I'm 23 with no children. Can I get a BBL?

There is no problem getting a BBL at your age with no children.  What is more important is how much fat you have available, the size/shape you are looking for and the type of skin you have.  

Age 23 is fine for a BBL.  You need make sure you have enough fat to use as donor graft for the butt augmentation.

Dear Ms. Love_light_lili,Thank you for your questions. Unfortunately without photos and a examination I can only advise you in general terms, however I hope you will find them helpful.The amount of fat injected depends on:1) the amount of fat harvested2) the amount of suitable fat that is abel to be purified3) the "stretchability" of your buttock skinOne can try to gain weight prior to the procedure in hope that the areas you gain weight can be liposuctioned.Caveat: not all weight gain can not be harvested (some may be deposited on your internal organs or areas that can't be liposuctioned).Please make several appointments with experienced Plastic Surgeons who listens to your specific desires and who are not only Certified by the American Board of Plastic Surgery but in addition ideally a member of the American Society for Aesthetic Plastic Surgery (denoting by membership as having met additional criteria and a focus on Cosmetic Plastic Surgery).My best wishes, Dr. R.
