What is the biggest advantage of Belotero among imported fillers?

Lately, every time I look in the mirror, I notice that the area under my eyes and the front of my cheeks are deeply sunken, making me look completely tired and older ㅠㅠ I lost some weight while dieting, but strangely enough, only the fat on my face vanished, so I look like a skeleton lol. I heard that imported products last longer and look much more natural, so I'm looking into them, and among them... Belotero So many people recommend it! Even if you get it fitted around the nasolabial folds or the corners of the mouth where there is a lot of facial movement. Belotero I'm wondering if it's really true that it adheres perfectly without any foreign body sensation. My skin is on the thinner side, so I'm curious how long the bruising or swelling lasts, and if it naturally adds volume. Belotero I would be very grateful if those of you who have tried this could leave some real-life tips on what advantages this treatment has over other products.
