C2

[Music] c2 lies at the apex of the chin and it's interesting to see that most of the people would start by injecting c2 rather than c1 because they want to achieve an increase in vertical dimension however it's not uncommon if you only treat c2 to make the chain longer that you will worsen the depression that we have at the level of the label mental angle which is c1 so usually when i have to address the vertical height of the chin i start injecting c1 and then i go to c2 but you know c2 has different layers to inject do you know which they are just let me know
