If you´re using a moisturizer apply it after the CP serum rather than mixing it together. I have never heard anything about waiting 20 minutes or copper peptides effectiveness being affected in a negative way..(.-except that they should not be used with vitamin C products)... this is new to me.
If you´re trying to get rid off scars have you checked out the Trireduction stuff yet? It´s specially designed for things like scars. I also recommend following the instruction and suggestions for using the products including the CP serum, it´s pretty helpful.

I´ve not gotten the Super cop stuff yet what´s it like?
