Is my Skin Elastic Enough for Liposuction?

patients of your age group typically find that the skin redrapes well after liposuction. Stretchmarks won't change. Other areas might gain more fat after liposuction if the amount of calories taken in during the day doesn't change compared to the amount before liposuction, and yes it is possible that one or the only area in which this may happen is your breasts, but it is unpredictable.

Looking at your photos is not quite the same as an in person examination. However, you should do great with a liposuction. Do not let anyone talk you into a tummy tuck. This places a horrible scar across the abdomen. Trust me it does not hide when you are not wearing clothing. Liposuction is your best bet. The fact that you have lost so much weight and don't have hanging skin means that you are likely to do just fine with liposuction.
Regarding the breasts, you may benefit from a breast lift that includes an appropriately sized implant. Recognize that this combination of surgeries is common but it does increase the risk of surgery slightly compared to having these procedures done separately. For the liposuction you need consider seeing a dermatologic surgeon who can perform this liposuction under local anesthesia using tumescent liposuction. The breast surgery should be performed by a board certified general plastic surgeon.
Be certain that the surgeon spends enough time with you that you are certain he or she understands what you are trying to accomplish with the surgery. Because you are young, it is a very good idea to bring someone with you to the consultation like your mother or a good friend who can help you stay on track with the surgeon during the consultation. Avoid being star struck by the surgeon. They are human and your time and desires are just as important as their time and interests.
