Lipo and BBL. I’m 5’8 and weight 170. Is 500cc enough to see a difference in my body? (photos)

500 cc is  not very much in most cases.  Based upon your BMI, you may have enough fat for over 500cc per buttock.  Remember that on the average, 1/2 of the transferred fat lives.
The final shape of the buttocks is largely determined by the starting anatomy, the distensibility of the tissues injected, and the surgical skill employed by the plastic surgeon. Significant volume can be added to the buttocks, producing much larger, more projected buttocks. The fat is expertly placed to produce very shapely, custom tailored buttocks.  Even large defects in the buttocks or marked asymmetry can be remedied with this fat transfer technique.
Certain aspects of the buttocks or hips may not be improved as much if the tissues do not allow for much stretch or cannot accommodate the fat that is transferred. In these cases, the final result will be limited by the skin envelope. This is an issue that cannot be completely controlled by the surgeon. Finally, the ability of some patients to heal and retain more of the fat than another patient accounts for differences in shape and results following BBL.
Consult via Skype or email with a board certified PS who is an expert in lipo and BBLs, and has hundreds of before and after photos on his/her website along with favorable patient reviews.

Thank you for your question. Unfortunately, the photos you posted are hiding the areas you are asking about. Need to post photos without clothing which hide and compress these areas. Liposuction and a BBL is a technical and artistic operation. It is as important to sculpt the torso as the enhancement and shaping of the buttocks. I can "guesstimate" the amount of fat transfer into the buttocks, but the actual volume depends on the skin laxity, thickness of the subcutaneous fat layer (fat between the skin and the muscle fascia), fibrous bands in the fat and distensibility of the fat compartment. Of the little areas that are exposed in your photos, you have enough fat that can give you an hourglass figure.See a board certified plastic surgeon experienced in advanced body sculpting techniques for an in person consultation/evaluation. Good luck. 

Dear Maya0589,
based on your photos, you look like a good candidate for a BBL. Liposuction of your abdomen, back and flanks should give you more curves and hourglass shape and fat transfer to buttocks should give you more projection. I would suggest you to consult a board-certified plastic surgeon because only after a thorough examination you will get more information and recommendations.
