Our Protective Barrier - Step 5 in our 8 Steps to Maintaining Moisture and Radiant Skin.
As the the largest organ of the body, our skin envelopes an average adult area of about 20 square feet and weighs commonly 6 to 8 pounds. With that much skin, It's understandable how crucial of a role it plays in defending our body.
And what's more remarkable about our skin is that it is created to protect us from the elements and many microbes (viruses and bacteria). It senses light, dark, heat, cold and touch. It also regulates our body's temperature.
Our skin creates Vitamin D in the epidermis as well. This important nutrient for the health of our bones is produced when our skin is exposed to sunlight. Although, only about 10 to 15 minutes in the sun a day is necessary for the skin to produce calcium and metabolize it.
Let's look at the 3 layers and that make up our "Super-Organ" structure:
* The Epidermis plays a key role in as the outermost layer of our skin. It is the outer layer that provides a waterproof barrier, also creating our skin tone.
* The Dermis is underneath the epidermis and contains hair follicles, connective tissue and sweat glands.
* And the Hypodermis is a connective tissue below the dermis, made of fat, and in which blood vessels and sebaceous glands run through.
Our "Fountain of Youth" comes from Collagen, which is the largest source of protein in the skin. It actually makes up 75% of our skin and wards off fine lines and wrinkles. As our skin is exposed to environmental factors and aging, loosing Vitamin C, the skin produces less collagen, diminishing a youthful appearance.
Keratin is the strongest protein in our skin. It is what gives strength and health to nails and hair.
The elastic protein called, Elastin resides in the dermis with collagen. It , like collagen, provides structure and elasticity to skin.
Melanin is produced by unique cells called melanocytes that live in the dermis. This creates the pigment of our skin, and is also responsible for darkening the skin when exposed to the sun,
Gaining an understanding of the Skin's Anatomy allows us to recognize the importance of maintaining a healthy lifestyle. Not only for a healthy outward appearance, but as our internal organ's defense shield.
