I’m a patient

Micro reinjection of autologous fat tissue is a major technological advancement which was made possible thanks to the use of a single-use new material whose characteristics have been validated by several years of experimentation.
It consists in making an autograft of fat cells through reinjection of fat taken directly from the patient. It is now possible to take and reinject micro-particles of fat of about 0.5 mm and containing hundreds of cells, and to get closer to the skin deep face avoiding all risks of irregularity. This new procedure has been made possible thanks to the advancement of the material used: the sampling cannulas are smaller, they are 2 mm wide, and the reinjection cannulas are 0.8 mm wide.


Indications in reconstructive surgery

  • Filling of post-traumatic tissue depressions,
  • Improvement of the skin trophicity of scarred injuries of any type and more particularly: burns, radiodermitis, scleroderma injuries, etc.

Indications in aesthetic surgery

  • Plumping effect in particular for the cheekbones, the naso-labial folds, the lips, the temporal region, etc.
  • Filling and smoothing of face wrinkles,
  • This technique can be used alone or in conjunction with another aesthetic surgery procedure, including the cervico-facial face lift.

The 1st consultation

  • After a careful clinical and photographic analysis of the areas to be treated, we’ll define a precise plan of the areas and the quantity of fat tissue needed. Most of the time, the procedure is done under local anaesthesia and can be done in outpatient care or in external care.

The intervention

  • The sampling areas identified during the pre-operative work-up, umbilical sub region, hips, internal face of knees, back, etc.
  • The entry points of the infiltration and sampling cannula need to be anaesthetised with Xylocaine with adrenaline with a very small needle. An infiltration is performed in the whole sampling area with highly diluted Xylocaine with adrenaline in a 2-mm cannula.

Fat tissue sampling

  • The fat tissue sampling can start, manually with a 10-cc syringe and very gentle aspiration; once the sampling is done in about 4 to 6 syringes, the fat tissue must be isolated.


  • Centrifugation allows the separation of the anaesthesia liquid from the fat micro-blocks.


  • Reinjection can start, the entry points have already been anaesthetised, and pre-entry points have been done with a 0.8-mm needle, which will allow the introduction of 0.8-mm micro- cannulas, and the injection of fat tissue in every direction and layer.

Post-operation controls

  • The operation follow-up is very simple. There are no painful phenomena, the swelling is very limited and there are normally no bruises.
  • The result is perfectly stable two months after the operation. Skin trophicity is going to improve over time and post-operation controls will be performed at the 2nd and 6th month.

These fat micro-blocks are going to act as grafts and keep their stability over time.

Furthermore, since the fat cell is a secretory cell, an improvement of the skin quality is going to appear very quickly.

Fat tissue micro-reinjection represents a full surgical intervention. No contraindication or risk related to the use of a local anaesthetic should be identified. The risk of infection related to the surgery remains extremely rare. Overcompensation and reinjection of too much fat tissue must be avoided.

To sum up, micro-reinjection of autologous fat tissue is a new technique which has been made possible thanks to the use of high performance and single-use cannulas.
