How many times thicker is the dermis compared to the epidermis?

15 times

25 times

The correct answer is: 25 times

The dermis is approximately 25 times thicker than the epidermis. This significant difference in thickness is primarily due to the structural composition and functions of these two layers of the skin. The dermis is made up of dense connective tissue that provides strength and elasticity, housing critical components such as blood vessels, nerves, hair follicles, and glands. In contrast, the epidermis is a much thinner layer composed mainly of keratinized cells that serve as a barrier to protect underlying tissues from the environment. This substantial thickness disparity plays a vital role in the skin's functionality, as the dermis is responsible for supporting the epidermis and delivering necessary nutrients and oxygen through its blood vessels. Understanding this relationship between the two layers is essential for estheticians, as it informs their approach to various skin treatments and procedures.
