"We’re going to talk a little bit about aging skin, and into that aging skin we’re going to weave physiology of the skin, we’re going to weave skin care, and then we’re going to talk about some of the current theories and understandings that have to do with the body as a total organism, focusing on the most visible and largest organ of the body, which is your skin. I hope over the next hour or so we’ll be able to chat and have an understanding of exactly how to keep beautiful looking skin for a lifetime.
When I mention aging skin, most people have a visual image that comes to mind of wrinkled, unattractive skin, but dissecting down to the anatomy of the differences between younger skin and older skin is very important for your understanding of how to prevent skin aging.
The younger skin image that is shown in the left frame [in the video] basically shows a smooth surface with an excellent blood supply and a thick skin. The epidermis, which is shown in dark purple, overlies the dermis, which is shown in light purple. These are the two layers of the skin, the outer laying being the epidermis, and the inner layer being the dermis.
The dermis is a very important layer. It is the strength part of the skin. As a matter of fact, when you buy a leather handbag or a pair of shoes, it is the dermis of a cow that you are purchasing. The dermis has a structural integrity and strength of the skin. It’s an important layer because it contains not only the blood vessels, but it also contains the nerves.
Below the dermis is shown subcutaneous tissue, also known as the hypodermis. This is the fat. Abundant fat beneath the skin is very important because the fat provides a sort of cushion over which the skin drapes over the underlying muscles and bones.
In the right frame you see here the appearance of older skin. Notice how the skin is wrinkled. Notice how the epidermis is thinned and smooth. Notice how the dermis itself is also thinned. It is this thinning both of the epidermis and of the dermis that leads to the wrinkling of the skin. Notice also the presence of brown spots on the skin’s surface."
