Sunscreen composition

#This invention relates to skin care compositions and treatments which contain activated platelet factors, more particularly to such compositions and treatments which contain platelet derived growth factor.

#A broad range of liquids, creams, lotions, emulsions, oils, gels, etc. have been used for topical application to the skin to protect the skin from various elements or conditions such as the sun, wind, cold and dryness or to treat the skin after it has been subjected to such elements or conditions, or after it has been cut or abraded. These products covering a wide range of cosmetics are generally used to help maintain the skin in its normal condition, to aid in restoring it to its normal condition, or to improve the visual appearance of the skin. The skin conditions addressed by cosmetics and treatment compositions are too numerous to mention.

#Activated platelet factors such as platelet derived growth factor have been shown to be useful wound healing substances. Knighton in International Patent Publication Number WO86/03122 teaches the preparation of platelet-drived growth factor (PDGF) and platelet-derived angiogenesis factor (ADAF) by the activation of platelet-rich plasma from whole blood with thrombin. These activated factors are then applied to a non-healing wound in a medicated salve.
