Diane-35 is a medication available in Canada, Europe and Asia that is used for birth control and acne treatment. According to New Health Guide, Diane-35 is used to treat moderate acne in women over the age of 14. It is classified as an oral contraceptive.
A prominent ingredient in Diane-35 is cyproterone acetate, which is an antiandrogen. Antiandrogens block hormones that cause fertilization and decrease ovarian cancer, male-pattern hair growth and acne, according to Reference.com.
Diane-35 has been found to be effective in treating moderate acne with regular dosage, and extended usage treats more severe acne cases. While Diane-35 does heal acne, it may be required that the patient continue using the medication months later to prevent acne from reoccurring, states New Health Guide.
