What is the purpose of using finger cots in manual extraction?

The purpose of using finger cots in manual extraction primarily revolves around preventing the spread of disease. Finger cots serve as a barrier that protects both the esthetician and the client, minimizing the risk of transmitting bacteria, viruses, or other pathogens during the extraction process. Maintaining hygiene in any esthetic procedure is crucial, and using finger cots ensures that the tools used are sanitized and that the esthetician's fingers do not come into direct contact with the skin, further safeguarding against potential infections.

The other options, while they may have their merits in different contexts, do not align with the primary function of finger cots during extractions. Enhancing grip and improving precision may be indirect benefits but are not the main reasons for their use. Additionally, finger cots do not have a role in improving circulation. Their primary focus remains on infection control and promoting a safe practice for both the professional and the client.
