It looks like hyper-pigmentation to me, similar to what I have. I don't see any active acne which is good and they're not that red from the looks of it. I'm sure they'll fade nicely!

Are these marks completely flat and feel like normal skin ?

If yes : these are red marks from past acne, they will fade eventually

If you feel a bump : these are acne cysts, either they will go to the surface and be whiteheads or slowly fade. Once the acne is cured, the red mark will fade.

Try going the regimen or some topical wash if you didn't yet

Dude, I was in your position about a year ago and came to this site for advice and completely screwed up my face by listening to everybody...just go to a dermatologist and ask about it. do not accept internet advice...I ended up on accutane because of it!
