Quick way to control acne breakout?

It’s the end of the semester for me (college) and I’ve been super super stressed because of finals, papers, etc. I just finished a major paper that was primarily stressing me out, and my chin is really broken out. I have a huge cystic pimple on my chin. My husband and I are supposed to take Christmas pics on Thursday and I need to get rid of this thing 😞 I never get acne like this and it’s horrible timing.

I have a face mask that I used just on my chin which shrunk it a lot but it’s very drying and you’re only supposed to use it like twice per week. I’ve been using diluted tea tree oil on it and blemish bully gel. It’s helping it go down but it’s still huge and red!! I’m not sure what else I could do to help it.

I use Tatcha Deep Cleanse face wash also. And then my normal toning and moisturizing routine.

Does anyone have any tricks to help clear this up within the next few days??
