My left side implant isn't moving as down like the right side. Is this normal?

Implants can take up to 2 months to completely "fall."  During that time period one implant is often lower than the other.  Ultimately, the two implants are at the same level/position once the descent is complete.  Not sure how recently your surgery was but I assume not too long ago.  Best of luck!

It is very common for one implant to drop before the other implant drops into position.  I advise my patient that this process can take 3- 4 months and sometimes longer.  You did not give the date of your surgery but my advice to you would be to give them at least 6 months to settle before becoming concerned.  As always, consult your own plastic surgeon if you have concerns.

Implants often descend into their final positions at slightly different rates. And it often takes 3 or more months for the implants to reach their final position and shape. You might not have anything to worry about. But you might have an early capsular contracture on the left side or the left side pocket might be dissected differently than the right. If either of these situations is the case, you might be need to have something done to correct the asymmetry. It is best to discuss your concerns with your surgeon.
