Prevention of Belotero spreading on the nose and lips and same-day procedure availability

Hello, I am writing to inquire because I would like to naturally raise the tip of my nose slightly, and improve the lip volume and corners of my mouth line that are currently trending. I am currently researching Belotero products in detail because I want to make my overall flat facial features look more distinct and three-dimensional.

I have read various reviews online, and I am very worried because I learned that since the nose and lips are sensitive areas, if the injection is applied incorrectly, it can spread sideways over time and actually make the face look blunt. I am wondering if using Belotero products would be more advantageous in preventing this clumping or spreading phenomenon due to their unique cohesive properties.

Also, to prevent side effects, I would like to make sure that only genuine, accurately measured Belotero with proven safety is being used.
