How about Juve Look volume for sunken cheeks and nasolabial folds?

I tried dieting a little lately, but instead of losing the belly fat I was hoping for, my face—especially the sides of my cheeks—has sunken in, turning my face into a total peanut shape. ㅠㅠ It’s so upsetting that I look like a skeleton, making my impression look sharp and making me look much older than I actually am. I'm afraid regular fillers might sag or shift over time, so I'm seriously considering Juvélook Volume, which allows new tissue to naturally fill in from deep within my skin. I think the biggest advantage and appeal is that it creates volume gradually and naturally without feeling like a foreign substance. For those of you who have personally received Juvélook Volume on your sides or sunken nasolabial folds, I'm curious to know if you experienced the amazing satisfaction of seeing it fill in like your own flesh after a few months!

I heard that it looks puffy right after the first injection due to swelling, but gradually subsides. How many days should I expect the swelling to go down? I also heard this procedure is best recommended for people with thin skin and little facial fat. Please share your real experiences regarding how long the Juvelook volume usually lasts once it settles.
