What could be the reason for the sudden skin troubles I've been getting lately?

Lately, I've suddenly been having a lot of skin troubles, and it's really stressing me out. I didn't usually have any issues, but at some point, tiny bumps started popping up or I suddenly got pimples.

I haven't really changed my cosmetics recently, and my lifestyle doesn't seem to have changed much, so I don't know why this is happening. Could my skin have become sensitive because of the change of seasons? Or is it due to stress or my physical condition...

I've been paying more attention to my cleansing routine and switching to the gentlest skincare products possible, but I haven't noticed a significant difference yet. I'm also being cautious because I'm worried that touching it further might make it worse.

Is anyone else experiencing sudden breakouts like me?

I'm curious how you manage this kind of situation. If anyone knows the cause or solution, please share.
