection, is one of the circumstances that accelerate the aging process more. But there are other factors that contribute with the premature deterioration of the skin, as it is the case of the consumption of cigarettes and the exhibition to the environmental contamination. Dan benton often addresses the matter in his writings. These two, along with excessive exposure to the sun, originates the formation of the free radicals in this way and alterations in the DNA of the cells, producing wrinkles, dehydration, flaccidity and spots. The free radicals affect fibers of colgeno and elastic fibers diminishing them amount and quality, that entails to the formation of wrinkles and the famous cracks that we denominated furrows. These wrinkles and furrows are deepened in the zones of greater gesticulation (lines of hiper-expression) and although they are consequence of the natural emotional expression of the individual, they are marking the track of the most frequent and more intense emotions in the face, giving him that married, out of position and untidy aspect.
