Effect of cyproterone acetate on skin surface lipids.

Skin surface lipids in female patients with acne were examined before and after treatment with the oral contraceptive SH 209 AB (2 mg cyproterone acetate and 0.05 mg ethinyl estradiol) by direct extraction with petrol ether and photometrical determination. A significant reduction in the skin surface lipids was seen, together with a remarkable alleviation of the disease.
