I'm 5'7 and I weigh roughly 180 lbs. If I get a BBL, will I have extra skin and look flabby? (Photo)

Based on your photos it appears that you are an excellent candidate for a brazilian butt lift.  It does not appear that you have a significant amount of skin laxity.  Consider an in person consultation for a more definitive answer.  Best wishes.

You appear to be a good candidate for liposuction of the abdomen, sides, back and Brazilian buttlift.  I
would search for the board certified plastic surgeon who you feel is
most likely to give you the best results and who performs hundreds of
these procedures each year. I would look at patient reviews as well as
before and after photos on that surgeon's website.Kenneth Hughes, MDLos Angeles, CA

Hello dear!
Thanks for the pictures and provided information as well.
Based on your photos, you are a great candidate for liposuction with a BBL and a tummy tuck, to give you a nice tight tummy and to get rid of the extra skin, and I think you'll get very good results.
Liposuction allows your plastic surgeon to transform your entire shape. You can improve your waist, back and flanks, and of course your buttock, to give you a beautiful heart shape, along with the tummy tuck.
In general, you need to be physically healthy and at a stable weight, have realistic expectations, be a non-smoker and your BMI needs to be 30 or less.
l recommend you to make an appointment with a board certified plastic surgeon to talk about your goals and anything you need to know.
Good luck :)

You many be an excellent candidate for a BBL but you would need to be seen in person to evaluate the quality of your tissues. Best of luck.

Your photos suggest that you would be a good candidate for the BBL and liposuction of the abdomen and waist. But you need to be examined to be certain. You should counsult with a Board Certified PS with extensive experience perfoming the BBL. Good luck!
