Fat grafts enriched with ex-vivo expanded adipose stem cells improve hyperpigmentation of face.

Facial contour deformities associated with pigmentary changes are of major concern for plastic surgeons being difficult to treat. No definite ideal treatment option is available to address simultaneously both the contour defects as well as related hyperpigmentation. The aim of the current study is to compare long-term effects of conventional adipose tissue grafting and ex-vivo expanded ASC-enriched adipose tissue grafting for the treatment of contour deformities related pigmentary changes on the face.
