My navel is infected after tummy tuck. What should I use to heal my stomach? (Photo)

Thank you for your pictures.  This looks like a contact dermatitis (rash or reaction) more than an infection. Please have your plastic surgeon re-evaluate this area for diagnosis and treatment.

Thank you for your question and photograph.  It is difficult to see the incision line around your belly button to know what may be taking place, but if your surgeon feels that your belly button is infected, this often requires a course of antibiotics and local wound care.  This can involve simply applying a clean gauze to the belly button to keep things dry, placement of an antibiotic ointment, or occasionally wound packing.  Your surgeon is in the best position to help you heal, and I would recommend you keep an open line of communication with them about changes in the appearance of your belly button so that they can make the appropriate care recommendations.  

it could already be healed.  If there are still raw spots and draining areas, I would continue with petroleum jelly products such as Aqua-phor, Vaseline, CU-3 ointments etc and avoid antibiotics as your skin appears irritated and could benefit from avoiding antibiotics.
