It is in the deep part of the skin but not under the skin. It should not be in the superficial part of skin or can leave a blue colored line.The medical terminology for this area is 'Deep Dermis'Regards
It really depends where you are injecting it, what your goals are, and what product you are using such as Juvederm Ultra or Ultra Plus.In the tear trough area, many physicians prefer a deep injection to avoid visiblity. In other areas such as cheek enhancement injections are also at a deeper level.However, around the mouth, injection on a more superficial layer immediately beneath the skin is desireable.
