The reason I froze just now while looking in the mirror... Why are there two horizontal lines on my neck?

I was just staring in the bathroom mirror and was completely stunned. I tilted my head back slightly to check if the lipstick color matched the outfit I was wearing today, but the two distinct lines etched across my neck seemed to be mocking me. I was so dumbfounded that I just stood there blankly for quite a while. I’ve always taken pride in the elasticity of my face, but it seems my neck was from a completely different world. Actually, I suspect it might be because I’ve been too obsessed with calming breakouts around my chin. Since my skin goes crazy at the slightest sensitivity, I’ve always just used soothing pads and focused solely on calming treatments. It’s upsetting, though, that I completely neglected my neck skin and it seems to have manifested as wrinkles. I took a picture of my neck to start keeping a record, and compared to my face, it definitely lacked moisture and the texture was rough. I feel a bit remorseful for having neglected my overall balance while being so focused on calming breakouts. From now on, I plan to check and record the condition of my skin from my neck up to my chest every day, rather than just looking at my face. Although I’m flustered by this sudden discovery of wrinkles, it has made me seriously consider expanding the scope of my skincare routine. Everyone, don't forget your neck when you're taking care of your face. Before you face a ridiculous moment like I did.
