This is a great artice and thank you very much for posting it. If I could just add that anyone who has had PDT within the last few months needs to be extra ultra careful of the sun after undergoing that treatment. For those who don't know, PDT makes the skin and eyes extremely sensitive to lights and the sun anyway and that will be exacerbated greatly with the summer sun. Sunscreen and lotions will not be effective here for blocking the damage that sun and light will do after having PDT. After my dad had his treatment, he had to cover up completely on leaving the hospital. Wide brimmed hat, gloves, full covering on all skin and he had to get his glasses darkened by his optician as sunglasses were not strong enough. This went on for a few months and I can't stress enough the damage the effects of the sun and light can do for someone who has recently had PDT. Apologies if I sound like I am going over the top here, but I saw how quickly my dads hand would burn standing outside for 10 minutes in virtually no sun when he was doing the paper bag test 8 weeks after having his PDT.
Thanks again Marion!
