Ultraviolet-C Light-emitting Device Against Microorganisms in Beauty Salons

Area of Science:

• Microbiology
• Public Health
• Biotechnology

Background:

• UV-C light, or germicidal radiation, is a physical disinfection method targeting microbial genetic material.
• It is widely applied for decontaminating environments, water, and food.
• Beauty centers pose infection risks due to potential microbial contamination of tools and surfaces.

Purpose of the Study:

• To assess the antimicrobial efficacy of a novel UV-C device, named Asepsis.
• To evaluate its effectiveness against clinically relevant microorganisms found in beauty salon settings.
• To determine the impact of varying UV-C exposure times on microbial inactivation.

Main Methods:

• Tools commonly found in beauty salons (hairbrushes, nail pliers, makeup brushes, face masks) were artificially contaminated.
• Contaminants included bacteria (Pseudomonas aeruginosa, Staphylococcus aureus), fungi (Microsporum canis, Trichophyton rubrum, Candida albicans, Malassezia furfur), and Chikungunya virus.
• Exposure times to the UV-C device ranged from 1 to 5 minutes.

Main Results:

• A significant reduction in microbial load was observed across all tested items compared to controls.
• Face mask samples demonstrated the most substantial microbial reduction.
• Makeup brushes showed the least microbial inactivation, even after extended exposure periods.

Conclusions:

• The tested UV-C device demonstrates efficient inactivation of common beauty salon contaminants in short exposure times.
• This technology presents a viable physical disinfection solution for beauty centers to mitigate infection risks.
• The device showed promising efficacy against enveloped viruses, suggesting broader applicability.
