I’m confused about my options beyond basics (e.g., silicone, size,etc.).I want to minimize wrinkling and potential movement or asymmetry. I want to maximize upper pole fullness and to have the most natural looking and feeling breasts possible. My surgeon is suggesting Natrelle Inspira Cohesive. Are these too firm? My mom has very firm implants post mastectomy. I would like mine to be as soft as possible while fitting the other criteria. Any thoughts on these or suggestions on other types?
