PURPOSE: This study aimed to investigate the effects of hyaluronic acid rejuvenating complex, polycaprolactone, and their combination on skin wound healing, assessing their potential to accelerate tissue regeneration and optimize healing outcomes. MATERIALS AND METHODS: Forty eight Wistar Albino rats were randomly divided into four groups. Group 1 received hyaluronic acid rejuvenating complex injection, Group 2 received polycaprolactone injection, and Group 3 received a combination of both. Group 4 served as the control, undergoing incision without intervention. Skin biopsies were collected at baseline, day 7, and day 14 postincision. Wound healing was evaluated histologically using hematoxylin and eosin (H&E) and Masson's trichrome staining, focusing on epithelial thickness, collagen synthesis, and inflammatory cell infiltration. RESULTS: The combination therapy group (Group 3) exhibited the most pronounced wound healing response, demonstrating significantly accelerated re-epithelialization, enhanced collagen deposition, and well-structured granulation tissue by days 7 and 14. Additionally, inflammatory cell infiltration was markedly reduced, indicating a faster transition from the inflammatory to the proliferative phase. Compared to single-agent treatments, the combined approach resulted in superior tissue remodeling and a more efficient healing process. CONCLUSION: The dual administration of hyaluronic acid rejuvenating complex and polycaprolactone offers a synergistic effect, significantly enhancing skin wound healing compared to monotherapies. These findings highlight the potential of combination therapy as a promising strategy for improving wound repair and tissue regeneration in aesthetic and regenerative dermatology.
