Longevity Aesthetics: A Conceptual Framework for Integrating Pro-Aging Medicine Into Surgical and Non-Surgical Practice

Abstract The prevailing paradigm in aesthetic medicine is the "anti-aging" model, which focuses on correcting and/or reversing visible signs of aging. However, contemporary Geroscience reconceptualizes aging as a malleable biological process driven by defined hallmarks, offering an opportunity to align aesthetic practice with fundamental aging biology. This article explores the concept of "pro-aging" or "longevity aesthetics, " a framework that prioritizes tissue function, resilience, and biological integrity alongside phenotypic improvement. The skin is presented as an accessible model organ that reflects key hallmarks of aging and their clinical manifestations. While conventional aesthetic interventions effectively address structural changes, they often do not target upstream biological drivers of tissue aging. Within this framework, certain surgical and non-surgical modalities may theoretically support tissue resilience through modulation of inflammation, collagen remodeling, and microvascular health. Importantly, some of these strategies, such as biostimulatory injectables including calcium hydroxylapatite (CaHA) and poly-L-lactic acid (PLLA), as well as combination treatment approaches, are already integrated into clinical practice, whereas others remain in the translational or research domain. Emerging concepts such as multi-omics, defined as the integration of genomics, transcriptomics, proteomics, metabolomics, and epigenomics, may further enable personalized and predictive approaches in the future. Longevity aesthetics therefore represents a conceptual evolution from correction to functional preservation. However, direct clinical evidence supporting its biological impact remains limited, and these concepts should currently be interpreted as hypothesis-driven. Advancing this framework will require prospective studies integrating biomarkers with long-term clinical outcomes. Ultimately, this approach positions aesthetic medicine to contribute to translational Geroscience, provided innovation is guided by methodological rigor and ethical transparency.
