How to get rid of this dark spot?

[Chris1221 0]

So about 6 months ago I squeezed a headless pimple on my cheek too hard and it became red and started bleeding. Ever since then there has been a red outlined mark, it's not bumpy or anything it's just annoying. Is there any way to remove it effectively?
