This is just hyperpigmentation and not scars. Lactic acid has always helped me with red marks. Maybe try a lactic acid peel.

The two things that worked incredibly for my red marks are lemon juice straight from a lemon (put a little on your finger or a cotton ball and dab it on the red areas, I saw results in two days) and AHA+ from acne.org's store (also saw results in two days).

Am I missing something here - what scars?

Try rosehip oil. I haven't tried this myself, but my sister has told me lots about it. It will help with those red marks. But will not work overnight. I've heard this is comodegenic so don't use if you have any active spots.

Your skin is amazing and the marks will go with time.

Seriously. No hate on the OP, but this post is ridiculous. You have great skin.

I would recommend you to use natural manuka honey. Manuka UMF honey helps control a fungal and bacterial infections including acne, heals damaged skin and reduce scars.
