[Plasma androgen levels in female acne patients].

In 30 female patients suffering from acne vulgaris and 32 female controls, we determined the plasma levels of androstenedione, testosterone and dihydrotestosterone. The average rates of all three androgens were significantly increased in acne. But only the dihydrotestosterone rate showed a clear separation from the individual values of the two collectives. These findings suggest increased synthesis of dihydrotestosterone within the skin of patients with acne vulgaris.
