Will cocoa butter help in masking of stretch marks please explain?

Not if they're there. Cocoa butter can help moisturize the skin and reduce the chances of developing stretch marks. If you have already developed stretch marks the cocoa butter may not help them fade. Body contour cream can help them fade http://link.videoplatform.limelight.com/media/?mediaId=cb17b01acc8b498d9e6ed4434ab37cc6&width=480&height=321&playerForm=Player.
