RESUMEN
The skin is regarded as the largest organ in our system and has the general purposes of physical, mechanical and immunological protection, sealing against the elements and thermoregulation and tactile perception of environmental stimuli. Skin aging is a complex biological event that affects all skin layers. The dermis, however, is particularly affected due to its histophysiologies' characteristics. With the expansion of life expectancy, the dermatological questions among the older population has had an increasingly bigger importance, propelling the development and perfecting of rejuvenation techniques. The phenol peeling is a deep, chemical one, which offers intense clinical results. The application on small areas of the body, for example, around the eyes, is safe and does not lead to cardiovascular complications. This review aims to update the knowledge of skin histology, the alterations related to photoaging and phenol peeling.
