Anti-Aging skin: Basic scientific information you need to be able to evaluate products before buying them.
Human skin is one of the most elastic, sensitive and durable products on earth. The skin covering your body is the largest of you organs. Yes, science classifies it as an organ. If you could take it off and spread it out,it would cover about 20 square feet!
All Human skin is made in three layers. The outermost layer is the epidermis. Next comes the dermis and the innermost layer is called the hypodermis
Information: The Epidermis
When you look in the mirror or run you hand across your skin, interesting is that the epidermis itself is made up of different layers of cells.
First there is keratin. Keratin is a protein that is hard. It is what keeps your skin from getting water logged when you put your hands in water or go for a swim. The other major cells in the epidermis are called melanocyters. The melanocyters produce the melatonin whichi is what gives your skin pigmentation (color).
Your epidermis sheds dead skin cells. The cells in your skin move to the surface (the epidermis). They die and slough off. Sometimes you might see small flakes of skin cells on your bedding or on a dark piece of clothing that was next to your skin all day.
By the time you have reached age 70, you will have shed some 40 pounds of skin cells. John. J Medina, the author of The Clock of Ages notes that 75% of human household dust is dead skin cells!
What is most important to remember about the epidermis is that it is made up of proteins: Keratin, which makes it waterproof, and melanocyters which affects your skin color.
The layer under the epidermis is called the dermis. This layer is what gives your skins its ability to stretch, to be elastic (return to place after stretching) and to remain strong.
Your dermis contains the proteins collagen and elastin. Collagen gives your skin its strength and form. Elastin are the proteins that give your skin its elasticity.
To review: Your epidermis provides your individual skin color and it makes your skin waterproof.Your dermis which is the next layer down, gives your skin its elasticity and its strength. You can pinch your skin and it will not fall off. And it will return to its original shape when you stop pinching it.
The third and last layer of your skin is called the hypodermis. Your hypodermis is composed mostly of fat cells. They act as a sort of anchor for the rest of your skin layers. Your hypodermis also includes nerve fibers that allow your skin to be so sensitive to touch.
Fibres from your dermis (the second layer) extend down through your hypodermis and attach to your muscles and blood vessels. And so your skin stays attached to the rest of your body.
Sweat glands. In addition to the proteins, there are sweat glands, hair folicies and sebaceous glands through out the three layers of your skin. Their purpose is to bring oils to the surface of your skin.
As we age there are changes to these three layers of skin and these changes can affect our appearance.
So that is it. That is the basic science for understanding Anti-aging skin care. AND there is GOOD NEWS for those of us living in this century...
