Is Juvelook the right choice for filling in hollows and adding volume under the eyes?

I am in my 30s and have been very worried lately because, as I get older, I have lost weight in my face overall, and the area under my eyes and the sides of my cheeks look particularly sunken. Every time I look in the mirror, my complexion looks tired and I look much older, so I considered getting fillers, but I was afraid it might look unnatural. That is why I learned about the Juvelook procedure, which is said to naturally stimulate the body's own collagen to restore volume, so I am leaving this question.

I looked it up online and heard it's really good for filling in scars or sunken areas without looking artificial. I'm wondering if Juvelook is a good fit for people like me who have thin, youthful faces. For those who have received this treatment, do you really feel a noticeable plumping effect? ​​I'm a little worried because I heard that side effects like nodules can occur.

I would also like to know how painful the procedure is since it involves injections, and how many sessions are typically required to maintain the effect of firming the skin from deep within. I am worried that severe bruising or marks might remain after the procedure and interfere with my work life, so if there are any experienced users, I would really appreciate your honest answers or advice regarding the Juvelook treatment. Since this is a costly procedure, I want to make a careful decision, so I look forward to your comments!
