Huge Scar After Chemical Peel

I have dealt with acne since I was a teenager. One of my friends interested me in the chemical peel process. After the chemical peel, I was told to use a light soap (Aveeno) and follow up two times a day with a product named New Skin. Once, I noticed the right cheek mostly healed and the left cheek seemed to have this huge scar. I went back to the school and was told the whole peel process went wrong and to start using the product I'm still using today (Mederma). Is there anything I can do to restore my skin?
