What should not be done prior to performing a facial on a client?

Using harsh exfoliants or peels prior to performing a facial on a client is not appropriate because it can lead to skin irritation, over-exfoliation, or an adverse reaction. This step can compromise the skin's barrier, making it more sensitive or inflamed, which is counterproductive to the goals of a facial, which are to cleanse, hydrate, and rejuvenate the skin.

In preparing for a facial, engaging in light conversation can help establish rapport with the client and make them feel more comfortable. Similarly, applying toner is typically part of the facial preparation, as it helps to balance the skin’s pH and remove any residual impurities. Checking the client's skin type is also crucial for tailoring the facial products and techniques appropriately, ensuring the treatment is effective and safe for their specific skin needs.
