It is required for you to not have a tan prior to VBeam Perfecta treatment. If do have a tan, we ask for you to wait until you return to your normal skin tone to begin treatment. It is recommended to avoid sun exposure before and throughout treatment to maximize results. A sunblock of SPF 30 or higher must be worn daily during this time. Post treatment care guidelines depend on the condition treated and should be discussed with us during your visit. If you have a history of cold sores/ fever blisters (herpes simplex virus), please inform us so we can address that as part of your treatment.
