Can I get a bbl when I'm 15 years old?

Hello dear!
Thanks for the question and provided information as well.
You should be at least 18 years old to be a candidate for plastic surgery.
In general, you need to be physically healthy and at a stable weight, have realistic expectations, be a non-smoker and your BMI needs to be 30 or less.
l recommend you to make an appointment with a board certified plastic surgeon to talk about your goals and anything you need to know.
Good luck :)

I will try to not be unkind with my response, but you must surely understand that ANY plastic surgeon's opinion after nearly 30 years of education will be much more important that that of a 15 year old patient that has not reached full adult growth, cannot understand the concept of "informed consent," and would accept surgery from a doctor unethical enough to proceed because a minor patient "just wants to get one."Please finish your growth, your education, and learn to write and speak in proper sentences with good grammar and spelling; then get a job with which you can earn the money to pay for elective surgery. These things will serve you much better than a bigger butt--honest! Best wishes! Dr. Tholen

Thank you for your question, Since you are under age you need your parents consent and they will need to be with you in all Doctors appointments since you are not able to sign legal consents for the procedure on your own. Most board certified plastic surgeons will advice you to wait a couple of years until your body has fully developed into adulthood.
