What is included in the practice of esthetics?

The practice of esthetics encompasses a broad range of cosmetic care services for the face and body. This includes not only facials and body wraps but also treatments that utilize various products to enhance the skin's appearance, such as exfoliation, hydration, and anti-aging techniques. The goal of esthetics is to improve the overall appearance and health of the skin, which involves much more than just a limited set of services.

The other options do not capture the full scope of esthetics. While facials and body wraps are definitely part of the practice, stating that they are the only services included is overly restrictive. Similarly, advanced hair treatments and hair removal with wax do not align with the comprehensive definition of esthetics, which is focused on skin treatment and cosmetic care rather than hair-related services. Thus, the correct answer accurately reflects the wide-ranging practices and services involved in esthetics.
