In cosmetology, the specialty that requires knowledge of human anatomy is **dermatology**. Dermatology involves the study of the skin, hair, and nails, which are all part of the human body's anatomy.
Understanding human anatomy is crucial in dermatology because the skin is the body's largest organ and plays a vital role in protecting our internal organs. By knowing the structure and functions of the skin, a dermatologist can diagnose and treat various skin conditions and diseases effectively.
To excel in dermatology, one must have a solid foundation in human anatomy to comprehend how different skin conditions manifest, the underlying causes, and how treatments can affect the skin's health and appearance.
