Publisher Summary Skin aging may be caused by internal and external causes, defining internal aging as the natural physiological process, and external aging as a host of conditions (sunlight, pollution, smoke, dietary habits) capable of mimicking the effect of physiological aging. Furthermore, as we grow old, we become gradually sensitized to external skin damage by the dwindling healing properties of our organism. For this reason, research of antiaging products is currently hotly pursued at genomic, pharmacological, and cosmetic levels. Recent studies also suggest a correlation between the intake of olives and olive oil and skin wrinkling, as well as a link between dietary nutrient intake and skin-aging appearance. A diet rich in fruits and vegetables with olives and olive oil as the major source of fats is considered an important protection against the main diseases associated with oxidative stress. Olive derivatives (fruits, olive oil, and olive leaves) are very rich in antioxidant compounds. Polyphenols like oleuropein (in the leaves), verbascoside (in the fruit), and tyrosol and hydroxytyrosol (in all olive foodstuffs) may exert an interesting antioxidant activity in various districts of the organism, including the skin. Various extracts have been developed in order to provide olive-based antioxidant products as dietary ingredients. Unsurprisingly, olive oil has become a very active area of multidisciplinary research. |
