Tkanks for Your advice 
JBForrester, i use Retin-A and Epiduo because i have acne (recurrence after laser treatment) so i'd rather not stop using these products.
I take vitamin C, Cat's Claw Extract, Green Tea Extract, Astragaloside IV, zinc.
Is it worth to buy supplements contains AC-11 ?
Regards
You're welcome :-) That's fine about the Retin-A. Glad you're taking Vitamin C. I don't know much about AC-11. If you haven't found any long- or short-term negative side effects stated in any published studies, than I think it wouldn't hurt you to take it. Another thing I would take daily is baby aspirin, 81mg. There have been
numerous amounts of studies on this that have proven to prevent certain types of cancers due to it's anti-inflammatory effects on the body. It could possibly reduce any inflammation that occurred with your laser as well. What kind of damage occurred with the laser by the way?
