Which of the following products is not typically used during vacuum suction treatments?

During vacuum suction treatments, talcum powder is not typically used. Vacuum suction treatments primarily involve the use of products that enhance the treatment's effectiveness and ensure safe application. Moisturizing creams and surgical gels can provide a protective barrier and induce slip during the suction process, enhancing the efficacy of the treatment. Essential oils can also be used for their therapeutic properties and can aid in relaxation and skin benefits during the procedure.

Talcum powder, however, can create a layer that may interfere with the suction mechanism. This powdery substance can lead to an uneven surface, making it difficult for the vacuum to properly adhere to the skin, thereby reducing the effectiveness of the treatment. Thus, it is not a suitable product for use during vacuum suction treatments.
