Palmitic acid (%) 6.8Stearic acid (%) 1.5Oleic acid (%) 14.7Linoleic acid (%) 75.0Linolenic acid (%) 1.3 Effect:The major active constituents of grape seed oil are proanthocyanidins and up to over 70% of linoleic acid, which can resist free radicals, aging and help to absorb vitamin C and E, strengthen the vessel flexibility of circulation system, decrease ultraviolet harm,protect the skin collagen protein,resist venous engorgement and dropsy, prevent melanin pigementation.
