Day and Night Routine help

Hello!

I turn 30 next month and have noticed my skin changing, I used to have very oily skin but now my skin almost seems dehydrated but still oily around my nose and I am now more prone to spots, particularly around my jaw line. My pores seemed to have also doubled in size the last few months. Just wondering if anyone has products/routines they would recommend for day and night? Im in the UK so preferably products I can get here.

Any help/advice is appreciated!
