There is no really effective treatment for rosacea. Good hygiene and the elimination of aggravating factors are advised. In some cases, however, the doctor may prescribe a laser session (15% results). Or sometimes a medicine against low blood pressure, to reduce the redness of the face (flush).
As a first-line treatment with antibiotic cream (with metronidazole), with or without the same systemic treatment (tablet), may be given. Depending on the severity of the symptoms (very numerous or recurring pimples), another antibiotic (doxycycline) may be prescribed (in the summer, remember to protect yourself from the sun because it is photo-sensitizing).
If at the end of the three months of treatment, it has taken effect, only local treatment (with metronidazole) will be continued in order to prevent recurrence.
In the most resistant forms, the doctor prescribes metronidazole by the general route. The treatment can even be extended for six months to a year.
In the case of steroidal rosacea (a disease that appears after prolonged local treatment with cortisone), corticosteroids are contraindicated; even if they lead initially to a very good result, there is subsequently a rebound of inflammatory flares corresponding to steroidal rosacea which will irremediably cause an escalation in the increase of the doses, the aggravation of the disease and the appearance of corticodependence difficult to control later.
Laser treatment is a treatment of choice at the erythro-couperose stage to eliminate small, apparent vessels. It also reduces the diffuse redness of the face. One to several sessions are required depending on the extent of symptoms, spaced a few weeks each. But the laser does not treat the disease. It will be necessary to envisage other sessions later if other vessels reappear. The rates vary according to the place: about 100 euros the session in the hospital. On average 150 euros in a city office. In both cases, these sessions are not reimbursed.
