Dinged the top of my Aluminum Macbook

Noticed a ding on the edge of the top. I have no idea how it got there. Its small but now its the only thing I see when I look at it.

What are my options?

I bought this laptop second hand still sealed in the box. The original owner received it as a gift but already had a pro.

It still has apple care on it.

Bring it in, either apple will fix it or not, couldn't hurt to try.
