Skin aging is not a unique phenomenon but it is commonly divided into two different processes: chronological aging and photo-aging. Chronological aging represents the structural, functional and metabolic changes in the skin and degenerative changes in other body organs. Photo-aging is a consequence of oxidative damage due to overexposure to ultraviolet (UV) sunlight - both UVA and UVB (responsible for sunburn and basal and squamous cell carcinoma). Conditions of variable UV exposure may result from different latitudes, alteration of atmosphere, job, different behaviour to sun bathing. The deceleration of mortality rate is one of the most intriguing recent findings in longevity research.
