Our skin is something we often take for granted. We may clean it, exfoliate it and occasionally moisturise it, but generally, we take our skin for granted... but did you know:
- It’s the largest organ of your body
- It would cover an area of approximately two square meters
- It accounts for approximately 15% of your body weight
- It is made up of three layers: epidermis, dermis and subcutaneous
- You have the same number of melanocytes as everyone else; your skin colour is due to their activity, not the quantity.
- It contains 11 miles of blood vessels
Why caring for your skin is essential
We often say that we know something as well we as know the back of our hand. Our skin is something we very much take for granted, we may notice a new wrinkle or a monster pimple, but on the whole we barely notice our skin at all. Despite our negligence our skin plays some fundamental roles in our general well-being.
Your skin provides a barrier to harmful environmental aggressors like germs and UV radiation. The skin's slightly acid surface is essential in preventing bacteria attacks which can cause irritation and infection. Even our skin’s ability to “tan” (increased melanin production) is a system designed to protect us from UV radiation.
Our skin cells need water, yet if the surface of our skin (and the walls of our skin cells themselves) did not have a “waterproofing” effect, all the water in our skin would evaporate and the cells would die. The outermost layer of skin is made up of keratin, which likes oils much more than it likes water acting as a protective waterproof barrier.
While the outermost layer of skin is designed to repel water, it can also selectively absorb oily substances that are small enough to penetrate in between the cells. Technically speaking, the keratin creates a semi-permeable membrane. This is why skincare products with small molecules can penetrate the skin while others sit on the surface.
Nerves in the skin respond to different stimuli, including touch, pain, pressure and temperature by passing along information to the central nervous system.
Your skin regulates your body temperature. When we're hot, our skin can cool our entire bodies by sweating and also increasing blood flow, which allows heat to be lost through the skin. In contrast, when we're cold, the diameter of our blood vessels decreases, which reduces blood flow, retaining heat in the body.
Complex chemical reactions are constantly going on in our skin to keep cells regenerating, repairing damage and even converting sunlight into Vitamin D.
