Which feature(s) distinguish the subcutaneous layer from the epidermis and dermis?

The subcutaneous layer contains fat.

Explanation:

The terms mentioned in the question are the names of our skin's layers, epidermis, dermis and subcutaneous respectively.

Epidermis is the layer that is on the outer most which protects us against alien objects and diseases. Dermis is the layer under the epidermis and it contains things such as hair follicules, sweat glands etc.

The subcutaneous layer contains connective tissue as the epidermis so the most distinct feature that the subcutaneous layer has that allows us to differentiate it from the other layers is the fact that it contains fat.

I hope this answer helps.
