[Routine help] How many actives are too many?

For reference, I have extremely oily, acne prone skin (and I mean cysts, blackheads, whiteheads, the lot) and bad hyperpigmentation.

Actives I currently use:

a cleanser with salicylic acid (twice a day)

a salicylic acid lotion (1-2 times a day)

a sunscreen with salicylic acid (1 time a day)

Epiduo (0.1% adapalene, 2.5% benzoyl peroxide) (1 time a day)

But even with all this, I still have a moderate amount of acne.

So, my question… Do you think it would be detrimental to my skin to introduce more actives and also, can you recommend any that would be most compatible/ won’t interfere with the effect of my other actives.

I was thinking maybe azeleic acid?
