What can a person using a beauty preparation do to a client's body?

The correct choice is that a person using a beauty preparation can temporarily remove unwanted hair. This falls within the scope of cosmetic services that licensed professionals can offer, such as waxing, threading, or using depilatory creams. These methods are considered non-invasive and are commonly performed in salons and beauty establishments, making them appropriate for licensed cosmetologists.

In contrast, the other options either describe services that are outside the realm of typical beauty preparations or involve procedures that require additional medical qualifications or licenses. For example, applying cosmetics solely for visual appeal does not encompass the range of services that a licensed professional can perform, as beauty preparations often include more than just cosmetic application. Invasive surgical procedures require medical expertise and are not permitted for cosmetologists. Administering chemical peels may also require further specialization and is generally governed by specific rules beyond standard beauty preparation practices. Thus, the answer emphasizes the capability to perform temporary hair removal, which is a common and accepted practice within the cosmetology field.
