I got a severe bacon grease burn on my left breast, how is the best way to treat the burn to prevent scarring and infection?

See Plastic surgeon: Grease burns are usually deep. These burns are best treated by prescription topical antibiotic medication. See your primary care or your local plastic surgeon. If you have an infection already then it may convert even a mid dermal burn injury to a deeper injury. The infection will likely need treatment with antibiotics by mouth.
