Indian ink tattoo HELP!?

basicly thought itcwould be clever to get a tattoo, i got it with a blade from a sharpener and indian ink, i have tryed to pick out the ink with a needle from the wound and it didnt wok well, however, it doesnt look that deep, i only got it done a few hours ago, is there anyway of removing it at home, if the army see it when i join up (16) will they not allow me to join because of it, thanks :)
