Is there anyone who doesn't respond well to Vitamin C ampoules?

I tried using it because I heard it was good for whitening, but when I used only the Vitamin C ampoule, blackheads formed too quickly. They formed fast, a lot, and felt sticky....

Is anyone else experiencing this? I've tried buying and using various products, but the result is the same. It doesn't seem to suit me, and I'm curious why.
