What could be the cause of a sudden skin breakout?

My skin has suddenly become sensitive lately
I've been getting breakouts, and my overall condition has gotten worse.

I haven't really changed my cosmetics, either.
It seems like my lifestyle patterns haven't changed much either.
I don't know why this is happening...

Maybe it's because of the changing seasons,
Or I'm confused if it's because of fine dust or stress.

I unnecessarily changed this and that
I can't even touch it for fear it will get worse...

In times like this
I wonder if minimizing the basics is the right thing to do,
Or I am wondering if it would be better to provide more soothing care.

Those who have had similar experiences
I would appreciate it if you could let me know the cause or how you managed it.
