What is a key requirement for paraffin wax used in services?

The key requirement for paraffin wax used in services is that it must be discarded after a single use. This is primarily due to hygiene and sanitation concerns. When paraffin wax is used in services such as hand or foot treatments, it can become contaminated with bacteria, dead skin cells, oil, and other impurities. By discarding it after one use, practitioners ensure that clients are not exposed to these contaminants, which could potentially lead to infections or other adverse health effects.

Using paraffin wax multiple times or storing it in open containers would compromise its sanitary quality and pose a risk to clients. Additionally, while paraffin wax does not require extensive sanitation like other tools or surfaces, maintaining its cleanliness prior to each use is vital. Following this requirement helps protect the health and safety of clients while upholding professional standards in the service.
