Dermatology encompasses the study of which of the following?

Dermatology is a specialized field of medicine that focuses on the diagnosis and treatment of skin disorders. This includes a wide range of conditions, from common issues like acne and eczema to more serious diseases such as psoriasis and skin cancer. Dermatologists are trained to understand the complex structures of the skin, as well as various skin diseases and their treatments.

The study of skin diseases and treatments is at the core of dermatology, emphasizing the importance of understanding skin health and conditions. Knowledge of the various treatments available—such as topical medications, systemic therapies, and laser treatments—is crucial for effective patient care in this field.

In contrast, while hair care routines are related to aesthetics and personal grooming, they do not fall under the medical study of dermatology. Nail structure is concerned with nail care and anatomy, primarily addressed in nail technology rather than dermatology. Body composition pertains to the physical makeup of the body and is not directly related to skin health or dermatological practices.
