Which of the following is the last step in preparing a client's skin for waxing on the face?

The appropriate final step in preparing a client's skin for facial waxing is to dry the client's skin. This is crucial because any moisture left on the skin can interfere with the waxing process, leading to ineffective hair removal and potential irritation. Wax adheres best to dry skin, allowing it to grip the hair effectively. If the skin is still damp, the wax may not adhere properly, resulting in an incomplete hair removal experience and possibly discomfort for the client.

To ensure a successful waxing session, it’s essential that the skin is thoroughly dried before proceeding. Other methods, such as applying soothing lotion, cleaning the skin with alcohol, or moisturizing, typically occur before the drying step. These actions are important for preparing the skin by ensuring it is clean and free from oils or debris, but they are not the final step before waxing.
