The first ZENKAI Women patients.

We ran a closed beta before launching publicly. Below: feedback from the first patients and the clinical evidence backing the hormone therapy protocol.

★★★★★
Beta Program

"At 42, every doctor was telling me it was stress. The ZENKAI gynecologist ran the full hormone panel in the first consultation and identified perimenopause. The listening was different — real time to understand the picture."

★★★★★
Beta Program

"Skincare formula prescribed by the dermatologist, with tretinoin and azelaic acid tuned to my skin. Delivered to my door, no re-booking a consultation every refill. The whole process is simple."

📊
Clinical Evidence

"Menopausal hormone therapy reduces vasomotor symptoms in 70–80% of women within 12 weeks and offers quality-of-life, sleep, and bone-health benefits when prescribed by a specialist physician."

Beta program testimonials from the pre-launch phase. Individual results may vary. Hormone therapy, tretinoin and minoxidil must be used under medical supervision.

Women's health, answered.

Is hormone therapy safe?
For most women, yes. The risks associated with HRT have been substantially revised in recent years — for healthy women under 60 with symptoms, the benefits outweigh the risks. Your doctor will evaluate your individual history before prescribing.
Is tretinoin appropriate for every skin type?
Tretinoin works for most skin types, but the concentration and how it's used need to be individualized. More sensitive skin can start at lower concentrations and ramp up gradually. Your ZENKAI dermatologist will adjust the formula to your specific skin.
Do I need lab work to start hormone therapy?
Yes. Your doctor will request a hormone panel (FSH, LH, estradiol, progesterone) and a recent mammogram (if age-appropriate) before prescribing HRT. You can let us know during the questionnaire if you already have recent results.

Your health deserves to be taken seriously.
