What position does a client assume when they are in a supine position?

When a client is in a supine position, they are lying flat on their back, which means that their face is directed upward. This position is commonly used in various treatments such as facials, massages, and other spa services, as it allows for easy access to the face and upper body.

This position provides maximum comfort and is particularly beneficial for esthetic procedures where the face is the primary focus. In contrast, the other options describe different orientations: face down (prone), side lying (lateral), and seated, which do not align with the definition of the supine position. Understanding body positions, including supine, is essential for effective treatment planning and ensuring the safety and comfort of clients during esthetic procedures.
