Do you think it is possible to change from 390 UHP to 330 HP, without a lift, adjusting the pocket?

Dear Marym9,
determining whether you need simply a breast augmentation versus a breast lift can be somewhat complicated. It depends on a number of factors including skin laxity and current nipple position. Generally speaking, if the nipples are lower than the inframammary line the patient will most likely need a breast lift. If the nipples are at or above the inframammary line we can generally get by with just a breast augmentation depending on the size of the implant the patient wants. I often still using implant when I perform a breast lift because it provides more upper breast fullness after the lift. To be sure a consultation with a board-certified plastic surgeon will help determine what the patient actually needs.

I would need to specific  measurements but it does appear you need a lift along with the implants. Your left side drops significantly. The capsule in the other side is holding the breast up to some degree making it appear higher up.
