Acne and rosacea are common chronic inflammatory skin diseases. During pregnancy these skin disorders may become aggravated, in rare cases occurring for the first time. There are no data available for rosacea and little data for acne concerning the course of these skin disorders during pregnancy. Up to 42% of the pregnant women suffer from acne. In 90% of these women the disease existed before pregnancy. In 1/3, however, acne relapsed during pregnancy after a prior disease-free period. In 60% acne deteriorated during pregnancy. Randomized controlled trials for the treatment of acne or rosacea during pregnancy do not exist. In this article the recommendations of current guidelines are modified, so that effective treatments can be recommended without harming the embryo or fetus.
