Bi-Est Hormone Cream
Estriol and estradiol, thoughtfully paired — the estrogen story worth understanding.
Estrogen is one of the most quietly influential hormones in a woman’s life — woven through skin, bones, brain, mood, temperature and intimate wellness across every decade. Bi-Est is a thoughtful blend of two of the body’s primary estrogens: estriol — the gentler estrogen most abundant during pregnancy — and estradiol, the most active estrogen of a woman’s cycling years.
Our Bi-Est Hormone Cream delivers 5 mg of bioidentical estrogen per pump (4 mg estriol + 1 mg estradiol) in a thoughtfully formulated transdermal cream — built around real bodies, real routines and real life.
Because every woman experiences hormones differently, hormone wellness is best explored as something personal — with bioidentical hormone therapy approached as a one-of-one plan, not a one-size-fits-all product.

One hormone. A lifetime of quiet contributions.
Estrogen touches far more of daily life than most women realize — skin, bones, brain, mood, temperature, intimacy, cardiovascular wellness and the felt experience of aging well.
Skin Hydration
Estrogen is deeply connected to the moisture your skin holds — the felt softness women often notice slipping.
Collagen Support
A hormone woven into the skin's natural collagen story — a big part of how skin looks and feels across the decades.
Healthy Bones
Estrogen plays a foundational role in the long-term wellness of bones — a quiet lifetime partnership.
Brain Health
Connected to focus, mental clarity and the everyday sharpness women count on.
Mood & Balance
Threaded through the emotional weather of daily life — steadiness, softness and the felt sense of yourself.
Temperature Comfort
Involved in the body's natural temperature regulation — often noticed most when it shifts.
Vaginal Tissue Wellness
Supports the everyday comfort and resilience of intimate tissues throughout a woman's life.
Cardiovascular Wellness
A hormone historically studied for its role in the healthy rhythm of a woman's cardiovascular system.
Healthy Aging
Estrogen is one of the most quietly influential hormones across a woman's entire wellness journey.

“Estrogen isn’t just a menopause hormone — it’s a lifetime hormone.”
Estrogen production is steady and predictable through the classic cycling years.
Most women continue producing steady estrogen — the quiet arc has yet to begin.
Perimenopause: ovarian estrogen production begins to fluctuate — sometimes dramatically.
Menopause arrives and natural estrogen production is dramatically reduced.
Your estrogen story is uniquely yours.
Estrogen doesn’t fall on a schedule. Some women notice estrogen-related shifts in their late thirties — new sleep patterns, changing skin, an unfamiliar emotional weather. Others sail through until menopause makes itself known. That’s the entire reason we champion a personalized wellness partnership over a one-size-fits-all product.
Personalized hormone testing transforms guesswork into a plan — and a plan into a rhythm you can trust.
A daily cream that fits the life you already live.
Our Bi-Est cream is a thoughtfully formulated topical designed for real women — quick to apply, easy to integrate into an existing routine and thoughtfully built around the classic Bi-Est 80/20-style balance of estriol and estradiol.

Balance is often a duet — not a solo.
Many women exploring bioidentical hormone wellness pair estrogen with progesterone as part of a personalized plan. Estrogen and progesterone are the natural counterparts of a woman’s hormonal architecture, and thoughtful balance between them is often at the heart of a well-designed routine.
The right approach — whether estrogen alone, estrogen with progesterone or a broader combination — is deeply individual. Clear suggested-use directions and our educational hormone app are how a truly personalized plan becomes a routine you can trust year after year.

Bi-Est is one part of a bigger wellness story.
The women who feel best tend to pair their hormone routine with the small daily habits that quietly compound. Think of these as the foundation your Bi-Est cream rests on.
Same bedtime, same wake time. Sleep is where hormones do their most active work.
Chronic stress is a hormone story of its own. Rest, breath and boundaries belong on your list.
Whole foods, colorful plates, plenty of protein — the foundation your hormones are built on.
Two to three sessions a week is one of the most hormone-supportive habits a woman can build.
Water before caffeine. Small habit, meaningful difference for skin, mood and energy.
Prioritize protein at every meal — muscle wellness and hormone wellness are close cousins.

The women who feel best repeat the small, quiet habits — every day, most days.
