Would I be able to get a donut mastopexy or non-surgical lift? (Photos)

Looking at the photos, your nipple is positioned low and you have skin excess You can achieve a good result with a breast reduction surgery performed with an anchor scar.

You are a good candidate for a full, standard breast lift/reduction (basically the same procedure in your case). This will provide improved shape, lift and proportion. I would not hesitate to proceed. Thank you.

Hello, you have grade III breast ptosis, you need an inverted T breast lift, there is no non-surgical procedure that can improve the shape of your breasts or lift them.

Dear Powerful380781,
my preferred lift is a lollipop lift when a periareolar won't do (ie greater than 2cm lift required). The lollipop technique was created by a Canadian plastic surgeon named Elizabeth Hall-Findley and treats the breast as a three dimensional structure instead of two dimensions (anchor - lift). Most importantly it does not require the horizontal component scars that the anchor-lift requires and breasts appear much more natural, lifted, and less boxy. Lastly, the lift lasts longer because the lollipop doesn't rely on the skin to hold the breast up, its actually breast tissue thats being brought together to support the breast and hence improves longevity.

Your nipples are located below your breast fold and are pointing downward. A vertical breast lift would most likely be the most effective option for you, since a donut lift would provide only a minor improvement.
