Salicylic Acid Peel After Effects. When Can I Expect This Reaction to Completely Heal?

I had Salicylic Acid Peel on face at home 3 Weeks back. Except for the chin area, skin on face looks great. I had 1-2 Acne on chin before I applied it. I got bad reaction after the peel and had chin full of Acne - I am not sure if they are cysts or cold sore. I had to visit doctor because I had fever and I thought the cause was my throat infection. Prescribed me erythromycin which I apply twice a day on affected area. The size is reduced but o would like to know when can it go away totally.
