Causes\nThe precise pathogenesis of rosacea still remains unknown, but most experts believe that rosacea is a disorder where the blood vessels become damaged when repeatedly dilated by stimuli. The damage causes the vessels to dilate too easily and stay dilated for longer periods of time or remain permanently dilated, resulting in flushing and redness. Immune cells and inflammatory mediators can leak from the microvascular bed causing inflammatory pustules and papules, especially with those with papulopustular rosacea.\n\nRosacea has a hereditary component and those that are fair-skinned of European or Celtic ancestry have a higher genetic predisposition to developing it. Women are more commonly affected but when men develop rosacea it tends to be more severe. People of all ages can get rosacea but there is a higher instance in the 30-50 age group. The first signs of rosacea are said to be persisting redness due to exercise, changes in temperature, and cleansing.\n\nTriggers that cause episodes of flushing and blushing play a part in the development of rosacea. Exposure to temperature extremes can cause the face to become flushed as well as strenuous exercise, heat from sunlight, severe sunburn, stress, cold wind, moving to a warm or hot environment from a cold one such as heated shops and offices during the winter. There are also some foods and drinks that can trigger flushing, these include alcohol, foods high in histamine and spicy food.\n\nCertain medications and topical irritants can quickly progress rosacea. If redness persists after using a treatment then it should be stopped immediately. Some acne and wrinkle treatments that have been reported to cause rosacea include microdermabrasion, chemical peels, high dosages of isotretinoin, benzoyl peroxide and tretinoin. Steroid induced rosacea is the term given to rosacea caused by the use of topical or nasal steroids. These steroids are often prescribed for seborrheic dermatitis. Dosage should be slowly decreased and not immediately stopped to avoid a flare up.\n\nStudies of rosacea and demodex mites have revealed that some people with rosacea have increased numbers of the mite, especially those with steroid induced rosacea. When large numbers are present they may play a role along with other triggers.

I have heard of that before.  Like your body breaks out from your partners secretions.  I think your doctor or dermatologist would be a good place to start because the web didn't bring anything up but it was on news and I saw it.

How come people show concern about it this much?  Like some other person said, for a big number of the world male population this is normal.  I think this is one of the things that have been recorded on people's mind, I swear.  Why there is not a lot of repulsion toward the female reproductive organ.  As I see it, there are more opportunities for it to be of concern.  A lot more of skin goin this way and the other.  A cavity for breeding of all kind of nasties.  But you know, I am not concerned, because I was not taught in that belief (maybe I should)

What Kind Of Emotions Are Associated With Blushing?\n\nGenerally blushing is associated with a feeling of inferiority.\n\nIt is important to note that a part of the mind may know that this feeling is totally illogical and yet a part may still feel a sense of being inferior.\n\nFrom this, it is highly probable that blushing occurs as some evolutionary mechanism whereby in a social interaction, one shows submission to the other more dominant party. Looking at the animal kingdom, there is certainly precedence for this kind of signaling mechanism. Especially where in a tribe situation, there would be one dominant male, called the alpha male. Showing submission in a possibly threatening situation, may well result in survival for the non alpha male.\n\nThe problem is that this mechanism is no longer relevant to our modern society.

Rosacea is caused by the enlargement of tiny blood vessles under the skin.  You can get that treated with a laser at just about any Cosmetic Surgery place.\n\nIf you have chronic dry skin, I would also suggest moving to a part of the country that is more humid, such as the east coast of TX, or anywhere on the east coast of the country.

this is called rosacea, it is a chronic inflammatory congestion of the cheeks and nose. It is characterized by redness, dilation of the blood vessels, and the formation of papules. The causes of rosacea is unknown.  Certain thinks are known to aggravate in some individuals.  These include consumption of hot liquids, spicy foods or alcohol, being exposed to extremes of heat and cold, exposure to sunlight, and stress.

The reason the plant makes urushiol, the chemical that causes the reaction, is to protect itself from herbivores- Plants cant run or fight back, so they use chemical warfare.\n\nUrishiol penetrates the outer layer of skin until it hits the dermis, and in the dermis an allergic reaction to the urushiol occurs.\n\nIt takes a few hours to a day to get the reaction, and can last a week- In some, it's a massive allergic response that causes pain, itching, swelling, formation of large blisters and pustules that ooze pus-it can even scar the skin

My son had a similar condition last year at school. The nurse at school called me and apparently it is called " Fifth disease". It went away within 2 days,  it was splotchy, red, no itch, no fever, no residual side effects, but he looked horrible for 2 days, it affected his cheeks, arms, thighs, buttocks, back and stomach it  has never come back, I have never heard of anything like this being a recurring problem. Best wishes, Tiff

