Your dermis is the middle layer of skin in your body. It has many different purposes, including protecting your body from harm, supporting your epidermis, feeling different sensations and producing sweat and hair.
Your skin has three main layers, and the dermis (corium) is the middle layer of skin in your body. The other two layers of skin are your epidermis and hypodermis. Your dermis layer consists of two layers of its own.
Corium is another name for the dermis. Corium is a Latin word that means “leather” or “skin.”

Your dermis consists of two layers:
Your dermis and your epidermis are the top two layers of skin in your body. Your epidermis is the top layer, and your dermis is the middle layer. Your dermis exists between your epidermis and hypodermis.
Your epidermis is the thinnest layer of skin. It helps hydrate your body, produces new skin cells, protects your body from damage and makes melanin, which provides skin color.
While your epidermis is the thinnest layer of skin, your dermis is the thickest layer of skin. Your dermis contains collagen and elastin, which help make your dermis thick and supportive of your skin’s overall structure.
All of your connective tissues, nerve endings, sweat glands, oil glands and hair follicles exist in your dermis.
Each layer of your skin works together to protect your body. Your dermis has many additional functions, including:
