This project investigates which type of lip gloss applicator accumulates the most bacteria by testing and comparing different applicator designs. The study aims to identify how bacteria build up on cosmetic tools and whether certain applicators are more prone to contamination. This project is important because understanding bacterial accumulation on lip gloss applicators can help improve personal hygiene, reduce the risk of infections, and guide manufacturers and consumers in choosing safer cosmetic products.
This project investigates an interesting health and hygiene question by examining which lip gloss applicators accumulate the most bacteria. The student clearly identifies the research problem and demonstrates an understanding that repeated cosmetic use can allow microorganisms to grow on applicators. The project also shows effort in designing a procedure, culturing bacteria using petri dishes, and comparing results across different types of lip gloss applicators. The visual presentation and organization of the slides help communicate the main idea effectively.
Overall, this project addresses a practical real-world issue and demonstrates thoughtful effort in investigating how cosmetic products may accumulate bacteria.
