Which procedure would keep me at the same size while helping me achieve a fuller, perkier look? (photos)

I had saline implants in 2010, removed them and had a lift in 2019. Since the last surgery, I’ve had a scar bulge under my left breast but lived with it. After weight loss, my breasts are no longer perky, with stretch marks and sagging. I want perkier breasts with some fullness but not larger, and I’d like to reduce scarring if possible. Unsure if I need another lift, implants, or options like fat transfer or laser. I expect surgery but want to hear all options, including less invasive ones. :)
