How to Even out Skin Texture and Color from Acne Scar?

I put benzoyl peroxide 10% on a pimple on my chin. It was so painful I even tried to pop it. The next day, the skin on my chin peeled off. It has been three months and I now have uneven my skin texture and a circle-shaped indent. Also, it's a little red. I have been using Remergent DNA Repair Serum on my whole face. How can I smooth out my skin? I need the skin texture to be normal and smooth again. Will it just go back to normal?
