Ask your dermatologist about PDT (photodynamic therapy)

PDT is usually used together with 5-amino levulinic acid (5-ALA)
or methyl levulinate (MAL), a photosensitizer.

Note that Asian skin tend to be more sensitive to PDT, so IPL by itself
is also a good treatment option, though slightly less effective.

that was related to PDT despite the short MAL incubation. ''
