[Routine Help] is it better to use low % bha frequently or high % bha 1-2x weekly

Beauty Tips For Body Care
I've been trying my best to get rid of blackheads and tighten my pores. But nothing seems to work . I've used various products from cosrx bha liquid, Paula's choice BHA 2% and The ordinary peeling solution. As of now there has been little to no changes . My face is still very oily and my nose is filled by these tiny black dots filling up my pores ( probably SF, but i still have blackheads on my cheeks).So I've been wondering whether is it better to use a lower % bha so i can apply it daily / once every 2 days instead of once/twice a week with a high % bha so that it can clean my pores more frequently throughout the week?
