Sudden uniform white pimples - FA, allergic reaction or else?

Hi, yesterday my face has broken out in strange uniform white pimples, and there’s redness in the pimple area. It started with what looked like a red spotty rash on my temples, and it’s spreading to my cheeks. The area is ITCHY. I have been a long time acne struggler, but this type of acne is new. I put The Inkey List 10% Azelaic Acid Serum on it last night, and finished off with the Simple hydrating light moisturiser, but to no avail. It’s really bad now and I’m getting super uncomfortable to go out, I’ve already canceled plans as I feel embarrassed.

I am concerned that it is either a) fungal acne or b)an allergic reaction or something else

Products I use: I usually alternate between using the The inkey list hyaluronic acid cleanser or the Revitale Advanced sulfur soap (from Amazon) for cleansing, as this has seemed to help my previous acne struggles. I wash my face with just water in the morning.

As for moisturiser - I always use the Simple hydrating light moisturiser and sometimes layer this io a few times, as well as using the Glowhub Hydration hero for when my skin feels particularly dry.

IMPORTANT INFO:

I have been staying with my boyfriend’s family, and my bf has to shave very regularly, and whenever his facial hair grows back it irritates me and hurts when we kiss etc. It feels like micro needling lol. I also suspect that his family’s washing powder/hand soap might irritate my face as my general acne worsens when I’m at theirs.

Thank you for reading this and I’d appreciate ANY advice :))
