Hello everyone I'm new to this so I have no idea if I'm in the right topic (Opps), well either ways I'm gonna continue.. well I'm 15 years old and really hating my acne and scared it could stay there forever and want to ask you guys for help.. so I was wondering if these are acne marks or scars, I've been googling images but they both show scars (so I think!) but either ways can you guys help me out with things that can make it look better.. should I see a dermatologist? Get a derma pen or roller? I have no idea  Help me out! Thanks

EDIT: Also I never really picked at my acne while it was active but I do have really oily skin! I'm also in sports so I do sweat quite a lot.
