Yaz is a combined birth-control pill approved for moderate acne vulgaris in women who also want contraception. Trial evidence shows it cuts lesions more than placebo, but strict eligibility limits and blood-clot risks shape the decision. Moderate acne means red pimples plus clogged pores that often respond to hormone shifts. The sections below explain results, limits, risks, and practical next steps.

How well does it clear acne?
Two six-month trials in over 1,000 women found Yaz reduced total, inflammatory, and noninflammatory lesions more than placebo, according to Bayer's announcement reported by Fierce Biotech. The benefit grew over months, not days. The hormonal therapy review from Skin Therapy Letter reports about 51% fewer inflammatory lesions with Yaz versus 35% with placebo.
Total lesions fell about 46% versus 34%. Clear or almost-clear ratings remained modest. Roughly 15-21% of Yaz users reached that level, compared with 4-9% for placebo.
How does it work on breakouts?
Yaz combines 3 mg drospirenone with 20 mcg ethinyl estradiol in a 24/4 regimen. Ethinyl estradiol is a synthetic estrogen. Drospirenone is a progestin with anti-androgen activity.
The Bayer product monograph explains that higher sex-hormone-binding globulin traps testosterone and lowers free androgen. Drospirenone also blocks dihydrotestosterone effects at the skin. Less androgen stimulation means less sebum, or skin oil. Less oil reduces clogged pores and inflamed pimples.
Who can consider it?
Use is narrow. According to the DailyMed Yaz label from the U.S.
National Library of Medicine, acne use is only for women who also choose Yaz for birth control. It is not an acne-only treatment. Ads that suggested benefit for all acne drew an FDA warning in 2008, according to the Washington State Attorney General's office.
- At least 14 years old and past first period
- Moderate acne vulgaris, not mild or very severe acne alone
- Wanting daily oral contraception
- No medical reason to avoid combined hormones
What are the main risks and next steps?
FDA's April 2012 safety review found drospirenone pills may carry higher venous clot risk than some other birth-control pills. Reporting on the FDA safety message by News-Medical notes some studies found up to three times the risk. Risk rises with smoking, older age, migraine with aura, prior clots, long immobility, and some inherited clotting disorders.
Ask a clinician to review personal and family history before starting or switching pills. Current acne guidance favors combination care. Dermatology Times reporting on the 2024 American Academy of Dermatology guidance says combined birth-control pills plus topical treatment are conditionally recommended, with limited systemic antibiotic use. Bring a list of past acne treatments, cycle patterns, blood pressure, and clot risk factors to that visit.
