Natural Skin- Understanding The Anatomy Of The Skin

To understand natural skin, it is important to know how your skin functions. The skin is the human body’s biggest organ, is roughly divided into 3 layers: The Epidermis (the outer and top layer). The Dermis (the middle layer) The Hypodermis (Subcutaneous Tissues). There is a glue-like area called the basements membrane which combined the epidermis to the dermis.

The Epidermis:

The outer exposed epidermis layer has many functions; it protects the body against environmental pathogens, reducing infection and assists regulated water loss from the body. It is the part of the skin we see that enables us to determine the beneficial effect of our skincare routine.

Epidermis Structure:

The structure of the epidermis consists of four main layers, these are:

  • stratum-corneum
  • stratum-granulosum
  • stratum-spinosum
  • stratum-basale

However, in areas of hard skin like the palm of your hands or sole of feet, there is a fifth layer called the stratum lucidum.

There different types of cells in the epidermis:

The Epidermis is comprised of three cell types and each ofthese play an important function.

  • Keratinocytes – the most common type of skin cells and are responsible for making keratin,
  • Melanocytes – these are responsible for the production of the pigment melanin which gives skin a tan and protects the skin from ultraviolet light damage.
  • Langerhans cells- these are a key for the body’s immune defence system.

Natural skin and the journey of your skincare product through the epidermis:

It takes around four weeks for the epidermis to be completely replaced. A keratinocyte cell begins as thick and plump within the stratum-basale and as it travels through the layers become flat and flakes off at the stratum- corneum. When using skin care products, if irritation does not occur, it is important to give it 4 weeks. This will enable you to see the full effect of the product on your skin.

The Dermis:

The Dermis contains specialised cells called fibroblasts which are responsible for the production of collagen. The dermis is the largest layer of the skin. It contains important structures. These structures include hairs, sensory nerve endings blood vessels, lymph vessels, sweat glands and ducts, and sebaceous glands.

The Hypodermis:

The bottom Hypodermis layer of the skin contains collagen and fat cells called adipocytes. The Hypodermis has many functions including; energy storage, production of leptin hormone,  body temperature regulation, and insulation.

Natural skin and natural  beauty products:

These three main layers of the skin form a multi-functional organ that protects us. If you are planning on making a change to natural beauty ingredient skincare, remember to give it time (at least 4 weeks if irritation does not occur). Natural beauty products have many benefits including; the limitation of irritation, no nasty side effects from unknown chemicals, and gentle on your skin. It is important to treat your well and only use the best of products to prevent premature aging and illness.
