Has anyone seen results from a collagen booster?

My skin isn't as elastic as it used to be these days.
I'm looking into dermatology procedures, and collagen boosters caught my eye.

I've heard a lot about lasers and lifting procedures, but
I became interested in collagen boosters because I heard they are a procedure that helps produce collagen deep within the skin.
If you look at reviews, there are people who say their skin texture has improved.
I've also heard a lot of people say that the elasticity seems to have naturally improved.
I am curious about the experiences of those who have actually received it.

In particular, I want to know how effective the collagen booster is.
I heard that changes appear over time rather than immediately after the procedure.
I'm curious if you felt any improvement in skin elasticity or texture.

Also, what do you think are the advantages of collagen boosters?
Rather than artificially noticeable changes
I tend to want my skin condition to improve naturally.
I want to hear about the actual satisfaction level.

There are various types, so I don't know which product I received
How severe was the pain?
I am also curious how long the effect lasted.

If anyone has received a collagen booster treatment, please share the effects and benefits.
Please leave an honest review, including your satisfaction level.
I would like to use this as a reference when deciding on the procedure.
