Accepts healthy volunteers


We previously showed that twice daily intake of a combination of 100 mg lactoferrin, 11 IU vitamin E, and 5 mg zinc significantly reduced both inflammatory and non-inflammatory acne lesions compared to placebo control. In that study, females showed an overall better response compared to males in terms of total lesions. We speculated that the gender effect may be due to mitigation of the pre- menstrual flare-ups women have that lead to recurring acne, making them have a better response. The objectives of this study are: 1.) to characterize the efficacy and safety of 100 mg lactoferrin + 11 IU vitamin E + 5 mg zinc in the adult female population who suffer from hormonal acne, 2.) to determine whether the anti-acne effect is maintained after treatment stops.
