INFECTION, TRACEABILITY, AND BIOLOGICAL EVIDENCE: INTERFACES BETWEEN AESTHETIC BIOSAFETY AND FORENSIC ANALYSIS

Abstract

This study analyzed scientific evidence published between 2021 and 2025 regarding infection risks in aesthetic procedures and methodological advances applied to forensic investigation of biological traces, with the aim of identifying convergences between both fields in terms of microbiological control, material traceability, and dependence on validated technical protocols. The synthesis of results showed that, in the aesthetic sector, contamination is not an isolated event but a systemic phenomenon associated with the lack of continuous inspection, the use of previously contaminated products, and the fragmented execution of biosafety standards. Findings demonstrate that the risk is not limited to the moment of the procedure but involves the entire production chain, from cosmetic manufacturing to post-procedure disposal.In the forensic field, the studies point to a rupture with the traditional model of analysis based solely on the visible presence of biological fluids. New approaches, such as microRNA profiling, cellular autofluorescence, and Y-STR typing, allow the identification of degraded or non-detectable traces, expanding evidentiary capacity in sexual assault cases with no semen or scarce biological material. The comparison between the two fields shows that both face similar structural failures: the production of risk or error does not stem from the absence of technology, but from its slow incorporation into professional and regulatory routines.It is concluded that the effectiveness of biosafety practices and scientific investigation depends on the articulation between technical evidence, updated regulation, and continuous professional training. Without this alignment, systems continue to transfer institutional failures to individuals exposed to clinical or judicial harm.
