What does the study of skin histology focus on?

  1. Functions of living organisms

  2. Structure and composition of the skin tissue

  3. Symptoms or signs of infection

  4. Material with openings

The correct answer is: Functions of living organisms

The study of skin histology focuses on the structure and composition of the skin tissue. Histology is the microscopic study of tissue appearance, organization, and function on a very small scale. It involves examining the cells and any intercellular substances within the skin to better understand its composition and structure. This knowledge is crucial for estheticians, as it helps them understand how different skincare products and treatments can interact with the skin on a cellular level.
