Detailed explanation-2: -Your skin has three main layers, and the epidermis (ep-uh-derm-us) is the outermost layer in your body. The other two layers of skin are the dermis and hypodermis.

Detailed explanation-3: -As the deepest layer, hypodermis is often defined as the foundation of human skin and primarily consists of connective tissues and adipose. The connective tissues are made of collagen proteins and elastin, and are vital to the role of hypodermis in supporting the upper layers.
