How long after a BBL can I get a tattoo on my buttocks?

Thanks for your question. It depends on how the buttocks is healing, but usually around 3 to 6 months it should be ok. Please always consult with a board certified plastic surgeon.
Take care,

 Thank you very much for this interesting question. I am sure there is no available data to back up my answer with science. I would advise you to leave your skin alone for about three months. But as I said before to my knowledge there has never been any research on this problem. Have a wonderful rest of the day and greetings from the beautiful island of Jamaica.

Hello
Follow your PS instructions after the BBL, once the healing has resumed, usually between 4 to 6 months you can ask your doctor the best time to get the tattoo.
Each patient is different and the healing period may vary.
