Rosacea Symptoms Treatments Preventions

What is Rosacea?

Rosacea (rose-ay-shah) is a common, long-lasting skin condition that causes inflammation and redness of the face. It usually starts with redness on the cheeks and nose, and also can affect the forehead.

Rosacea affects usually fair-skinned adults between ages 30 and 50 who have "peaches and cream" complexions and a history of blushing easily. Women develop rosacea more often than men, but men are more apt to develop lumpy enlarged noses, a condition called rhinophyma. Rosacea often is mistaken for sunburn, and often goes undiagnosed. It is a very treatable condition.

Rosacea Symptoms :-

There are four progressive stages of rosacea.

(1) First Stage :- Flushing and intermittent facial redness Second stage — Persistent redness on the cheeks, nose, chin or forehead.

(2) Third stage :- Small, pus-colored or red bumps, along with tiny blood vessels that appear as red, thin lines called telangiectasias.

(3) Fourth stage :- Bumps and skin thickening of the nose.

Redness :- Facial skin redness looks like a sunburn or blush. This is caused by flushing, which occurs when excess blood rapidly flows through the skin's blood vessels, and the vessels enlarge to handle this flow. Gradually, this redness becomes more noticeable and does not go away. Facial skin also may become very dry.

Pimples :- Small, red and solid or pus-filled pimples may appear on the face. Because these pimples look like teen-age acne, rosacea has often been nicknamed adult acne or acne rosacea. However, rosacea has different causes than acne, and adults with rosacea do not have the whiteheads or blackheads (called comedones) commonly seen in acne.

Red lines (telangiectasias) :- Facial blushing or flushing causes small blood vessels to expand and eventually to show through the skin. These enlarged blood vessels appear as thin red lines (telangiectasias) on the face, especially on the cheeks. At first, telangiectasias may be hidden by the redness of flushing or blushing, but they usually reappear after this redness fades.

Nasal bumps :- Left untreated, rosacea eventually can create small, knobby bumps on the nose, which make the nose appear swollen. This condition is more common among men and is called rhinophyma.

Eye irritation :- Red, dry eyes develop in about half of patients with rosacea. Eye involvement is usually relatively mild. Rarely, severe involvement of the eyes develops. If untreated, it can affect vision.

Rosacea Prevention :-

There is no way to prevent the rosacea, but the symptoms can be reduced by recognizing these common triggers: hot drinks, alcohol, spicy foods, stress, sunlight, extreme heat or cold. These conditions increase blood flow and cause the small blood vessels in the face to widen (dilate). If you have rosacea, try to identify your particular triggers and either modify them or avoid them entirely.

To cleanse and moisturize your face, you should select facial products that do not burn, sting, irritate or cause redness when they are applied. You should wash your face with lukewarm water and a mild soap, using your fingertips to apply the soap gently. You should avoid toners, astringents, scrubs, exfoliating agents and products that contain alcohol or acetone. Hydroxy acids and tretinoin (for example, Retin A) may sensitize the skin to sun, and can worsen rosacea.

Sunscreens and sun blockers should be used regularly and liberally to protect the face. Use sunscreens with SPF factor of 15 or higher. If chemical sunscreens cause stinging, switch to physical sun blocks, which contain titanium or zinc oxide.

Rosacea Treatment :-

Antibiotics :- Topical metronidazole cream or gel (Metro Cream, Metro Gel) is the most frequently prescribed first-line therapy. Other topical antibiotics also may be effective.

Tetracycline and tetracycline derivatives, such as doxycycline, are drugs taken by mouth once or twice per day. They are sold under several brand names. Improvement is usually noticeable within the first two months after beginning treatment.

Azelaic acid (Finacea) :- It is a gel containing dicarboxylic acid, and is used for the inflammatory pimples of mild to moderate rosacea.

Beta-blockers and alpha antagonists :- These medications may reduce flushing through their effect on blood vessels.

Propranolol (Inderal) and nadolol (Corgard) are beta-blockers and clonidine (Catapres) is an alpha antagonist. The use of these drugs for rosacea is off-label, meaning that the FDA has not approved their use for rosacea.

Beta-blockers usually are used to treat high blood pressure and heart disease. Clonidine was developed to treat high blood pressure, but also is used to decrease hot flashes in menopause.

Estrogen :- This female hormone is used when rosacea is aggravated by the hot flashes of menopause. The smallest dose of estrogen that controls menopausal symptoms should be used, then the hormone should be stopped when hot flashes no longer occur.

Laser treatment :- This is used to get rid of dilated blood vessels or to remove excess nose tissue.
