I'm obviously not an expert my any means but in my opinion I believe because you are fairly darker you may have some hyperpigmentation and a few indented scars there, not many though which is always a plus! But, what I would recommend is to wear a sunscreen with SPF 50 in to help keep your skin protected from the sun and I mean damn well protected, the sun is evil when it comes to discolouration in the skin and if you want to begin exfoliating once a week that may help as well but just do it gently as you don't want to make anything worse! Perhaps try the baby brush method? It's a gentle method that helps exfoliate and I think there's a post on this website about it, maybe google it? Should come up but yeah, just keep it protected and don't touch it!

thatll all go away with time for sure theres no indentions there really
