[Acne] redness and spots help

The skin on my cheeks has always been clear with nothing but washing with soap once a day. A year ago it started getting dry so I used moisturiser occasionally. It gradually got worse and now it’s red and covered in small red spots and tiny whiteheads, and feels very rough.

I use soap to wash and then moisturiser after (tried about 5 different brands- some seem slightly worse than others but not much in it).

What should I do? Change products/routine? See a pharmacist? Or a GP? (I’m in UK)

Any recommendations appreciated thanks!
