HELP! Sore, red, flaky skin... with congested spots

[RobertDeNiro]

My skin is usually oily but in the last few weeks it has become flaky dry and sore. With some congested pores and a few spots. My skin is extremely sensitive but this is a new level.
Please help, what can I try?

Go to a dermatologist.

A proper one, fully fledged consultant doctor.

It is much cheaper in the long-term than buying lots of products.

In the mean time, be gentle - something like Cerave cleanser and moisturizer.
