Rosacea is a benign but chronic dermatological condition.  As it often affects the face, it can have annoying psychosocial repercussions. It is characterized by redness mainly on the face, but sometimes also on the neck and upper chest. The origin of rosacea being vascular, therefore the old term “acne rosacea” should be abandoned. Rosacea has nothing to do with acne. The origin of rosacea is the pilosebaceous follicle and not the blood vessels.

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.

An excellent internet site explains it all very clearly


Not all redness on the face is rosacea. An initial diagnosis by a dermatologist is essential before starting any treatment. You must know how to distinguish rosacea from seborrheic dermatitis or chronic lupus erythematosus, whose medical care will of course be completely different.


While drug treatments will help fight inflammation, only lasers are able to reduce redness. Indeed, this one being due to dilated vessels in too great number into the skin, the treatment will consist in eliminating them by specific photocoagulation.

For the basic mechanism of action of lasers, see under:

Depending on the stage of your rosacea, it will take 2 to 6 laser sessions to achieve significant improvement. Unfortunately, lasers have no preventive effect on the fabrication of vessels. Being a chronic condition, it will therefore be necessary to consider a maintenance treatment to sustain the improvement obtained. The frequency of this maintenance will be specified to you during the first consultation. Finally, note that the treatment usually has no effect on the flushing.  

IMPORTANT medical health insurances do not reimburse laser treatments for rosacea.
