Only time will make them go away. We can't say how long will it takes...it can takes a few weeks or a few years, it depends.
For sure, you MUST wear a sunscreen everydayotherwise it will takes much much longer for these red marks to go away (sun makes them worse)and a goodexfoliator might help. What AHA did you use? You may be allergic to that one so try another one.
Also try a BHA exfoliator....as an advice choose a good exfoliator and not the ones on the cheap side
Good luck!
I strongly suggest looking into exfoliating a little more especially one of good quality. I personally use the genius nightly exfoliating pads ({LINK REMOVED}) which are pH corrective and come in an instant active form preparing the skin for further products also. I can send you the whole fact sheet on the product if you would like
