I am concerned about the difference in skin tone between my face and neck, as well as neck wrinkles. Please give me some advice.

Hello. I am writing to ask a question because there is something about my skin that is really bothering me. It is difficult for me because the difference between my facial and neck skin tones is so severe. My face is on the brighter side because I use face masks and take meticulous care of it, but perhaps because I haven't paid as much attention to my neck, it looks dull and dark, making it feel like my face is floating unnaturally.
On top of that, I'm worried because my neck wrinkles seem to be getting noticeably deeper. Is there an effective way to brighten my neck skin tone to match my face while also caring for my neck wrinkles? I'm at a loss as to whether I should use a neck-specific cream or cosmetics containing specific ingredients, or if I need to get a procedure. Please share any skincare routines that have worked for you or any care methods you would recommend.
