Question) What could be the reason for sudden skin breakouts?

I'm really worried because I've suddenly been getting constant breakouts lately. I used to not get them often, but lately they keep popping up on my chin and cheeks.

I haven't specifically changed my cosmetics, and it doesn't seem like my lifestyle has changed much, so why is this happening?

I'm wondering if it's due to the change of seasons, or if it's the influence of stress or hormones.

It would be helpful if those of you who have had similar experiences could let me know how you managed it. 🙏
