Advice for routine please!

I have combination skin and I feel like my routine is taking care of hydrating well but I’m left quite oily during the day around my t zone and nose area and I have enlarged pores and blackheads still.

I heard niacinamide could help this so I stared using the fenty beauty fat water as it only has 5% whereas the Ordinary 10% serum caused me to have redness and sensitivity.

I heard exfoliating also helps but I’m very new to it so i started by using the ole hendricksen PHAT mask because I heard PHA’s are less rough on the skin. However I’m thinking of using salycilic acid or paula’s choice BHA exfoliating toner. I didn’t have any sensibility with the mask but I feel like it’s not doing enough.

Do you have any recommendations for targeted treatments for my issue and overall how I could improve my routine ?

Thanks a lot
