7 weeks post tummy tuck, lipo and BBL. Is it too late to start wearing my back board to form that dent in my lower back? (Photo)

Thank you for your question and photo. Yes it is too late now. Although back boards or foams do not create the dent you are looking for, I use double foam pads I customize for the patient right after surgery. It is important to adequately sculpt the lower back, by removing the lower back fat pad. The space created between the skin and the backbone and paraspinous muscles if not compressed to "stick" and heal together, will accumulate fluid, more scarring and poor shape. You are too late to recreate this dent at this stage of the healing. It is also possible that your surgeon did not remove all the fat in this area. Wait until you are healed and be reevaluated. Good luck with healing.

Thank you for sharing your question and photograph and congratulations on your procedures.  The low back indentation is created at the time of surgery, based on your anatomy, rather than the use of a compression garment or foam board.  I would continue to allow your results time to mature and reevaluate your outcome 6+ months after surgery to assess if a small revision could be performed.  Hope this helps.

External devices do not create permanent contour changes such as a dent in your lower back. The best person to ask would be your surgeon.
