Hi, I have a tattoo on my upper left arm (~5-6" length & width) in black ink. I went for six sessions of laser tattoo removal which left me with hypopigmentation (I'm dark-skinned) and the ink still visible, albeit faded. What would be the next best option? I have been looking into skin grafting. Thanks in advance! I just want this thing removed for good. I'm prepared for a scar, because I'm going to have one either way.
