I'm curious about how long the volume-boosting Juve Look lasts!

I went on a really intense diet, but instead of losing weight, only the fat on my cheeks and nasolabial folds disappeared. ㅠㅠ

I look really haggard and older than my age, so I'm seriously looking into ways to naturally add volume. I'm scared that fillers might sag over time, but the Juvelook procedure, which stimulates the body's own collagen, is super hot in the community, so I thought, "This is it!" However, since it costs quite a bit per session, the most critical factor seems to be how long the effects last. I'd appreciate it if you could give me some fact-checking on how long the plump volume typically lasts after about three consistent sessions, and share your personal experiences regarding the duration of the results. If it lasts long enough to make the money worthwhile, I'm fully ready to open my wallet right away!
