How thick is your skin?

How thick is your skin?

And no I'm not talking about the age-old idiom here that leads into a rant about energetic boundaries, although that's not a bad topic.

Today, I'm discussing the actual physiology of your SKIN.

As you may or may not know, many skincare products and cosmetics are full of hormone disruptors, unnatural fillers, toxic chemicals, heavy metals and nasty preservatives with  harmful side effects to both skin and body.

*Gasp* These should be banned and regulated, right?

RIGHT. But they're not, so it goes without saying that you have to pay attention to what you put on and into your body...it greatly impacts the condition of your skin–and your health. 

To better understand how topical products affect your skin, let’s look at its form and function.

The skin is the body’s largest organ and is responsible for:

  • Regulating body temperature
  • Acting as a protective layer against the environment, toxins, UV & bacteria, etc.
  • Eliminating toxins  
  • Recognizing and removing foreign bodies
  • Providing warning signals for pain and injury
  • Protecting from infection
  • Water-proofing
  • Making up part of our immune system (i.e. healthy balance of bacteria on the skin)
  • Feeling touch and physical sensations touch 

 The skin is roughly divided into three layers: epidermis, dermis and hypodermis.


The epidermis is the outer top layer that you see and consists of three different types of cells: Keratinocytes, Melanocytes and Langerhans cells creating a principal part of the immune defense system. These dermal cells collectively block toxins and pathogens from the body, prevent loss of moisture and heat, make pigment, and carry out foreign matter to other parts of the body–like lymph nodes where it's processed and eliminated.  

 The body is pretty smart isn't it?

It takes around 4 weeks for the epidermis to be completely replaced although this process slows down with age.  

The dermis that lies between the epidermis and hypodermis, is the main part of the skin, consisting of connective tissue housing structures of blood vessels, lymph vessels, sensory nerve endings, sweat glands, hairs and sebaceous glands that produce sebum (your own natural oil). 

The hypodermis (aka subcutaneous fat) is the deepest and thickest layer of the skin that is in between the dermis (above) and the fascia tissue (below). This layer contains coarse bundles of collagen and is mainly composed of fat cells. The main functions are energy reserves from fat stored in the tissue, insulation, padding to prevent injury to underlying muscles and the physical appearance of skin.

So back to how thick is your skin? 

Skin varies from 0.05 mm (on thinnest skin like eyelids & behind the ears) up to 1.5 mm thick (on palms and soles of the feet). Male skin is typically thicker than female skin.

The skin changes over time depending on age, exposure, seasons, injury, microbes and how it's cared for. 

Remember...

Your skin is a sensual, multi-functioning organ that is incredibly important. Everything that you apply topically affects your skin and your health.

The question is how are your products impacting your skin?
