Could it be the change of seasons? I'm getting more small pimples.

As soon as the change of seasons started, tiny pimples suddenly broke out all over my face.
My skin wasn't particularly sensitive, but as the weather started getting chilly and dry,
My forehead, cheeks, and even under my chin were covered in bumpy millet, almost unbelievably.
The feeling on my fingertips is too gritty when washing my face.
I keep unconsciously touching it with my hands, but when I try to squeeze it out, it only leaves a red scar and shows no signs of calming down.
Even when I try soothing pads or hydrating ampoules, the relief is only temporary, and new small bumps appear again when I wake up in the morning. Given my current situation, is it right to just blindly slather on moisturizing products, or would it be faster to get a scalp scaling or acne treatment? I would be really grateful if you could share any tips or skincare routines for those with similar experiences.
