Some people with sensitive and reactive skin types have redness and small, visible vessels on their face. These signs often appear temporarily, but they can become progressively worse and eventually permanent.

What causes visible redness?

Redness or small visible vessels are skin symptoms caused by an abnormality in the face’s venous system, which is not working normally. Redness, with or without heating, is temporary or long-lasting. Certain factors aggravate the condition:
. Experiencing drastic temperature variations (hot-cold);
. Consuming hot and spicy food, alcohol, etc.;
 
Rosacea and couperose, which is a form of rosacea, most often cause redness and visible vessels to appear on the face. But these aren’t the only causes. Certain dermatological diseases that cause dilated blood vessels stimulate couperose and flushing can correspond to underlying diseases that must be explored. In addition, certain medications can cause vascular dilations to appear on the face or increase those already present. A dermatological consultation is therefore warranted if there are doubts.

What are the symptoms of couperose?

Couperosis is a dilation of small superficial skin vessels in the superficial dermis. The medical term corresponding to this vascular dilation is telangiectasias.
The network of superficial vessels forms a "capillary system" made of reddish linear lines on the face. Some of this network’s parameters may vary, depending on the person and his/her skin type, the age of the process, and the internal or external temperature or changes in temperature. The vessels are more or less wide and their colour ranges from bright red to purple or even bluish. The topography varies but is usually relatively symmetrical. Sometimes only the nostrils are affected, but the cheekbones or the cheeks, more generally, are the most common area affected. However, the whole face may be affected.
When the tree branches in telangiectasias are difficult to see with the naked eye and redness dominates, this is called erythrosis. Logically then, the general term describing the condition mid-way between the two variants is erythrocouperosis.
A spider angioma may be observed with couperose. This is a star-shaped vascular tree containing a more or less raised central red spot.
In most cases, couperose is not related to any underlying disease; it appears slowly and progressively. It is a form of rosacea. Flushes may occur before couperose appears. The other signs of rosacea are erythrosis and possibly red papules (small spots) or pustules. Alcohol consumption does not cause couperose or rosacea.

What causes couperose?

The exterior weather conditions play a role, since exposure to bad weather, the sun and outside temperature variations experienced when working or pursuing a hobby can cause it to appear. Alcohol consumption does not cause rosacea or couperose.

Who is affected by couperose?

People with fair, thin skin are more often affected. 

What are the symptoms of rosacea?

Rosacea is a common dermatological condition that only affects the face, particularly the nose, cheeks, forehead and chin. Much rarer, the eyes may be affected (ocular rosacea). Rosacea is not acne, and the term “acne rosacea” which is sometimes used, is being phased out. This visible skin condition is often psychologically challenging because it causes disfiguration and is frequently mistaken for a sign of chronic alcoholism.
Three different forms, three symptom types
 
. The vascular form: erythrosis and couperose
It appears as redness on the face, with or without couperose (small dilated blood vessels on the cheeks and nose, called telangiectasias). This redness may sporadically be accompanied by vasomotor flushes, i.e. sensations of hot flushes on the face that quickly dissipates.
 
. The papulopustular form
Erythrosis is combined with flare-ups of pimples that resemble acne (red spots and small pustules, but no comedones), still found exclusively on the face.
 
. The hypertrophic form
This form characterised by a large, bumpy nose is much rarer and almost exclusively affects men. It is called rhinophyma and is not related to alcohol consumption, unlike what many people think. All of these symptoms often cause significant everyday discomfort and impaired quality of life.

 

What causes rosacea?

Genetic factors: women with fair skin from northern European regions are particularly affected; External environmental factors: exposure to UV rays, temperature changes (certain occupations are more exposed) and stimulant use (alcohol, spices) are dominant in the onset of rosacea; Abnormal facial vein function seems to be the main cause of flushing; A small parasite, Demodex folliculorum, typically found in the skin, appears to play a significant role. Here it causes an inflammatory reaction.

Who is affected by rosacea?

Rosacea is three times more common in women than in men, and people with fair skin are the most affected.
Symptoms often appear around the age of 30, but it has a peak age of around 50.
A frequent characteristic of rosacea is that it occurs as sensitive skin.
