The first unit of the Point of Care Ultrasound course in Aesthetic Medicine focuses on facial ultrasound, covering physics, quality control, and the application of the B-mode technique. It emphasizes understanding how ultrasound waves interact with different structures in the body, the importance of high-frequency linear ultrasound probes, and recognizing artifacts in ultrasound imaging.

The first unit of the point of care ultrasound course in aesthetic medicine focuses on facial ultrasound, covering physics, quality control, and the application of the beo technique. Understanding how ultrasound waves interact with different structures like fillers and threads is crucial for accurate imaging.

The chapter discusses the importance of using a linear ultrasound probe for facial aesthetics, emphasizing the use of B mode for initial assessment followed by color and spectral imaging. It covers the layers of skin, subcutaneous fat, muscle, and nerves visible through ultrasound imaging, highlighting the significance of proper probe orientation for accurate visualization.
