Summary
One of the important adverse effects induced by certain harmful environmental factors in humans body seems to be skin photoaging. This process is influenced by the free radicals, formed by solar radiation. However, human’s body possess limited capacity for free radicals destruction or inactivation. In order to support the protective action of the human body the antioxidants are applied. They can be either of natural or synthetic origin. The fruits seems to be one of the important source of natural antioxidants. This group of substances could be applied in order to prevent heart, hematological as well as the central and peripheral nervous system disorders, in alleviating the symptoms of menopause, allergy etc. Antioxidants could also modulate diverse biochemical processes involved in carcinogenesis. Moreover, they may exert their inhibitory effect on skin photoaging. Therefore, these compounds are increasingly applied to produce cosmetic formulations. Antioxidants reduce the harmful effect of ultraviolet radiation on the skin. Their mechanism of action is based on scavenging and counteracting of free radicals, thus preventing oxidative damage. Therefore, these compounds are considered to be complementary to physical and chemical UV filters. Humans ingest a lot of antioxidants as food constituents. One of the most rich sources seems to be fruits, particularly those containing anthocyans i.e. flavonoid’s dyes. Their antioxidant action is due to the activity of flavonoids and ascorbic acid. The following fruits should be taken into account: black chokeberry, grapes and some berries, i.e. bilberries, blueberries, also blackcurrants as well as citrus fruits.
