I definitely do not think it is a good idea to wear a compression sleeve as you will be suffocating the wound. I've never heard of anyone using preparation H for a tattoo.. You can get aquaphor over the counter at london drugs. Its not even at the pharmacy, its in the lotion isle. I would go with what the artists tells you as they are more knowledgeable about tattoos than a pharmacist is, but if you want to have the ointments ready beforehand then I strongly recommend aquaphor. It works great.
