Yes, I think a small reduction/lift would be ideal.   I recommend an in-office examination as well as a detailed discussion with a surgeon who you are comfortable with.   Finally, make sure your surgeon is a Double-Board Certified Plastic Surgeon certified by the American Board of Plastic Surgery (ABPS), a member of the American Society of Plastic Surgery (ASPS), a member of the American Society of Aesthetic Plastic Surgery (ASAPS), and a fellow of the American College of Surgeons (FACS).Best,Dr. DesaiBeverly Hills Institute for Aesthetic Plastic SurgeryHarvard Educated, Beverly Hills & Miami Beach TrainedDouble Board-Certified, Double Fellowship-Trained Beverly Hills Plastic Surgeon

Dear Brianna8888,it is hard to tell for sure without an examination, but based on your photos, you look like a good candidate for a breast lift. 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. I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.Daniel Barrett, MD, MHA, MS
