Hi. This depends on where you place the grape. Some areas of your body will wrinkle faster than others. My advice on this thought, is don't get a green or red blob on your body just to say, all the way through, I'm waiting for it to turn into a grape. Besides, if you get it too big, it will be a plum. Then, as you age, you will be an old prune! Naw, not a good idea! Have a grape/plum free night and do think twice before getting permanent ink.
