Inside: What is the Epidermis?

What is the epidermis layer of skin?

The epidermis is the outermost layer of the skin and protects the body from the environment. The thickness of the epidermis varies in different types of skin; it is only .05 mm thick on the eyelids and is 1.5 mm thick on the palms and the soles of the feet.

What is the function of each layer of the epidermis?

The outer layer of skin, the epidermis, provides waterproofing and serves as a barrier to infection. The middle layer of skin, the dermis, contains blood vessels, nerves, and glands that are important for our skin’s function. The inner layer of the skin, the subcutis, contains fat that protects us from trauma.

Needles of a tattoo machine punch between 50 and 3,000 times per minute through the epidermis, the outer layer of skin, and drive the ink into the dermis, the deeper layer that’s mottled with nerves and blood vessels. The rest of the dye gets soaked up by skin cells called fibroblasts.
Epidermis Definition

Are tattoos in the epidermis or dermis?

Tattoos are permanent images in the skin, delivered by needles injecting ink into the dermis. This tissue is just underneath the outer layer of your skin, called the epidermis. The ink is injected into the dermis by a machine. Then that delivers thousands of tiny pricks per minute via a needle.

Why is tattoo ink injected into the dermis?

The reason tattoo ink stays in the skin forever has to do with the immune system. When you get a tattoo, the ink flows down the tattooing needle into the middle layer of your skin, called the dermis. That creates a wound, which your body tries to heal by sending macrophages (a type of white blood cell) to the area.
