[Routine help]Something is breaking me out

I used to be a very minimal skincare person, but I've been gradually using more products to really achieve that glass skin and prevent wrinkles. I've recently added the oil cleanser before my normal cleanser, as well as a vitamin C serum. I have heard that purging can be normal, and I have a feeling it is the Vitamin C serum. What are your thoughts? Also, should I switch from applying it every day to every other day?
