My friend told me that the grapenol 30 mg capsules are made of grapes and can be used for skin rejuvenation. When I opened the website of grapenol I found that it I s made of grapes extract but nothing was mentioned about its use. I kept searching but till now I am not sure about its use. It will be very great if anyone over this forum can tell me what it is used for. Can I use it for the rejuvenation of my skin?
