My neck wrinkles have gotten really deep from constantly using my phone. What is the most effective treatment?

I think I’ve been looking at my smartphone too much lately while lying down with a forward head posture, because when I looked in the mirror, the deep horizontal wrinkles on my neck had become incredibly prominent. I'm only in my early 30s, but these neck wrinkles make me look so much older, and it's really stressing me out. No matter how much neck cream I apply, the deep wrinkles just won't go away. Are skin boosters good for erasing neck wrinkles, or do I need to fill them in with something like fillers? Since it's the neck, I think it will bruise easily and hurt, so please share all the information if there are any really effective procedures.
