I want to know about neck wrinkle treatment

I usually pay a lot of attention to my facial skin, but one day, I suddenly noticed a horizontal wrinkle clearly visible on my neck when I looked in the mirror.
As I get older, I lose elasticity, or maybe it's because of my posture when working or looking at my smartphone, but I think my neck wrinkles are getting deeper, so I'm thinking about getting some help with neck wrinkle treatment.

When I looked up reviews on YouTube and blogs, I found that there are so many different types of neck wrinkle treatments, from lifting equipment to skin boosters like Juvelook and Rejuran.
I've heard that the skin on the neck is thin and sensitive, so consistent care is essential, and that it's difficult to recover once it occurs.

Regarding this...
They say that in order to properly improve elasticity, you need to repeat neck wrinkle treatments to produce collagen and make your skin smoother. How many neck wrinkle treatments do I need to receive to relieve deep wrinkles?
I am curious about what treatment combinations people who are concerned about horizontal wrinkles usually choose.

Is it possible to return to daily life right away after the procedure?
I look forward to your valuable reply!
