The epidermis is the outermost layer of skin, providing a waterproof barrier and contributing to skin tone. It acts as a protective shield against the external environment.
The dermis, located beneath the epidermis, contains connective tissue, hair follicles, blood vessels, lymphatic vessels, and sweat glands. It supports the epidermis and helps regulate temperature.
The hypodermis is the deepest layer of skin, composed primarily of fat and connective tissue. It acts as an insulator, protects internal organs, and stores energy.
Therefore, the epidermis, dermis, and hypodermis all contribute to protecting the skin.
