Do I have an infection in the incisions of my areolar reduction? (photos)

I had an aereolar reduction 3 weeks ago. Everything seemed to be healing fine until a few days ago. Both my aereola and nipples became very itchy and started weeping a lot of puss. I've been using polysporin and covering with gauze but now they are looking much more red and irritated then a week ago. Is this an infection or normal healing?
