Photodynamic Therapy and BBL for precancer lesions and AK?
Doctor Answers 2
I would do PDT and IPL at least 1 week apart, just to ensure that the skin heals properly between treatments. IPL addresses sun damage and sun spots, whereas PDT is preventative for precancerous skin lesions, but also helps improve skin quality and color. Age spots are best addressed with lasers that target pigmentation (none of which you have done), and unlike sun spots, do not respond to IPL treatments (like BBL).
With cold sores, I usually give valacyclovir pills twice a day for 5 days after doing treatment, but many doctors have different ways of preventing sores with treatments, so there is not only 1 answer.
