Collecting and using grape extract as a colorant in cosmetic products

The paper presents the results of studies on the extraction of biologically active substances, the flavonoids primarily, from grapes Vitis Vinifera Isabella. The researchers have studied the biochemical composition of whole grapes, as well as their parts (peel, pulp, bone) and have shown that the most amount of flavonoids are found in grape seeds, while most coloring agents are contained in the peel. To be competitive, modern cosmetic products should provide a quick visible effect, be attractive, but also contain preferably natural biologically active substances, which stimulate metabolism and reparative functions of the human skin.
