Where should you test the temperature of a towel for facial steaming?

Testing the temperature of a towel for facial steaming on the wrist is the most appropriate method because the wrist is a sensitive area that reflects the surface temperature without exposing a more vulnerable part of the body to potential burns. The skin on the wrist is thinner and more sensitive than areas like the back of the hand or the cheek, making it a reliable indicator of how hot the towel will feel on the face.

Using the wrist as a testing point allows for an assessment of the towel's warmth while minimizing the risk of discomfort. The forehead and cheek, while sensitive, may not provide as accurate a gauge of the temperature before applying the towel to the client's face, and the back of the hand could also lead to discomfort if the towel is excessively hot. Therefore, testing on the wrist ensures the towel will be warm and soothing, enhancing the client's facial steaming experience safely.
