How soon can I exchange implants for larger size? hoping to go from 330 moderate to 415 full profile

Dear Witty650946,
generally speaking it is possible to exchange implants shortly after initial surgery, but most surgeons would recommend you wait to see the final results of your surgery. If you are considering surgery, I would suggest you consult a board-certified plastic surgeon. Only after a thorough examination, you will get more information and recommendations.

It has been enough time to let your tissue heal. You can increase, but make sure the additional weight will not be too heavy for your frame or tissue.

If you are certain about your decision to exchange implants and you have been healing normally it is fine for you to proceed at any time. Visit with your board certified plastic surgeon to discuss your concerns and schedule your procedure.
