Would the Volneumer procedure be good for when my face looks sunken?

I've lost some weight in my face lately, so I'm looking into Volneumer.

I don't really get a sense of exactly what the difference is between skin Botox and regular lifting.

I wonder if it just provides elasticity,

My face looks a bit sunken, so please make it plumper. I want to see it, but I'm also worried that if I block it out too much, it might cause side effects.

Or like the feeling of really gaining weight

Is the volume filling up?

And I looked it up, so what is the effect of Volneumer for seeing properly?

I'm worried because the pain, bruising, and downtime vary for each procedure.

I would appreciate your advice.
