Final answer:
The subject of this question is Health, and it relates to the guidelines for dispensing and using cosmetics in a sanitary manner. Applying cosmetics in a lab is generally not allowed, and waste should be disposed of properly.
Step-by-step explanation:
The subject of this question is Health. The question is referring to the guidelines for the dispensing and use of cosmetics. According to the FDA regulations, all cosmetics should be kept in clean, closed containers and dispensed in a sanitary manner. Once a product has been dispensed, it should not be returned to the container. This is to ensure the hygiene and safety of the patrons' skin.
If you are in a lab setting, applying cosmetics is typically not allowed as labs are meant for scientific experimentation and not personal care. If there is an accident while using cosmetics, such as an allergic reaction or skin irritation, it is important to stop using the product immediately and seek medical attention if necessary. Waste from cosmetics should be properly disposed of according to local regulations to minimize environmental impact.
