The top layer is called the subcutaneous layer and this is where cellulite occurs. The bottom two layers are the fat reserves where excess calories are stored. Cellulite does not occur in these deeper layers. Directly beneath the subcutaneous fat layer there is a layer of connective tissue comprised of collagen called the .fibrous septae..

Carboxytherapy procedures are very similar to mesotherapy ones. Consequently, injection tecniques are very close with minor adaptations for the. gas to be. injected. in a safe manner.

Neddles to inject CO2 gas are extremely thin. The injection is almost painless because the diameter is as. small à 0.3 mm. In carboxytherapy, the length of each needle is close to 13 mm which is a good. length for the doctor to either target superficial layers of the skin (dermis) either sub-cutaneous deeper layers.. . The physician may also bend the needle's axis when treating plane surfaces such as the decolleté.. . .
