I have a pimple on my forehead... I need home care urgentlyㅠㅠ

This morning, I was washing my face when I looked in the mirror and almost screamed... A huge, red pimple had formed right in the middle of my forehead. It's winter, so it's cold outside and the heaters are so dry indoors that my skin's been going crazy, but having a breakout like this is incredibly frustrating and upsetting. I'm usually quite timid, so when something like this happens, I worry about it all day. Honestly, I had some leftover chicken in the fridge from yesterday, so I held back from eating it as a late-night snack. But my skin still feels like this, and I feel a bit resentful. So today, I decided to take out all the moisturizing and soothing face masks I could find and focus on my home care routine. It really reaffirms how important it is for sensitive skin to maintain a good home care routine. If I diligently follow these home care routines, I'm sure this pimple will be smaller by tomorrow morning, right? I really hope so... If you know of any good soothing cosmetics, please let me know.
