Rosacea is a benign skin condition. It can have an annoying psycho-social impact because it most often affects the face. It is characterized by mainly redness in the face, but sometimes also the neck and décolleté. The origin of rosacea is so vascular, hence the term "acne rosacea" should be abandoned. Indeed, rosacea has nothing with acne. Its origin is the pilosebaceous follicle and the vascular compartment.

Rosacea described usually in four (4) stages

1. Intense transient redness (in English "flushes")
2 Permanent redness forms Erythrosis and couperose
3 'Pimples' inflammatory related to redness
4 Persistent Œdemes and blisters, some areas of the face.

Need to know distinguish rosacea from Seborrheic Dermatitis or chronic lupus erythematosus whose medical support is of course completely different.

Depending on the stage of your rosacea, it will take two (2) to six (6) laser sessions to result in a significant improvement. Unfortunately, lasers have no preventive effect on the manufacture of vessels. Should therefore consider a maintenance to maintain the improvement obtained. The frequency of this interview will be refined during the first consultation. However the treatment had no effect on the phenomenon of flush.

It should be noted that health insurance does not reimburse laser for rosacea treatments.
