Regenerative Strategies in Aesthetic and Reconstructive Surgery: Biological Foundations, Clinical Evidence, and Emerging Technologies

Regenerative medicine has rapidly evolved into a central pillar of aesthetic and reconstructive surgery, integrating cellular therapies, autologous biologics, biomaterials and advanced biofabrication platforms. This review synthesizes evidence from twenty peer-reviewed studies to examine how these modalities contribute to tissue restoration, improve structural and functional outcomes and reshape surgical practice. Cell-based approaches—particularly mesenchymal and adipose-derived stem cells—emerged as the most frequently investigated strategies, reflecting their capacity to modulate inflammation, enhance angiogenesis and promote extracellular matrix remodeling. Autologous biologics such as platelet-rich plasma and regenerative fat grafting also demonstrated widespread application due to their accessibility and compatibility with established clinical workflows. Concurrently, biomaterial-based techniques and 3D bioprinting technologies are expanding reconstructive possibilities, enabling more personalized and anatomically precise interventions. Across indications ranging from facial rejuvenation and breast reconstruction to cartilage engineering and wound repair, regenerative modalities consistently demonstrated potential to improve tissue quality and aesthetic outcomes. Although heterogeneity in protocols and limited long-term data remain challenges, the convergence of biological science, materials engineering and surgical innovation positions regenerative medicine as a transformative paradigm for future clinical practice.
