Vascular lesions – rosacea / erythroses (laser)

Rosacea face is one of the most frequent reasons for consultation in dermatology. This is a real vascular disease of the skin with a permanent dilation of small blood vessels or capillaries, occurring in predisposed.

There are two forms of rosacea:

  • The real blotches where the vessels have well-individualized for trips to the surface of the skin.
  • erythrose is characterized by diffuse redness. On this erythrosis appears over time visible capillaries in the eye forming small “red hair” or telangiectasia. This is called erythro-rosacea.

At each stage, it may be associated flushing or flushes that can take the appearance of “hot flashes.” Temperature changes, ie the passage of a cold environment to a warm atmosphere, are responsible as well as sun exposure. We also find this phenomenon in case of alcohol consumption (even small amounts) as well as hot drinks or spicy foods. These inconveniences can actually disrupt the social daily life.

The LASER treatment:

essentially using two types of laser:

  • The KTP 532 nm laser and pulsed dye laser
  • in some cases can also be used polychromatic pulsed light (flashlights).
    • The laser will act through an intense light and cause the destruction of dilated capillaries
  • or by a “welding” of vessels (photothermocoagulation)
  • or by bursting them (selective photothermolysis)

This is done while preserving the integrity of the skin, ie without residual scarring. Your dermatologist will advise you between these possibilities, adapting to your particular case.


  • The treatment is done without anesthesia on a previously cleansed skin and perfectly clean.
  • The session lasts about twenty minutes and the laser firing causes a feeling of mini “strokes elastic” accompanied by a slight burning sensation.
  • The immediate aftermath vary depending on the laser type and the settings used:
    • A flush with warm feeling for 2 to 3 days.
    • A slight swelling or edema, especially under the eyes where the skin is thinnest for 48 hours.
    • A slight whitening of the skin with crusts that spontaneously eliminated in 4 to 7 days, while remaining accessible to makeup.
    • Sometimes in cases of severe damage, we must realize purpura (hematoma or “blue”) at the treated area which may last 10 to 15 days but only guarantee in this case a real effectiveness.
  • The results are visible within a period of about 6 to 8 weeks.
  • On average treatment requires 3 to 4 sessions, spaced two months, except in cases of purpura where, as appropriate, only one to two sessions spaced 6 to 12 months are required.
