Rosacea is a chronic skin disorder
characterized by facial redness. The condition sometimes produces pink bumps
called papules or pimples filled with pus – called pustules.
Besides acne, rosacea can be
mistaken for other skin problems such as skin allergy or eczema.
Rosacea has four subtypes:
|
Erythematotelangiectatic rosacea |
The redness tends to flush and the
affected skin is very dry. It can also appear on the ears neck, chest, upper
back, and scalp. |
|
Papulopustular rosacea. |
The redness comes along with red
bumps and pustules. This type can be easily confused with acne. |
|
Phymatous rosacea. |
It is commonly related to an
enlargement of the nose but it can also affect the chin, forehead, cheeks,
eyelids and ears. |
|
Ocular rosacea. |
It is characterized by red, dry,
and irritated eyes
|
Patients may have a combination of
subtypes.
Despite of the uncertainties of the
original cause, there are a number of factors that can trigger the flushing that
characterize rosacea. Most commons are:
-
Exposure to extreme temperatures (heat or cold)
-
Heavy exercise
-
Sunburn
-
Stress
-
Drinks (including alcohol, hot tea and coffee)
-
Foods (specially those rich in histamines like yogurt, bacon etc.)
-
Medications (like topical or nasal steroids and skin-care products)
-
Excess of carbohydrates in the diet.
