Immediately after treatment there may be some transient erythema or purpura, in or adjacent to the treated area, which is more common in older patients or those who are taking blood-thinning medications and should resolve within a few days. The redness and vasculature may not immediately disappear and may take up to several months to fully improve and clear. Typically, maintenance sessions will need to be scheduled for continued improvement of flare-ups. It is possible that some vascular lesions may scab so it is important to always keep the area moist as to reduce the risk of scarring
