Adipose tissue is consider to be a natural, homogenic, autologous, non-allergenic, easily available, low cost, versatile use, permanent correction filler.
Different lipofilling techniques have been described in literature; Coleman’s technique, based on the minimally invasive obtainment, preparation through centrifugation, and multilevel infiltration of the fat, Amar’s technique, based in the infiltration of the fat directly into the muscles for better blood supply, and Yoshimura’s technique or microlipofilling based in the micro harvesting and micro delivery of the fat parcels.
Lipofilling material might produce a long-lasting effect, estimated in years, although certain studies show variable reabsorption, between 30-60%, in ten months.
Disadvantages of the technique include: harvesting and anesthesia phases required, lack of availability in lipodistrophies, and unpredictable reabsorption.
The adverse effects of the technique described are injection site edema, calcification, donor site morbidity (pain, infection, scars, etc.), unpredictable reabsorption, irregularities, fibrosis and adipose embolism.
Great interest has raised recently in the medical community regarding the use of fat injections related to the regenerative capacities of the mesenchymal cells present within it, with multipotential capacities that allow not only a volumetric effect but cutaneous improvements.
