Is this amount of scabbing normal three weeks after a breast reduction? (Photos)

Congratulations on having undergone the breast reduction procedure; this operation tends to be one of the most patient pleasing operations we perform. It is not unusual for one side to heal differently than the other. Likewise, some "scabbing" is not unusual.  It is possible, that once the scabs lift off, that the appearance of the incision lines will look worse (for example yellowish drainage), before they look better.  In my experience, the scabs should be lifted and healing much further along by the time you are at the 2 month post op mark. It is always good to communicate your concerns/questions directly with your plastic surgeon;  he/she  may want to see you earlier that already scheduled (based on your photographs, I do not think there is any urgency). Best wishes for an outcome that you will be pleased with longer-term.

Appears as acceptable hearing process is occurring. But best to to be seen by your chosen surgeon this coming week.

Scabbing can occur, even if it is on one breast and not the other. One breast tends to heal differently than the other. Especially if there is a lot more removed on one. I don't see anything that requires an urgent appointment. I would simply communicate your scabs to your surgeon and ask them what treatment they would like you to use. Every surgeon is a bit different on this. You can expect this to heal with good long-term results. It will just take a little longer on this side. Congratulations on having a reduction!
