How long until after getting a BBL can you get a tattoo?

Dear Jas.xo,
every plastic surgeon has his own postoperative protocol which he recommends to his patients. I would suggest you to discuss this with your plastic surgeon.

At six weeks patients typically see results that are about 75% final. At that point it’s also going to be highly unlikely that any physical manipulation changes the outcome.
A couple of months should be just fine.
