Record of skin changes during the change of seasons

Lately, I've felt like my neck is getting drier than my face, so I've started taking care of both.

I'm so worried about the increasing wrinkles on my neck.
I used to only pay attention to my face, but now that I'm taking care of my neck as well, I feel less tightness overall.
It felt more connected than I expected, so it was fascinating. Haha.
Lately, I've been applying the leftover product from my face to my neck as well. Plus, even my elbows, haha.
This is also a small change, but I am satisfied.
Do any of you have a specific routine for neck care? I've seen neck fillers these days, and I'm curious about that too.
