I'm curious about what kind of home care you use when you get a pimple on your forehead.

A red, hard pimple has formed in the middle of my forehead. What should I do? My skin is already incredibly dry and itchy in winter, and being constantly exposed to the heater indoors seems to be making it worse. I'm so depressed and worried all day. I've been paying close attention to my home care routine, using face masks, and such, but when my skin suddenly turns upside down like this, I wonder if I'm doing something wrong, and I'm getting increasingly anxious...

Does anyone have any special home care methods when they suddenly break out like this? I have sensitive skin like mine, so I'm afraid that just applying anything will make it worse, so I can't even touch it. But I'm also worried that if I leave it like this, it might not go away until the Lunar New Year holidays. If you have any home care routines or soothing tips that have actually worked for you, please let me know!

It's cold outside, and it's past 7 p.m., so the house seems to be getting drier, so I turned on the humidifier, but I'm not sure if it's enough. If you have any home care tips or product recommendations, please let me know!
