How to keep your skin looking great

Skin has pigmentation, provided by melanocytes, which absorbs some of the potentially dangerous radiation in sunlight. It also contains DNA repair enzymes which reverse UV damage, and people who lack the genes for these enzymes suffer high rates of skin cancer. One form predominantly produced by UV light, malignant melanoma, is particularly invasive, causing it to spread quickly, and can often be deadly. Human skin pigmentation varies among populations in a striking manner. This has sometimes led to the classification of people on the basis of skin color. See the article on human skin color.

Blood capillaries are found beneath the epidermis, and are linked to an arteriole and a venule. Arterial shunt vessels may bypass the network in ears, the nose and fingertips.

The dermis lies below the epidermis and contains a number of structures including blood vessels, nerves, hair follicles, smooth muscle, glands and lymphatic tissue. It consists of loose connective tissue otherwise called areolar connective tissue - collagen, elastin and reticular fibres are present. Erector muscles, attached between the hair papilla and epidermis, can contract, resulting in the hair fibre pulled upright and consequentially goose bumps.

The main cell types of skin are fibroblasts, adipocytes (fat storage) and macrophages. Sebaceous glands are exocrine glands which produce sebum, a mixture of lipids and waxy substances: lubrication, water-proofing, softening and antibactericidal actions are among the many functions of sebum. Sweat glands open up via a duct onto the skin by a pore.

The constantly peeling off dead cells of the epidermis mix with the secretions of the sweat and sebaceous glands and the dust found on the skin to form a filthy layer on its surface. If not washed away the dirt and dead skin slurry begins to decompose emitting a foul smell.

The skin supports its own ecosystems of microorganisms, including yeasts and bacteria, which cannot be removed by any amount of cleaning. In general these organisms keep one another in check and are part of a healthy skin. When the balance is disturbed, e.g., by antibiotics which kill bacteria, there may be an overgrowth and infection by yeasts. The skin is continuous with the inner epithelial lining of the body at the orifices, each of which supports its own complement of flora.

Natural herbal diet pills Hoodia that stops the appetite

Hoodia is registered as a protected species to prevent Bio-Piracy but is allowed to be grown on a handful of commercial farms in South Africa owned by private farmers.

The Hoodia is an all-natural, herbal dietary supplement and there are no know adverse side effects relating to its use. No Caffeine. No Ephedra. So Hoodia is safe for us.

One of the active ingredients in the herb is a chemical compound called P57, which is thought to be at least partly responsible for the appetite-suppressing effects of hoodia gordonii. But this is probably an oversimplification, since herbs typically work with an assortment of chemical compounds, not just one chemical.

All over the world, people are trying to buy hoodia, and there just isn't enough supply to go around. The succulent growers have been wiped out. The seed providers have virtually no inventory left. And since hoodia takes more than six years to grow to harvesting height, there's going to continue to be a great hoodia shortage until at least 2010, maybe beyond.

Appetite suppressant medicine

During the holidays or when celebrating, many of us have overeaten. But some people have problems controlling their appetite and end up eating non-stop until eating is interrupted.

Binge eating can be triggered by many things such as stress, depression, loneliness or anger. Food is used as a way of dealing with issues other than hunger.

Many people are motivated to diet by wanting to be thin and attractive like the models we see everywhere - on TV and in magazines. What is far more important is that a leaner body reduces the risk for certain diseases.

Obesity often is viewed as the result of a lack of willpower, weakness, or a lifestyle "choice" - the choice to overeat and under exercise. The belief that persons choose to be obese adds to the hesitation of health professionals and patients to accept the use of long-term appetite suppressant medication treatment to manage obesity.
