I'm considering Juvelook. How effective is it?

I'm really worried because my face looks lifeless, and my cheeks, in particular, seem sunken. I feel like my skin used to be so firm. Juve Look seems to be really popular these days; I've heard so many people recommend it because it naturally adds volume and helps improve skin texture. I feel uncomfortable with something too obvious, but I think Juve Look would be perfect for someone who wants to look subtly beautiful. What do you think?

I was really intrigued after reading reviews that said getting it on areas where I'm concerned about enlarged pores makes them tighter and the skin firmer overall. However, on the other hand, I'm also worried whether there will be truly noticeable results or if it will just be for my own satisfaction. That's always the case with dermatological procedures... I'd also like to know in advance how long the raised marks after the Juvelook treatment last, and how much pain is involved.
