People with acne at least aren't alone in their suffering: about 80% of the population will face the problem between the ages of 12-25.


In the area of the face and neck, skin pores serve as openings to specialized clusters of cells called sebaceous glands. These glands secrete a waxy substance known as sebum, some of which is needed to help keep the skin from losing too much water and drying out.
As people reach puberty, certain hormones in their bodies cause these glands to grow in size and become too active. The surplus sebum they produce clogs the pores. When mixed with the bacteria normally found on the skin and in the glands, this waxy debris can "flare up", causing a pimple.
Heredity plays a significant role in determining who will have problem skin- and this, of course, is something you can't control.
Other factors that aren't tied to bloodiness include climate (particularly the hot and humid climate), stress, and the hormonal changes associated with menstruation. A number of drugs are also known to bring on attacks of acne.
Where diet is concerned, there is no scientific proof that certain foods have any impact. However, if you notice that some of the things you eat seem to make the condition worse, it makes sense to avoid them and get your nutrition from alternatives.


Though most cases of acne tend to clear up eventually on their own, it is estimated that 350,000 Americans seek medical treatment of the disorder each year. The common goal of therapy is to prevent scarring and minimize further outbreaks. General measures are aimed at keeping the skin clean and allowing the pores to drain.
Good hygiene helps a lot to control mild cases of acne, but effective treatment of more severe cases may call for stronger measures.
1. Benzoyl peroxide: this is the active ingredient of many popular nonprescription products. In addition to killing bacteria and reducing fatty acids on the skin, they also cause a fine peeling of the skin, thus reducing blemishes.
2. Sulphur products: are antibacterial medications available in many dosage forms without prescription.
3. Tretinoin: is a new prescription medication that works like benzoyl peroxide, but is stronger and may cause more irritation to the skin. Patients using tretinoin should avoid excessive sunlight and ultraviolet lamps. Cold weather and wind may also increasesensitivity to the medication.
4. Antibiotics: such as tetracycline, clindamycin, and erythromycin are sometimes used to treat moderate to severe acne. They are available on prescription in either oral or topical forms.
5. Isotretinoin: use of this prescription product can dramatically improve severe acne, but side effects are common: dry skin and mouth, stiffness and soreness, and conjunctivitis among them. Because it has been linked to birth defects, it should never be used by women who are or plan soon to become pregnant.

In general, if you have an acne prone skin, you should remember the follwing:
Wash your face two or three times daily with soap and water. But be gentle about it-vigorous scrubbing can make the condition worse. And it's better to blot dry than wipe.
Avoid the use of oily and greasy cosmetics. If you're going to wear makeup, make sure it's water based.
Don't rub or pick at the skin. And avoid wearing clothing-for example, chin straps and headbands-that has tendency to rub against the skin.
Whichever acne treatment you use, it is important to remember that more is not necessarily faster or better. And, of course, always carefully wash the skin prior to applying any medication.

Using mouthwash, gum, or mint candies to 'treat' bad breath is like using perfume to cover up body odor. They won't solve the problem, at least not for long.
There are many causes of bad breath, including sinus infections, and stomach ulcers. Another major source of bad breath is the teeth & gums.
If you let bacteria build up in your mouth, you'll get bad breath as the bacteria rot leftover foof particles like they rot leftover foods in your garbage can.
Unfortunately, most people don't realize they have bad breath unless friends/relatives clue them in. Instead of waiting for the word, here are some precautions that will be good for your teeth as well as you breath:

*Brush and floss after every meal. Brush your teeth for several minutes. Brush the top of your tongue too.
*Using toothpaste with baking soda. It makes the acid level in your mouth less hospitable to bacteria.
*If you have dentures, clean them well every day and rinse your mouth thoroungly before re-inserting them.
*If you have an infection or ulcer in or on your mouth, gums,tongue, rinse out your mouth with an antiseptic mouthwash for a few days.
*Have a dental checkup at least once a year.
In addition to a clean mouth, there are several ways you can lessen bad breath:
*Stop smoking; eat breakfast; quench your thirst with water instead of coffee, tea, soft drinks, or alcohol, which can leave a residue in your mouth, causing bad breath; finish each meal with a drink of water or by rinsing your mouth; avoid garlic & onions; eat plaque-fighting foods such as carrots, peanuts, low-fat cheese, and celery, these foods not only fight plaque but possibly mouth odors as well; and avoid dryness in the mouth.
If you still have bad breath after following above instructions, it's time to see a doctor &/or dentist.
