Who is not a good candidate for PDT?
If you are pregnant, have been on isotretinoin within 3 months, or have an active cold sore you should not have this procedure. If you are taking aspirin of blood thinners, you may experience bruising that can take up to two weeks to resolve. If you are tanned or have recently been exposed to the sun in the area you are having treated, you may be more susceptible to potential side effects such as blisters or crusts and/or your treatment may need to be reduced in intensity or postponed until the tan fades. In addition, patients with pacemakers or internal defibrillators should not have this procedure.
