Survey of safety practices of laser and non-laser optical radiation sources used in aesthetic laboratories in Greece

The use of non-ionizing radiation for aesthetic purposes is steadily increasing, with aesthetic laboratories frequently employing lasers, IPL, UV, and LED devices. In Greece, as in many countries, no regulatory framework exists to ensure the safety of clients and operators, despite international recommendations for harmonized oversight.This study aimed to document device use, safety measures, and operator knowledge in Greek aesthetic laboratories. An electronic questionnaire was distributed to the 964 members of the Federation of Professional Associations of Diplomated Aestheticians of Greece (O.S.E.D.A.E), with 120 responses (12.4%). Among the participants 91 of the them were scientific supervisors of a laboratory.Results showed that 85% of (the 91) aesthetic laboratories used lasers (12% more than one type), 50% used LED, and 33% employed IPL systems. Although few injuries were reported, approximately 60% of respondents lacked an accident protocol for lasers, and over 70% lacked one for IPL and LED. Furthermore, from the answers of all participants (120), indicated that safety measures were applied mainly for clients, while warning signage was often absent. Training on device use and safety was provided primarily by suppliers. Respondents identified equipment maintenance and operator training as the most important safety measures, and most of them expressed strong interest in further education.The findings highlight the need to strengthen the safety culture surrounding the aesthetic use of optical radiation in Greece.
