The inflammatory skin diseases psoriasis and atopic dermatitis also show decreased barrier function, but the underlying mechanisms remain under investigation.
Topically applied "moisturizers" work by acting as humectants or by providing an artificial barrier to trans-epidermal water loss; current work has focused on developing a more physiologic mix of lipids for topical application to skin. Recent studies in genetically engineered mice have suggested an unexpected role for tight junctions in epidermal barrier function and further developments in this area are expected.
Ultimately, more sophisticated understanding of epidermal barrier function will lead to more rational therapy of a host of skin conditions in which the barrier is impaired. You also have sweat glands in your dermis. Even though you can't feel it, you actually sweat a tiny bit all the time. The sweat comes up through pores , tiny holes in the skin that allow it to escape. When the sebum meets the sweat, they form a protective film that's a bit sticky. An easy way to see this film in action is to pick up a pin with your fingers. Then wash your hands well with soap and water and dry them off completely.
Now try to pick up that pin again. It won't be so easy because your sticky layer is gone! Don't worry — it will be back soon, as your sebaceous and sweat glands create more sticky stuff.
The third and bottom layer of the skin is called the subcutaneous say: sub-kyoo-TAY-nee-us layer. It is made mostly of fat and helps your body stay warm and absorb shocks, like if you bang into something or fall down. The subcutaneous layer also helps hold your skin to all the tissues underneath it. This layer is where you'll find the start of hair, too. Each hair on your body grows out of a tiny tube in the skin called a follicle say: FAHL-ih-kul.
Every follicle has its roots way down in the subcutaneous layer and continues up through the dermis.
You have hair follicles all over your body, except on your lips, the palms of your hands, and the soles of your feet. And you have more hair follicles in some places than in others — there are more than , follicles on your head alone! Your hair follicles rely on your sebaceous glands to bring on the shine. Connected to each follicle in the dermis layer is a tiny sebaceous gland that releases sebum onto the hair.
This lightly coats the hair with oil, giving it some shine and a little waterproofing. Your skin can help if you're feeling too hot or too cold. Your blood vessels, hair, and sweat glands cooperate to keep your body at just the right temperature. If you were to run around in the heat, you could get overheated.
If you play outside when it's cold, your inner temperature could drop. Either way, your skin can help. Your body is pretty smart. It knows how to keep your temperature right around Your skin can respond to messages sent out by your hypothalamus say: hy-po-THAL-uh-mus , the brain's inner thermometer. If you've been running around on a hot day, your blood vessels get the signal from the hypothalamus to release some of your body's heat. They do this by bringing warm blood closer to the surface of your skin.
That's why you sometimes get a red face when you run around. To cool you down, sweat glands also swing into action by making lots of sweat to release body heat into the air.
