What are the Functions of Our Skin?

Our skin is the largest organ in our body, and every week we’re sharing different tips on how to take care of it! But, what exactly does our skin do for us? Below we share the five major functions of our skin.

Protection

The skin has many roles in the body, but its number one function is to be part of the integumentary system (that's Int-egg-you-ment-arry, fyi). This system protects internal organs (heart, lungs, liver, etc.) from injury and infection. Keratin, a protein that is a major component in outer layer of our skin cells, stops harmful germs from invading our bodies.

The skin’s elasticity withstands physical pressure and reduces injuries. The epidermis (the outermost layer of our skin) forms the protective covering of the skin and serves as a barrier to keep out sunlight, germs, heat, cold, dirt and gases while keeping in water, blood, minerals, vitamins, hormones and proteins.

Regulation

The skin allows us to regulate our body temperature via sweat. Why is this important?  Once the body temperature rises to a certain level, sweat glands are activated which then pour out onto the surface of the skin where it evaporates, causing the skin and internal core to cool. If outside humidity prevents this evaporation, serious illness can result - which is why running is usually not advised on hot, humid days!

Excretion

Your skin also plays a role in the body's excretory system. Before you say "Ew!!" remember that this allows for the excretion of unwanted toxins thorough the sweat glands. Buh-bye bad stuff! 

Sensation

Your skin is a sensory organ. Nerve endings in the epidermis (the outermost layer of our skin) allow us to respond to heat, cold, touch, pressure, pain and location. Just like sight and hearing, without this essential sense - we'd be lost!

Storage

The skin stores Vitamin D. Vitamin D is created by your body, but only after the skin has been exposed to sufficient sunlight. Vitamin D is necessary to absorb calcium and promote bone growth.

We hope this will motivate you to take care of your skin, starting with a proper skin care routine.
