) One day after ALA-PDT treatment. Levulan
ALA was applied to the entire treatment area for 1 hour, unoccluded. IPL treatment with Lumenis One using a 560 nm cutoff fi lter, double pulse of 4 and 4 ms
with a 10 ms delay at a fl uence of 18 J/cm

followed by a 10-minute exposure with the Blu-U. Note the erythema and crusting of all actinically damaged skin.
(
C
) Two days after PDT, treatment, further increase in erythema is seen in areas of actinically damaged skin. (
D
) Three days after PDT treatment, resolution of ery-
thema begins. (
E
) Four days after PDT treatment, further resolution of erythema. (
F
) Seven days after PDT treatment, complete resolution of erythema.
