|Experimental: Azelaic Acid Iontophoresis||
iontophoresis with 15% azelaic acid gel twice weekly
|Active Comparator: Azelaic acid topical||
Other: Azelaic acid cream
topical treatment with 20% azelaic acid cream twice daily
Patients will be randomized and allocated in concealed manner to one of the two treatment arms: AAI or topical azelaic acid cream.
Azelaic acid iontophoresis treatment schedule:
Patients randomized to the AAI group will receive iontophoresis with 15% azelaic acid twice weekly over a period of 12 weeks.
Azelaic acid topical treatment schedule:
Patients randomized to the topical treatment group will receive topical treatment with 20% azelaic acid cream twice daily over a period of 12 weeks.
Besides emollients no additional specific treatments will be allowed during the study.
The use of broad spectrum (UVA+UVB) sunscreen is recommended over the entire study period (9 month).
After completion of the active study period (3 month in both treatment groups), maintenance and efficacy of both treatment schedules will be followed up quarterly over 6 month
