    Abstract: The pharmaceutical composition, especially for treating skin with seborrhea, Acne vulgaris and androgonically conditioned alopecia, contains a hormonal agent including the gestogen, dienogest, or a combination of dienogest and an estrogen, as active ingredient. Methods for treatment of this type of skin condition include topical application of the composition including the dienogest which results in an outstanding sebosuppression, a drastic reduction of androstandiol glucuronide and a moderate competitive blockage of androgen receptor sites. Galenic formulations are described which limit and/or prevent the permeation of the active ingredient through the skin.
