MICROBIOLOGICAL ASSESSMENT OF SHARED MAKEUP PRODUCTS REVEALS THE INCIDENCE OF STAPHYLOCOCCUS SP. CONTAMINATION

Abstract

ABSTRACT

Introduction: Makeup has become an indispensable ally in the daily routine of many women. However, the practice of sharing cosmetic products among different users can represent a significant vector for the transmission of microorganisms, particularly bacteria and fungi. Items such as lipsticks, mascaras, brushes, and sponges, when used by more than one person, facilitate cross-contamination, which can lead to skin infections, conjunctivitis, and other dermatological conditions. Accordingly, the objective of this study was to analyze the microbiological profile and to determine the occurrence of S. aureus and S. epidermidis in shared cosmetic items. Methods: This is an experimental study with a quantitative and descriptive approach, in which the samples were provided by the campus students and subjected to microbiological analyses to assess contamination. Results: The study revealed that shared-use cosmetics can exhibit significant microbial contamination, particularly by Staphylococcus aureus and Staphylococcus epidermidis. Microbiological analysis of these products is essential to identify risks and guide preventive measures. Conclusion: In conclusion, preventive measures such as regular cleaning of applicators, proper storage of cosmetics, and avoiding the use of shared or expired products are essential to reduce contamination risks. Strict adherence to good practice protocols by manufacturers and beauty professionals is also crucial to ensure product quality and user safety.