For the last 20 years, antibiotic tablets (such as tetracycline) have been the main treatment for Rosacea. These are generally taken two to four times a day for the first three to four weeks. The dose will then be gradually reduced. Treatment will probably continue for at least three months.\n\nA topical gel or cream (containing metronidazole) that is applied directly to the affected skin, has recently been proven to be as effective as oral antibiotics, without the problems associated with taking tablets, such as thrush or stomach upsets. Metronidazole gels or creams are made by different companies and sometimes you may have a problem with skin irritation using a particular brand. If this is the case, it is worth asking to swap to another brand.\n\nAlthough antibiotics are used in the treatment of Rosacea, those most commonly prescribed belong to a group of tetracyclines such as oxytetracycline, lymecycline or minocycline. They work by reducing the bacteria on the skin and reducing the inflammation in the blood vessels in the face. This may sometimes help with reducing redness. Tetracyclines can be very effective in treating ocular Rosacea (see section below) as they reduce the inflammation of the small blood vessels of the eyes.\n\nSteroid creams were once used to treat Rosacea, but are no longer recommended. In fact, their over-use may result in a condition known as rebound erythema, which is permanent and in itself is often confused with Rosacea.

Hi CrazyLady!  Your questions are excellent, but not easy to answer in a short response.  This is a very complex issue.  I would like to suggest a wonderful book with a 'nasty' name by Sherry Rogers, M.D.  Dr. Rogers is a leading expert on environmental medicine and the biochemical causes of disease.  The book is called: "Detoxify or Die".  It covers this issue in detail, yet it is easy to read and is packed with the scientific references that support the information as science and not heresy.\n\nThe book is available at Amazon.com or from the publisher (at 1-800-846-6687).  I highly recommend this book if you are serious about your health and detoxification issues.\n\nBest wishes and good luck.

you may be having some sort of allergic reaction or medical condition like rosacea.  You better see a doctor.  In the meantime, you can use a green based powder, (yes green), like one from Physician's Formula, to dust over your face after applying your make up and it will offset the red and make your face look all normal again!

Yes it is biologically related. Pheromones (chemical scents that all of us emit) influence the menstural cycle of women, and are the cause of this phenomenon.\n\nCheck out the link for a more scientific explanation: http://serendip.brynmawr.edu/biology/b103/f00/web2/braha2.html\n\nThis phenomenon is widespread in nature. Plants use a similar mechanism to thwart pests. I.e. when a plant gets attacked by pests, it releases a pheromone which alerts other plants -- which enables them to build up defenses to combat the pest. http://www.jhu.edu/~newslett/01-28-99/Science/3.html

Hi Hermes\n\nHere is the answer.\n\nHydration for Resplendent Skin \nNicholas V. Perricone MD - "We must drink eight to 10 glasses of pure water a day. Diet sodas and coffee don’t count, though I’m allowing tea (green or black) as part of the 8 to 10 daily glasses. When we decrease inflammation in the body, the brain works better, mood is elevated, skin becomes more radiant, dark circles and puffiness under the eyes resolve, skin becomes more toned, and even fine lines can diminish. We must remember that the skin is a reflection of our internal health. Therefore, if our skin improves, all other vital organs also improve. This decreases our risk of every disease from which we suffer." Nicholas V. Perricone MD, is the author of  “The Wrinkle Cure.” \n\nBatmanghelidji MD - "Drinking water enables the skin to better shed toxins and thus keeps it cleaner. When the skin is dehydrated it cannot shed toxins from the body and skin rashes or breakouts can occur. Use 1/4 tsp. of sea salt for every quart of water you drink.  Use a good sea salt, one with at least 80 minerals,  liberally with food.  As long as you drink the water, you can use the salt.  Some put it in their  water, some lick it off their hand, some season their foods after cooking. It's up to you. Make sure you take potassium daily (banana, orange juice,etc) "  \n\nBest of health to you\n\nCheers

Ok obviously this is for a class - so why don't you consult your text book.  The answer will be in there.  Think about it logically too - your skin, in an of itself is a natual barrier.  It is made of tightly packed cells that are keratinized to prevent too much water getting in.  Get the drift...??

Besides an absolutely normal pathology, you would expect all body fluids to be more concentrated.  This is because the osmotic difference between the surrounding water, and that in the body would cause wate to LEAVE the body.  This CAN happen via the skin, even thought the skin is fairly (but not entirely) waterproof.\n\nRemember that the process of osmosis causes fluids to follow the solute concentration, so a hypertonic solution such as very salty (sea) water would attract fluid, whereas hypotonic solutions (those devoid of solute) would effectively repel water.\n\nBottom line is water would be attracted out of the body tissues and blood into the surrounding sea water.\n\nNOTE THAT SURFGIRLTOGO's ANSWER ABOVE IS NOT CORRECT.  If the salt was INSIDE the red blood cells, the osmotic pressure differential would cause them to lyse and burst.  But as the salt water is OUTSIDE THE BODY, the water would be attracted OUT of the RBC's (and all other 9 types of cells in the blood) causing them to shrivel instead.
