Will Silicone Implants for Breast Reconstruction Soften over Time?

They should soften over time but it also depends on what is causing it. It could just be overlying inflammation and swelling causing it to feel taught. Usually if the implant is subpectoral then it will take time for the muscle to stretch more and soften around the implant. In my experience, this is the most common cause. Also, there could be capsular contracture which will not improve on its own but requires intervention. Usually Singular or Accolade is enough, but some people will add in milk thistle.

Give your reconstruction some time to settle.  In general there should be some softness to the reconstruction and some movement to the implant especially if the pocket was made a bit larger than the implant.  As time goes by the area will soften and the implant may have more movement.

In general I like to place a smaller implant in relation the pocket that has been created by the tissue expander so that the implant feels soft and moves around.

It is difficult to say what your issue is without and exam, but it could be that there is some inflammation that makes them feel hard at this point.

Hope that helps.
