Different color liquid for drains after Sientra breast augmentation. Am I using my right side too much? (Photo)

There is no need to be alarmed by the difference in drainage color and output demonstrated by your photos.  These variances are completely normal.

For breast augmentation, I typically do not use drains and patients can go back to working or working out after 48 hours.  When drains are used, it is very common to have one side with a straw colored fluid called serous fluid and another with a red tinge.  Yours appears entirely normal and has nothing to do with the type of implant.
