Spearmint tea does not have proven benefit for acne. Current human evidence shows small shifts in androgen hormones in women with hirsutism, not clearer skin.
Here spearmint tea means a daily infusion from Mentha spicata leaves, discussed online for hormonal acne. Hormonal acne means breakouts linked to androgen activity around sebum and pores. This guide explains what researchers tested, why readers link it to acne, and what to do next.

What did the spearmint studies measure?
In a 30-day trial reported by Phytotherapy Research/Grant, 42 women with PCOS and hirsutism drank two cups daily. Free and total testosterone fell, LH and FSH rose, and subjective hirsutism scores improved the 30-day Grant trial. In a 5-day study reported by Phytotherapy Research/Akdogan and colleagues, 21 hirsute women drank two cups daily during the follicular phase.
Free testosterone fell while LH, FSH, and estradiol rose. In the same 30-day PCOS trial, objective Ferriman-Galwey scores did not change significantly after one month, according to the Unbound Medicine summary. Hormone shifts did not produce measurable hair reduction in that short period.
Why do people connect lower androgens to clearer skin?
Androgens can enlarge sebaceous glands, raise sebum, alter follicular keratinization, and support Cutibacterium acnes growth, according to the U.S. National Library of Medicine/StatPearls review the StatPearls acne pathogenesis review.
That chain makes anti-androgen approaches biologically plausible for hormonal acne. A 2019 review in the Australasian Medical Student Journal found no published studies directly testing spearmint for acne the student acne-tea review. Acne benefit is therefore inferred from hirsutism and hormone data, not proven in acne patients.
Where does the case for acne fall short?
The trials were small and brief, with 21 and 42 participants over 5 and 30 days. Participants had hirsutism or PCOS, not general acne.
The American Academy of Dermatology's 2024 acne guidelines conditionally recommend combined oral contraceptives, spironolactone, and topical clascoterone, as reported by MDedge MDedge reporting on the AAD guidelines. Spearmint tea is not listed as an evidence-based treatment.
What are safer next steps?
Moderate tea intake is usually well tolerated, and Medical News Today cites a 2017 study with no adverse effects at spearmint extract up to 900 mg daily. People who are pregnant, breastfeeding, have liver or kidney disease, or take prescriptions should consult a clinician first, according to WebMD and Medical News Today.
Bring a clear plan to that visit: Track breakouts, cycle pattern, dose, and side effects for 8 to 12 weeks if a clinician agrees to a trial. Seek dermatology care promptly for painful nodules, scarring, or lack of improvement.
- ask whether hormonal treatment fits your acne pattern and history
- review pregnancy, breastfeeding, liver, kidney, and medication issues
- discuss proven options before adding tea as an experiment
