Should I dress or let my wound air after breast reduction op.? (photos)

Thank you for your question and these types of wounds do occur on occasion.  It is hard to tell if you have an infection or not but this will require extensive wound care for several weeks and it is beyond the scope of this forum to discuss this here.  You will need to see your surgeon and arrange for daily wound care or go to a wound care clinic.  This will heal but it will take time and patience and it usually looks worse than it will after if heals.  I recommend that you not let it "dry out" but you keep it moist and clean which will allow it to heal faster.
