4th revision - Best surgical approach to fix waterfall effect, scarring and asymmetry? (photo)

Hello everyone! I’ve been struggling with my breasts for 9 years, and I would truly appreciate your insights! I’m a 28-year-old healthy woman, but my self-esteem has taken a huge hit due to repeated surgeries with disappointing results. I had severe ptosis my entire life, so in 2016, I underwent a mastopexy with subglandular implants. Soon after, my left breast started to look boxy, so my surgeon performed a revision in 2017, lowering both nipples to improve proportions—but only by reducing the skin, not adjusting the implant pocket. A year later, my left breast still looked boxy and lacked an underboob curve, so I had another mastopexy. Over time, my left breast started to lose its shape again, and I finally realized I had been experiencing bottoming out this entire time. In 2022, my surgeon performed yet another mastopexy, this time moving my implants from over the muscle to under the muscle. Unfortunately, the results are worse than ever: Neither breast has a proper underboob curve, they don't look natural, my right breast looks too high, I have a waterfall effect and double scars. I am now considering a 4th revision with a new surgeon, but I want to make the most informed decision possible. What would be the best surgical approach to fix this? Can I replace the implant back to subglandular position? Has anyone had success correcting a case like mine? Any advice would mean the world to me. Thank you so much for your time and expertise!
