It's such a depressing day because tiny pimples suddenly broke out on my forehead.

I have dry skin and don't usually get acne, but when I woke up this morning and went to wash my face, I found my entire forehead covered in small, bumpy pimples.
It felt rough to the touch, like grains of sand rolling around, and under the light, the red bumps were all visible, so my stress exploded this morning.
I don't know the cause—whether the new base makeup I recently switched to clogged my pores, or if my skin broke out because I went out for a long time these past few days when the fine dust levels were high.
I was worried that squeezing it carelessly with my hands would leave a large scar and cause it to spread, so in the morning I just lightly washed my face with water, applied a very thin layer of moisturizer, and went to work.
I was self-conscious about covering my forehead with my bangs even at work, and trying to cover it up with makeup only made the unevenness look more prominent, so I spent the whole day sighing while staring in the mirror.
As soon as I get off work today, I think I need to use an enzyme cleanser to gently dissolve the old dead skin cells and impurities deep within my pores and soothe my irritated skin.
Then, I plan to apply a chilled Centella Asiatica extract mask from the refrigerator to cool down the heat, apply a thick layer of acne spot treatment ointment to my forehead, and go to sleep.
I earnestly pray that this first aid will be effective and that by tomorrow morning, these tiny bumps on my forehead, which feel like unwelcome guests, will have subsided at least a little.
If you happen to have any super effective soothing products that worked instantly for sudden breakouts like mine, please recommend them along with some words of comfort in the comments.
