Our skin holds our body together, regulates our body temperature through sweat and gives us the sense of touch and pain.
What exactly makes up our skin structure? Made up of 3 layers, the top layer is called the epidermis, followed by the dermis and then the subcutaneous layer.
Each of these has their own functions.
The epidermis is the outer layer of the skin.
The topmost layer of the epidermis is made up of dead skin cells which will be shed off every 3-4 weeks and be replaced by the lower layer of new cells from below which are gradually pushed upwards.
The second layer is called the dermis, a complex tissue framework consisting of our blood vessels, sweat glands, oil glands, nerves, hair follicles and skin tissues like collagen and elastin are found.
The blood vessels carry oxygen to other parts of our body while the oil glands produce sebum which rises to the surface and lubricate the skin.
The extensive network of nerves protects us by sending signals to our brain to help us detect pain, temperature, texture and pressure.
The collagen and elastin are proteins that help to maintain the skin's firmness and elasticity.
The subcutaneous tissue is the last layer.
Made up of fats and collagen, this layer is important as it stores energy and nutrients.
It keeps the body warm and protects the body from injuries.
Our skin is a complicated organ with various functions.
Rashes, infections and irritations will result if any of the structures in the skin are not working properly.
