What is the term for skin's ability to take in substances through cells and tissues?

  1. Sensation

  2. Absorption

  3. Excretion

  4. Secretion

The correct answer is: Sensation

The correct term for the skin's ability to take in substances through cells and tissues is absorption. Absorption refers to the process in which substances penetrate the skin and are taken in by the cells and tissues. This is a crucial concept in esthetics as many skincare products are designed to be absorbed by the skin to provide benefits such as hydration, nourishment, and treatment of various skin conditions. Sensation, excretion, and secretion are different processes that do not specifically refer to the skin's ability to take in substances through cells and tissues.
