FAQ
Frequently Asked Questions
No. 'Skin' refers to the entire organ (epidermis + dermis + hypodermis). 'Dermis' is specifically the middle, vascular, and connective tissue layer.
It would sound very technical and out of place. Use 'the layer under the skin' or simply 'skin' depending on context.
The epidermis is the outermost, protective, avascular layer of skin. The dermis is the inner, thicker layer containing blood vessels, nerves, glands, and hair follicles.
Generally uncountable when referring to the tissue layer (e.g., 'damage to the dermis'). It can be countable when referring to specific types or instances in comparative anatomy (e.g., 'the dermises of different mammals').
