Not sure about my serums

Hi, My skin doesn’t tolerate most vitamin c serums, but it handles the vanicream well, I want more antioxidants so I’m using the Inkey list Q10 serum. Does it make sense for me to layer both serums, or should I blend them in my hand, or should I just use one at a time and alternate days? I appreciate any thoughts you’d like to share, including suggestions for improving my routine. Thanks a lot.
