Your photo suggests a significant chemical burn. I am not sure how or why you were treated with 80% TCA as this strength is not used for any of the peels that I am aware of. My STRONG recommendation is seek the immediate advice of a board certified Plastic, Facial Plastic or Dermatologist who has experience in treating chemical burns such as you have. On going care to prevent post inflammatory hyperpigmentation and scarring will be important. Follow there advice and care.
