It's so strange that You've developedt this reaction after using zorac for only 2 times.
I've been using it on and off for years and although I agree that its a very strong retinoid and Ive also had some side effects from it (weird rash all over my face,very sensitive and dry skin,etc),those side effects only appeared if I would prolong my treatment for longer than 6 months.
Can u tell me what does your skin look like right now and what products do you use?
And please don't worry,as a tazorac veteran (firstly used it in 2006) I can assure you that your skin will heal and get better.But unfortunetaly It takes time.
Oh and sorry for my english,I am polish,so eng isn't my first language;)
