Abstract

Abstract Background The Hybrid Cooperative Complexes of high and low molecular weight hyaluronic acids (HHCC) improve skin structure and bioactivity. Massive weight loss damages cellular composition and morphological structure of skin. An injective treatment of postobese skin consisting of HHCC may have a role in counteracting these histopathological alterations. Objectives To analyze the histological effects of HHCC injection in the cutaneous tissues of massive weight loss patients suffering from arm laxity. Methods Nine ex-obese patients with postweight-loss-related arm laxity and ptosis requiring brachioplasty were prospectively recruited at the first author's department. HHCC injection was performed on only 1 arm, which included 2 injective sessions separated by 30 days. One month posttreatment, patients underwent a bilateral brachioplasty, and the surgical specimens were histologically examined, searching for any variation in the cutaneous connective tissue following injections. Histology on treated specimens showed a statistically significant increased density of elastic fibers along with a lower fragmentation of the same fibers compared to the untreated tissue. Fibroblasts demonstrated a swollen appearance as if involved in a bioactivation process. Results Treatment with HHCC increases the number of elastin fibers and determines a more regular elastin deposition and architecture, as well as the bioactivation of fibroblasts. The contralateral untreated area showed an irregular structure with elastosis and elastolysis. Conclusions More studies are necessary, but histologically proven benefits are demonstrated in the HHCC-treated skins when compared with basal controlateral skin. These data support the use of HHCC formulations for the treatment of postobese skin laxity. Level of Evidence: 5
