PCOS Acne: Hormonal Causes and Treatment Options

Why does PCOS cause acne?

PCOS (polycystic ovary syndrome) causes elevated levels of androgens — hormones like testosterone and DHEA-S — in the bloodstream. Androgens stimulate sebaceous (oil) glands in the skin to produce more sebum, which blocks hair follicles and creates the conditions for acne bacteria to thrive.

This is why PCOS-related acne tends to differ from teenage acne in character and location. It is often: - More prominent along the jaw, chin, and lower face - Present as deeper, cystic nodules rather than surface-level whiteheads - Persistent into the 20s, 30s, and beyond - Resistant to topical treatments that work well for regular acne

The 2023 International Evidence-Based Guideline for the Assessment and Management of PCOS recognizes hyperandrogenism as a core feature of the condition and addresses its dermatologic manifestations including acne and excess hair growth 1Ref 1Teede HJ, Tay CT, Laven JJE, Dokras A, et al. (2023).Recommendations From the 2023 International Evidence-based Guideline for the Assessment and Management of Polycystic Ovary Syndrome.Hyperandrogenism as a core PCOS feature; combined oral contraceptives as first-line hormonal therapy; lifestyle management for insulin resistance.

Do topical acne treatments help with PCOS acne?

Topical treatments — retinoids, benzoyl peroxide, topical antibiotics — can reduce surface acne and are a reasonable starting point or adjunct. The American Academy of Dermatology's acne guidelines describe these agents as effective for inflammatory and comedonal acne generally 2Ref 2Reynolds RV, Yeung H, Cheng CE, Cook-Bolden F, Desai SR, Druby K, Freeman EE, Keri JE, Stein Gold LF, Tan JKL, Tollefson MM, Weiss JS, Wu PA, Zaenglein AL, Han JM, Barbieri JS (2024).Guidelines of care for the management of acne vulgaris.Topical retinoids, benzoyl peroxide, and topical antibiotics as standard treatments for inflammatory and comedonal acne.

However, because PCOS acne is fundamentally driven by excess circulating androgens rather than skin bacteria alone, topical treatments typically provide incomplete relief on their own. They are most useful as part of a combination approach that also addresses the hormonal component.

What hormonal treatments work for PCOS acne?

Combined oral contraceptives (COCs) Estrogen-progestin pills suppress ovarian androgen production and increase levels of sex hormone-binding globulin (SHBG), a protein that binds testosterone and reduces its availability to skin cells. Several COC formulations are FDA-approved for acne, and they are also used in PCOS management more broadly. The PCOS international guideline recommends COCs as a first-line hormonal option for women who also need contraception or symptom management 1Ref 1Teede HJ, Tay CT, Laven JJE, Dokras A, et al. (2023).Recommendations From the 2023 International Evidence-based Guideline for the Assessment and Management of Polycystic Ovary Syndrome.Hyperandrogenism as a core PCOS feature; combined oral contraceptives as first-line hormonal therapy; lifestyle management for insulin resistance.

Spironolactone Spironolactone is an aldosterone antagonist that also blocks androgen receptors in skin and reduces androgen levels. It is widely used off-label for hormonal acne in adult women. A 2025 systematic review and meta-analysis of randomized controlled trials found that spironolactone significantly reduced moderate-to-severe acne in adult women compared with placebo 3Ref 3Kow CS, Ramachandram DS, Hasan SS, Thiruchelvam K (2025).Spironolactone for the Treatment of Moderate to Severe Acne in Adult Women: A Systematic Review and Meta-Analysis of Randomised Controlled Trials.Spironolactone significantly reduces moderate-to-severe acne in adult women versus placebo. It is taken orally daily and generally requires three to six months before full effect is apparent.

Spironolactone is not appropriate for use during pregnancy and requires contraception if you are of reproductive age.

Metformin Metformin, an insulin-sensitizing agent, is used in PCOS primarily for metabolic management. Its effects on androgen levels are secondary to improving insulin resistance, which drives androgen overproduction in many women with PCOS. The Endocrine Society's PCOS guideline notes a modest benefit for hyperandrogenism with metformin, though it is not primarily a treatment for acne 4Ref 4Legro RS, Arslanian SA, Ehrmann DA, Hoeger KM, Murad MH, Pasquali R, Welt CK (2013).Diagnosis and treatment of polycystic ovary syndrome: an Endocrine Society clinical practice guideline.Metformin role in PCOS hyperandrogenism management via insulin resistance reduction.

When is isotretinoin (Accutane) considered?

Isotretinoin is a powerful oral retinoid reserved for severe, nodular, or scarring acne that does not respond to other treatments. It works by dramatically reducing sebaceous gland activity — which is why it can help even hormonal acne. However, it requires strict pregnancy prevention (a formal iPLEDGE program in the US), regular monitoring, and management by a dermatologist.

For women with PCOS who have severe cystic acne that has not responded to topical treatments or hormonal therapy, isotretinoin is a legitimate option to discuss with a dermatologist.

Who should treat PCOS acne — and which specialty?

Because PCOS acne has both a hormonal driver and a skin presentation, the ideal approach often involves two clinicians:

• A dermatologist evaluates the acne severity, recommends topical treatments or isotretinoin if needed, and can co-prescribe spironolactone.
• A gynecologist or endocrinologist (or a primary care clinician experienced with PCOS) manages the underlying hormonal condition — including deciding whether COCs, metformin, or other agents are appropriate for your overall PCOS picture.

Gale does not directly provide dermatologic or endocrine specialist care, but a Gale clinician can help you understand your PCOS diagnosis, discuss whether hormonal management is appropriate, and refer you to the right specialist for acne and skin care. A dermatologist is the right primary specialist for your acne management.

Are there lifestyle measures that help?

Addressing insulin resistance through diet and physical activity can lower androgen levels in some women with PCOS, which may indirectly improve acne. The relationship is not as direct as with medication, but sustained lifestyle changes that reduce insulin resistance are a consistent recommendation in PCOS management guidelines 1Ref 1Teede HJ, Tay CT, Laven JJE, Dokras A, et al. (2023).Recommendations From the 2023 International Evidence-based Guideline for the Assessment and Management of Polycystic Ovary Syndrome.Hyperandrogenism as a core PCOS feature; combined oral contraceptives as first-line hormonal therapy; lifestyle management for insulin resistance.

Skin care choices also matter: non-comedogenic (won't block pores) moisturizers and cleansers, gentle exfoliation, and avoiding heavy makeup or pore-clogging products can reduce surface acne flares. However, these steps complement — rather than replace — hormonal treatment when androgens are elevated.
