My breast is saggy and grows downwards. My areolas are also huge and I want them small

In person exam is essential as well as submitting a good set of photos. Based on limited photos- it appears that you may benefit from a mastopexy/lift- to make your breasts perky and areaolas smaller.
I suggest that you seek an experienced Board Certified PS

Thanks for your question. From your pictures, you seem to be a good candidate for a breast lift. A breast lift can help correct ptosis or breast droop as well as reduce the size of your areola. I recommend you schedule a consult for a proper evaluation, Please always consult with a board certified plastic surgeon. Take care, Moises Salama MD, Board Certified Plastic Surgeon
