Depending on the severity of the rosacea, a session lasts between ten and thirty minutes. The result is usually immediately visible within the next few days, so that one treatment is sufficient in mild cases. In the case of extensive reddening and a large number of small vessels distributed over a large area, the laser obliterates more and more vessels from session to session until the desired result is achieved. Larger capillaries usually degenerate during the first session and disappear after healing.

After the laser treatment, small scabs can form, which heal over the course of a week. In the case of extensive rosacea, facial reddening is visible after the treatment, but usually disappears after a few days.

After the treatment sun protection is essential. Direct sunlight should be avoided on the day of treatment.

During the laser treatment, it is noticeable where on the face the laser is currently being used. Patients describe the feeling as if a firmer pin were touching the skin. A «pricking» can be felt in larger vessels, somewhat more clearly on the nose, for example, than on other parts of the face. As a rule, the treatment can be carried out without pain-relieving drugs. However, in order to make the treatment much more comfortable and to significantly reduce the sensation of pain, cooling the skin with cold air during the treatment is recommended.
