Please help! I have very sensitive skin with rosacea, texture and CC/blackhead issues. I suspect I have SD as well but I don't have a diagnosis. I haven't used anything on my face for months and it was looking pretty clear (minimal bumps and redness, a little flaky/dehydrated, but bearable)

Because I can't leave well enough alone, I started using micellar water every night (I use cotton pads and a lot of dirt comes off considering I don't wear makeup) hoping to gently exfoliate and a serum from Bioderma that was recommended for sensitive, dehydrated skin. I patch tested for a couple nights and got no immediate reaction. I used it on my whole face and it looked amazing at first! My skin looked smooth and hydrated on day 3.

On day 4, I woke up to my skin being extremely oily, enlarged pores, stinging sensation, and some sort of red mark on my cheek that was not there the day before. I'm not sure if this is from the micellar water or the serum but either way, what's my best course of action here? Should I just cut out both products and hope this spot on my face goes away on its own eventually? Thank you in advance for any help!
