There is something bugging me for last few days. My nightly routine includes multiple products. I am using skinceuticlas CE Ferulic and Avon Anew Ultimate Night cream and once in a while Avon Nightly Nutrient Peel.
So what I am worried about is that if there are ingredients in any of the product that might inhibit working of the other.

For example I know that you cannot use Olay regenerist serum and Avon anew ultimate cream. Because nicinamide inhibits effectiveness of Prosirtuin. Does anyone have any idea?

I am including the ingredients list for two items. Couldn't find the third one.
