[routine help] questions about routine

Hi! I’ve been using the same routine for the past 5 years or so. I’ve noticed a lot of little white pimples(?) on my cheeks. They’re small and not itchy. I’ve always had redness on them but never these little bumps. I can pop them pretty easily but try to leave them alone. My routine is as follows:

AM 1.Cleans with cosrx low ph good morning gel cleanser 2. Apply The Ordinary 10% niacinimide 1% zinc serum 3. Cerave daily moisturizer + Cerave sunscreen

PM

1. Cleanse with Cerave SA cleanser
2. Cerave daily moisturizer

Products im interested in incorporating to assist with the bumps (and maybe redness)

1. The ordinary BHA + AHA solution
2. Naturium Azelaic 10% topical acid
3. Medicube zero pore pads

How would I incorporate these into my routine? Is there anything I should be aware of with interactions of any of these products? I know the bha exfoliator isn’t for daily use but I’m unsure of the other two products. My skin isn’t sensitive but it is acne prone.

TIA!
