Can someone recommend a cystic acne safe cleanser?

Mid30s F
Since starting B12 injections, I have been having terrible skin. Lately my acne has become cystic (?) with big painful nodules that are hard and take weeks if not months to heal. I need to carry on my treatment because I’m B12 deficient, so all I can do is try to make my situation less painful. I’ve been using CeraVe Hydrating foaming oil cleanser for about a year now because my skin can be very dehydrated, but I’d love to know if someone with a similar type of acne has found a better alternative. Should I switch to Aveeno Calm and restore cleanser?

My current routine is:

SKIN1004 Madagascar Centella Ampoule
Bioderma Sebium Hydra moisturiser
SKIN1004 Madagascar Centella Hyalu-Cica Water Sun serum SPF50+

Has anyone had a similar type of acne, what helped you make it less severe?
Would it make sense to use retinal or would it destroy whatever is left of my skin barrier?
