Is hyperdermis a layer of the skin?

The term "hyperdermis" is not commonly used in anatomy; however, it may refer to the hypodermis, which is the layer beneath the dermis of the skin. The hypodermis, also known as subcutaneous tissue, primarily consists of fat and connective tissue, providing insulation and cushioning for the body. It helps anchor the skin to underlying structures, such as muscles and bones, but is not technically a layer of the skin itself.
