I went there because I was concerned about my nasolabial folds, and because I had an inexplicable aversion to fillers, I chose Juvelook Volume, which is said to fill in naturally. Regardless of the doctor's skill, I'd like to recommend Juvelook Volume to thin people. Since the nasolabial folds and the surrounding area inevitably gain volume, you may end up with an unwanted face shape. I highly recommend it to people who want chubby cheeks. I think nodules won't be a problem if you go to a hospital that's good at hydration, but collagen hyperplasia is the real problem. If that happens to me, it would be a big problem, and I've seen a lot of people try Yanok injections, Potenza, and acupuncture from then on... (Other reviews) I think it's a procedure that you have to be careful with.
