Skin is the largest organ of the human body, made up of water, protein, fats, and minerals. It has three main layers: the epidermis, dermis, and hypodermis.

 

The epidermis:  is the top layer of skin that acts as a protective barrier against bacteria and germs, makes new skin cells, protects your body from external elements like rain and sun, and provides skin color.

 

The dermis:  is the middle layer of skin that makes up 90% of the skin’s thickness. It contains collagen and elastin proteins that make skin cells strong and resilient. The dermis also grows hair, keeps you in touch with your surroundings through nerve receptors, produces oil to keep the skin soft and smooth, and releases sweat through skin pores.

 

The hypodermis: is the bottom layer or fatty layer that attaches the skin to underlying bone and muscle tissue.
