125lb, 5’4”. Changing implants from 290cc to 190cc. Will this equal less animation deformity and less palpable implants?

Animation deformity is related to the detachment of the muscle that is done with the dual plane procedure. It can be corrected by converting to the split muscle plane, which will maintain muscle coverage over the upper part of the implant. You would lose coverage in the middle, but usually it is on the sides and bottom where the implants are palpable. Another thing to consider would be to change to a more cohesive implant such as Sientra or Allergan Soft Touch. Downsizing may result in a more deflated look with looser skin.

I don't like the term "animation deformity" because the reality is that it is a phenomenon that is logically anticipated as a consequence of lifting the muscle. The dual plane approach usually means the upper part of the implant is covered by the muscle but the lower part hangs into the lower portion of the breast curvature for a more natural and softer result. However, if you feel your size is too large, reducing somewhat may help you feel more comfortable with the overall appearance. Fixing the animation issue often requires switching to a subglandular position, which carries a higher risk of capsular contracture. If you have enough tissue to cover in a fully subglandular position, that might be a consideration worth discussing with a surgeon. The tradeoff is basically between palpability/rippling/coverage concerns vs. animation phenomenon.As others have stated, at least one of your pictures looks like one breast pocket may be slightly higher than the other which may be indicative of a capsular contracture and you should discuss this with the surgeon(s) with whom you consult in order to examine this thoroughly and address whether a capsule procedure (capsulectomy typically) is necessary.
