Brown spot on cheek after AHA 70% peel. (photo)

2 weeks ago I used AHA 70% on a small brown spot on my cheek. It burned pretty bad so I neutralized it and washed off. It was red and irritated for a while and now it looks like it left a brown spot. This pic is exactly 2 weeks after. What is the best way to get this to fade quickly? I have access to Hydroquinone 4% and Retin A cream .1%. Immediately after the treatment I used Aquaphor every day. Or should I just do nothing. Please help? Thanks
