Sorry for the delayed answer!
You should definitely add a 1.5 mm dermastamp to your 1.5 mm dermarolling sessions. During the same session, first stamp the scars, and then roll the area with the scars. Use it on your "pen scar" as well.
You do not have to treat both cheeks at the same time. Treat thoroughly one cheek, when it heals treat the other.
You could try our Tretinoin cream for your hyperpigmentation marks.
1. Since Infadolan is oily and contains vitamin A, should I stay away from it since I have acne prone
skin and my skin vitamin contains vit A already? If it's okay, should I only apply very little and use it on that day of the process only?
If you are acne prone, keep the treated area moisturized with something that you know from your experience does not break you out.
2. Should I avoid using my clindamycin/Benz per. Gel on the days I use vit. C?
Apply benzoyl peroxide in the morning but preferably not in the evening of vit. C application (vit. C should be applied in the evening). Vit. C application three times a week is sufficient.
Do not apply bezoyl peroxide in the evening of your needling day and preferably not the day after either.
3. Is it safe to wash my face with my all natural face wash right before dermarolling?
You can but it is not a replacement for disinfection.
4. When is it safe to exfoliate and/or mask my skin, since I will be dermarolling once a month?
If the skin is still red, swollen, tender or dry from microneedling, do not exfoliate. If you get scabs after stamping, do not exfoliate until the scabs fall off naturally by themselves.
5. What if the vitamin c makes my skin breakout? What should I do or use instead?
If it caused any problems then make it less concentrated: Dilute it with more water.
