Almost all patients tolerate this well, and anesthesia is not necessary. If you have been treated with one of the older lasers for vascular lesions the discomfort is much less. After the treatment the skin may have a temporary stinging or burning sensation. This resolves within a few hours. Bruising is very uncommon unlike the older lasers used to treat vascular lesions where bruising could last 7-14 days.
Most patients have no bruising at all.
Immediately after the procedure redness and slight swelling are noticeable. No aesthetic procedure should be viewed as permanent, however, most of the blood vessels treated with the laser are completely eliminated. Some blood vessels may require several treatment sessions to be eliminated. This should be expected for some blood vessels. New vessels can also appear in the treated areas as part of the natural aging process.
