What's in Your Skin Care Cream

The skin care industry has the public convinced that their products will bring you a glowing complexion, reduce wrinkles and reduce discoloration. However, the cosmetic industry is not regulated and so long as they list the ingredients on the bottle as required by the FDA they can make all the claims they like. Additionally, many skin care companies use the term Naturally when in reality many products contain less than 1% of a natural ingredient such as aloe Vera, or other essential oils.

In reality many cosmetics and baby products contain harmful ingredients which are detrimental to your health or your babies. The United Nations Environmental Program estimates that approximately 70,000 chemicals are in common use across the world with 1,000 new chemicals being introduced every year. Of all the chemicals used in cosmetics, the National Institute of Occupational Safety and Health has reported that nearly 900 are toxic - although other groups attack that figure as being far too conservative.

Below are a few guidelines when selecting a skin care product.

Talc is commonly used to dry, freshen and deodorize the skin. It is a mineral consisting of hydrated magnesium silicate. Research has suggested that women who use talcum powder for personal hygiene between their legs are more likely to get ovarian cancer. It is thought that talc may travel up into the vagina, through the cervix into the womb, along the fallopian tubes, to the ovaries, causing irritation and inflammation, resulting in cancerous changes. Additionally, inhalation of talc may irritate the respiratory system.

Triclosan is an antimicrobial chemical found in hand washes, toothpastes and household products; it may kill 'friendly bacteria' which help with digestion and protect the body from more serious infection. There is cause for concern that the overuse of anti-bacterial products inhibits the normal process of the immune system to ward off germs.

Phthalates is used to make plastics flexible, they are found in shampoos, moisturizers, nail polishes and hair sprays. Animal studies have suggested links with testicular abnormalities in male offspring exposed to these chemicals in the womb. Phthalates like all chemical processed ingredients in cosmetics are absorbed through the skin or inhaled.

Sodium laurel sulphate was originally used as an industrial degreasing; it is widely used in shampoos, bubble baths and other washing products to product foam. This chemical can irritate eyes, skin and mouth.

Aluminums salts (eg: aluminum chlorohydrate) is used in antiperspirants and deodorants, they dissolve onto the skin to create a coating over sweat glands and so reduce the amount of sweat that is released. There have been concerns that this chemical may be related to breast cancer.

Parabens (eg: methylparaben (E218), ethylparaben (E214)) are used as preservatives in cosmetics, food and household products, they may mimic the female hormone, estrogen. Concerns focus on a possible link to breast cancer, when used in deodorants.

About Your Skin

Quick! What's the biggest organ in your body?

You might be surprised to find out it's the skin, which you might not think of as an organ. No matter how you think of it, your skin is very important. It covers and protects everything inside your body. Without skin, people's muscles, bones, and organs would be hanging out all over the place. Skin holds everything together.

It also:

1. protects our bodies
2. helps keep our bodies at just the right temperature
3. allows us to have the sense of touch

Don't Miss Your Epidermis

The skin is made up of three layers, each with its own important parts. The layer on the outside is called the epidermis (say: eh-pih-dur-mis). The epidermis is the part of your skin you can see.

Look down at your hands for a minute. Even though you can't see anything happening, your epidermis is hard at work. At the bottom of the epidermis, new skin cells are forming.When the cells are ready, they start moving toward the top of your epidermis. This trip takes about 2 weeks to a month. As newer cells continue to move up, older cells near the top die and rise to the surface of your skin. What you see on your hands (and everywhere else on your body) are really dead skin cells.
These old cells are tough and strong, just right for covering your body and protecting it. But they only stick around for a little while. Soon, they'll flake off. Though you can't see it happening, every minute of the day we lose about 30,000 to 40,000 dead skin cells off the surface of our skin. So just in the time it took you to read this far, you've probably lost about 40,000 cells.

That's almost 9 pounds (4 kilograms) of cells every year! But don't think your skin might wear out someday. Your epidermis is always making new skin cells that rise to the top to replace the old ones. Most of the cells in your epidermis (95%) work to make new skin cells. And what about the other 5%? They make a substance called melanin (say: mel-uh-nun). Melanin gives skin its color. The darker your skin is, the more melanin you have. When you go out into the sun, these cells make extra melanin to protect you from getting burned by the sun's ultraviolet, or UV, rays.
That's why your skin gets tan if you spend a lot of time in the sun. But even though melanin is mighty, it can't shield you all by itself. You'll want to wear sunscreen and protective clothing, such as a hat, to prevent painful sunburns. Protecting your skin now also can help prevent skin cancer when you get older.

The Dermis Is Under the Epidermis

The next layer down is the dermis (say: dur-mis). You can't see your dermis because it's hidden under your epidermis. The dermis contains nerve endings, blood vessels, oil glands,and sweat glands. It also contains collagen and elastin, which are tough and stretchy. The nerve endings in your dermis tell you how things feel when you touch them. They work with your brain and nervous system, so that your brain gets the message about what you're touching. Is it the soft fur of a cat or the rough surface of your skateboard? Sometimes what you feel is dangerous, so the nerve endings work with your muscles to keep you from getting hurt. If you touch something hot, the nerve endings in your dermis respond right away: "Ouch! That's hot!" The nerves quickly send this message to the brain or spinal cord, which then immediately commands the muscles to take your hand away. This all happens in a split second, without you ever thinking about it. Your dermis is also full of tiny blood vessels. These keep your skin cells healthy by bringing them the oxygen and nutrients they need and by taking away waste. These blood vessels are hard to see in kids, but you might get a better look if you check out your grandparents' skin. As the dermis gets older, it gets thinner and easier to see through. The dermis is home to the oil glands, too. These are also called sebaceous (say: sih-bay-shus) glands, and they are always producing sebum (say: see-bum). Sebum is your skin's own natural oil. It rises to the surface of your epidermis to keep your skin lubricated and protected. It also makes your skin waterproof — as long as sebum's on the
scene, your skin won't absorb water and get soggy. You also have sweat glands on your epidermis. Even though you can't feel it, you actually sweat a tiny bit all the time. The sweat comes up through pores (say: pors), 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 Layer Is Subcutaneous Fat

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: fah-lih-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 100,000 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.

Skin Can Warm and Cool You

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 98.6° Fahrenheit (37° Celsius) to keep you and your cells healthy. 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. The hotter you are, the more sweat your glands make! Once the sweat hits the air, it evaporates (this means that it changes from a liquid to a vapor) off your skin, and you cool down. What about when you're ice-skating or sledding? When you're cold, your blood vessels keep. your body from losing heat by narrowing as much as possible and keeping the warm blood away from the skin's surface. You might notice tiny bumps on your skin. Most kids call these goosebumps, but the fancy name for them is the pilomotor (say: py-lo-mo-ter) reflex. The reflex makes special tiny muscles called the erector pili (say: ee-rek-tur pie-lie) muscles pull on your hairs so they stand up very straight.
