What procedures are available to get rid of neck wrinkles?

Hello. I am someone who is stressed about the deep wrinkles on my neck. Even when I was young, I felt that my neck wrinkles were worse than others', so I was very stressed about it, and as I get older, they seem to be getting progressively worse. I suspect it might be because I spend a lot of time looking down at my phone, and since it has been like this since childhood, I wonder if I was born with severe neck wrinkles. I have heard that there are procedures to get rid of neck wrinkles; what types are available? Please let me know the cost, the frequency of treatments, and the total number of sessions required to see results. Is there a specific age limit for neck wrinkle treatments?
