I have deep horizontal wrinkles on my neck. Can this be improved?

Lately, I'm more concerned about neck wrinkles than facial ones. I do spend a lot of time looking down at my phone, but at some point, I noticed several horizontal lines forming on my neck. At first, I thought they were temporary wrinkles caused by my posture, but the lines remain even when I hold my head up. Perhaps because the skin on the neck is thin, I don't feel much of a difference even though I apply moisturizer consistently.

Does the treatment method for neck wrinkles vary depending on their cause or depth? They aren't deeply etched yet, but I'm concerned because they appear in multiple layers, including fine lines. I've seen that neck wrinkle Botox, skin boosters, and lifting procedures can be helpful, and I'm curious about the differences between them.

I have heard that the neck is a more delicate area to treat than the face, so I would like to know about potential side effects and the recovery period. I would appreciate responses from hospital staff regarding whether existing horizontal wrinkles can be improved, and which procedure would be best to consider for naturally managing both neck skin texture and elasticity.
