Verified Patient

"I was 42 and every doctor told me it was stress. The ZENKAI doctor identified perimenopause in the very first consultation. Three months later, I'm sleeping well, my energy is back, and I feel like myself again."

"Compounded tretinoin transformed my skin in 3 months. Dark spots and acne I'd had for years are practically gone. The best part? It cost less than a single in-person dermatology appointment."

Verified Patient

"I started oral minoxidil for hair loss. Four months in, my doctor can already see new hairs growing. The follow-up is constant and she fine-tunes everything with real attention and care."

Questions

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.
