Rosacea is a chronic condition that concerns the central area, the convex regions of the face, characterized by transient or permanent redness, visible blood vessels, inflammatory lesions, sometimes thickening of certain portions of the face (nose, chin). What are the symptoms of rosacea Diagnosis of rosacea Treatment for rosacea Evolution, complications, prognosis up Risks and causes for rosacea Not very well known. A number of factors are involved: genetic, environmental, vascular component, inflammatory, microbial. Genetic factors. Rosacea is more common in people with lighter skin. In addition, there is a predisposition for everyone to react to certain trigger factors.

Environmental factors. Exposure to ultraviolet has an impact on both skin and dermis structures. The most affected are the convex areas of the face where ultraviolet have the greatest impact. However, most patients do not accuse the effects of rosacea after exposure to sunlight. Spicy foods, alcohol, hot drinks contribute to the appearance of rose.

Also, drugs such as cortisone, vitamin B12 or B6 may be involved in the appearance of rosacea. Inflammation plays a special role, inflammatory infiltrates found around hair follicles or hair follicles. The inflammatory response that occurs in the skin is supported by the presence of many peptides and cells involved in inflammation, responsiveness and dilation of blood vessels. Microbial Factors. Demodex (a parasite that lives near the hairline) would stimulate the local inflammatory response.

The data are not very conclusive, this parasite being equally present in healthy people without rosacea. It has been thought that the Helicobacter pylori bacterium was a triggering cofactor for rosacea, but this hypothesis is no longer supported. What are the symptoms of rosacea In general, all rosacea patients have a history of reddening of the face for many years, redness precipitated by exposure to various factors: alcohol, hot drinks etc. Several types of rosacea are described depending on the skin manifestations. Rozaceea eritematotelangiectazica.

It is characterized by the episodic and then permanent skin reddening in the central areas of the face. Blood vessels become visible. The area around the eyes remains mostly unaffected. The skin is harsh, with sputum, dehydrated (water loss is accentuated by dilated blood vessels). The discomfort experienced in the application of care products, makeup is among the first signs of rosacea.

Papulo-pussy rosacea. On the red background of the skin appear pimples, similar to acne. However, the black and white points are missing (comedones open and closed). Rosacea is characterized by the appearance of thickened and red areas of skin, which deforms the face relief, bulging hair, arranged at the level of the nose and chin tip. This type of rosacea is less common.

Eye rosacea may occur before or along with skin manifestations; . top Diagnosis of rosacea No laboratory analysis required. Rarely, a biopsy can be taken to rule out other similar conditions. top Treatment for rosacea The first thing to do in skin care with rosacea or prone to this condition is to avoid trigger factors. Avoid anything triggering redness.

Avoid greasy products, opt for water based products. Do not apply creams with cortisone, though seemingly soothing the rosacea. It's just an appearance, the reality is that they are directly guilty of triggering / worsening. Protect yourself from the sun. Do not expose your skin to high temperature variations, limit alcohol consumption or too spicy foods.

An ice cube held in the mouth between the masses and the mucosa of the cheek soothes the face's redness. Local treatment with azelaic acid-based creams, ivermectin, metronidazole, fusidic acid, tretinoin, tacrolimus is especially recommended for papulo-pustular rosacea. Oximetazoline or brimonidine can temporarily soothe the face's redness. For systemic treatment, long-term cure of antibiotics (doxycycline, tetracycline, erythromycin) or isotretinoin. Laser therapy can improve the red look of the face, destroy the visible blood vessels and can control changes in the face of rosacea.

top Evolution, complications, prognosis Rosacea is a chronic condition that progresses the stage with the stage. If appropriate treatment is taken, the evolution of rosacea can be stopped. Eliminating trigger factors is essential, and sun protection mandatory. Rosacea rarely can have a severe evolution. It is the known form of rosacea fulmimans characterized by severe, acute inflammatory phenomena (heat, intense redness, swelling of the affected area).

Root injuries do not usually leave scars. .
