I'm worried about the duration of the Belotero treatment and the nodule formation.

Hello. I am looking into fillers because my facial elasticity has decreased and my nasolabial folds have deepened. After searching through various products, I found many reviews stating that Belotero, an imported product, has excellent adhesion and causes minimal foreign body sensation. Since my skin is on the thinner side, I am very worried that the area might become bumpy or show through after the procedure. However, I heard that Belotero allows for customized treatment for different areas because it comes in various particle sizes.
In this regard, I am curious about how long the effects of Belotero typically last. Since it is a bit more expensive than domestic fillers, I am concerned about whether it is worth the price. Also, even if Belotero is injected into areas with a lot of movement, such as around the eyes or mouth, can the results last naturally without clumping or nodules? I would appreciate honest answers from those with experience or experts.
