New Hampshire Cosmetology Practice Exam

The layer of skin known as the 'True skin' is the dermis, which lies beneath the outer layer of skin known as the epidermis. The cortex, while also a layer of skin, does not typically have the common name of 'True skin' and is not considered the correct answer. The subcutaneous tissue lies beneath the dermis and serves mostly as a layer of fat and insulation, so it is not the correct answer either. Overall, the dermis is the most accurate answer and is known as the 'True skin' because it contains important structures such as blood vessels, hair follicles, and sweat glands.
