The study of skin histology specifically focuses on the structure and composition of skin tissue. This field examines the microscopic anatomy of the skin, including the various cell types, their arrangement, and how they contribute to the overall function and health of the skin. Understanding skin histology is crucial for estheticians as it helps them comprehend how different treatments and products interact with the skin on a cellular level, ultimately informing their practices and techniques.

The option related to the functions of living organisms is broader and does not specifically pertain to skin structure. While symptoms or signs of infection may be relevant to skin health, they do not encompass the detailed study of skin histology.

Thus, the emphasis in histology is clearly on understanding the skin's composition and its relation to overall skin health.
