The so-called nanofat is a novel technique derived from lipofilling that corrects and lightens pigmented dark circles under the eyes. It's a form of fat grafting to regenerate and revitalise the skin. It consists of the injection of stem cells, which are obtained from the fat extracted by means of a small liposuction, which is then treated to emulsify it, eliminate the cells and concentrate the part of the stroma, rich in stem cells and with a great stimulating and regenerating capacity. This emulsion isn't used to give volume, but to repair tissues atrophied by ageing, to improve fine wrinkles, to correct imperfections and irregularities and to treat the dark pigmentation that can be seen in some people. These cells are used to smooth and correct wrinkles after the pigmentation of the skin, eliminating dark circles under the eyes.

La finalidad de nanofat es poder inyectar de manera aislada, solamente esas células madre con el objetivo de regenerar y recuperar aquellos tejidos que se han ido envejeciendo y degenerando con el paso de los años. Es un tratamiento que no surge con la idea de aportar volumen como otros injertos grasos, sino que surge para revitalizar los tejidos. De hecho, con la técnica del nanofat no se inyectan adipocitos (células grasas) sino que cuidadosamente se eliminan de la emulsión a inyectar.
