Hyaluronan Hybrid Cooperative Complexes Injection as a Biostimulation for Postobese Skin Laxity in the Arm: A...

Area of Science:

• Dermatology
• Plastic Surgery
• Regenerative Medicine

Background:

• Massive weight loss significantly alters skin structure and cellular composition, leading to laxity and ptosis.
• Post-obese skin exhibits histopathological changes that may benefit from targeted interventions.
• Hyaluronic acid-based treatments, like Hybrid Cooperative Complexes (HHCC), show promise in improving skin quality.

Purpose of the Study:

• To histologically evaluate the effects of HHCC injections on the cutaneous tissues of patients with arm laxity due to massive weight loss.
• To assess the impact of HHCC on elastic fiber density, fragmentation, and fibroblast morphology in post-obese skin.

Main Methods:

• Prospective study involving nine ex-obese patients undergoing brachioplasty for arm laxity.
• HHCC injections administered in two sessions, 30 days apart, to one arm.
• Histological examination of treated and untreated (contralateral) arm skin specimens one month post-treatment.

Main Results:

• Statistically significant increase in elastic fiber density in HHCC-treated skin compared to untreated skin.
• Reduced fragmentation and improved architecture of elastic fibers observed post-HHCC treatment.
• Fibroblasts in treated areas showed a swollen appearance, suggesting bioactivation.

Conclusions:

• HHCC injections demonstrably improve skin histology by increasing elastin and promoting fibroblast bioactivation.
• The findings support the potential of HHCC formulations for treating skin laxity in post-obese individuals.
• Further research is warranted, but histological evidence suggests HHCC is beneficial for post-obese skin.
