I've been on the DKR for 7 weeks and I'm still getting breakouts. But the red marks are what I'm worried about. It makes my face look so much worse. Should I be waiting until my acne is totally clear before I start treating red marks? If I can start, what should I start treating them with? I'm not even really sure if these are red marks, that's just what it looks like to me. Take a look and let me know 
I treat my red-marks simultaneously with my "active" Acne. (with different treatments) However, if you have more Acne than marks and/or the same amount, I would wait for your Acne to disperse before treating your Red-marks.
The good news about red-marks is that they do fade. The bad news (at least in my case) is that they take a LONG time to do so. My red-marks have improved by about 30% in the past 1 1/2 months. The process I use is fairly simple:
If it is morning: I take a shower and let water gently run over my face for about five minutes. I then apply a light coat of Aloe-Vera based sunscreen. It is Oil-free. It also contains vitamins A,C,&E. I hear these are good for red-marks.
If it is night, I wash face with a Witch Hazel soaked cotton ball. I then apply a moderate coat of AHA (Alpha Hydroxy) and let the skin soak it up.
This is just the method that has given me the best results. If anyone has a better method, I would Love to hear it.
Walgreens has an 8% aha cream and there is an aha gel on here you can buy as well.
You can make your own vitamin c serum too!
I use fruit fresh because my mom does a lot of canning but you can buy vitamin c powder or capsules. I mix mine with pure glycerin but, you can mix the vitamin c with your moisturizer or water. I would just add a pinch to your moisturizer so its fresh every time.
Here is some information on vitamin c
