I have a minor depression in the preauricular area on only one side of my face. 1.5cc of sculptra was injected into that area. The injector told me I need to come back 2 more times and inject 1.5cc each time. Is that amount the norm? Is it too much or too little? Also, I get bumps and scars when I get sutured. I read that sculptra is made of suture material. Does that mean I will get granulomas and nodules?
