Women Report Whole Body Symptom Relief

Tired of stacking pills, patches, and creams?
Most women are told to piece together their hormone care: a patch here, a pill there, a cream to top it off.
Oestra™ replaces the patchwork.
It uses vaginal delivery to bypass the liver, reduce side effects, and give you steady hormone levels for real symptom relief and uterine protection.
This isn’t about adding more hormones.
It’s about smarter delivery, so your body can finally use what it needs.

Science-Backed Improvements in 4 to 8 weeks
98% Improved Vaginal Dryness
Oestra™ delivers bioidentical estradiol and progesterone directly through the vaginal mucosa — a route clinically shown to restore moisture, elasticity, and pH balance. Unlike oral or topical HRT, vaginal delivery offers localized and systemic relief where it’s needed most.
98% Report Better Bleeding Patterns
By optimizing the progesterone-to-estrogen ratio, Oestra™ regulates the endometrial lining, resulting in lighter, shorter, and more predictable cycles. Its vaginal formulation delivers hormones consistently to stabilize fluctuations that often drive heavy or irregular bleeding.
80% Deeper Sleep
Progesterone in Oestra™ supports the brain’s GABA receptors, promoting relaxation and deeper, uninterrupted sleep. Its vaginal delivery offers sustained overnight levels, helping to improve restfulness within the first few weeks.
78% Elevated Moods
Oestra™ balances estrogen and progesterone — two neuroactive hormones that regulate serotonin, dopamine, and cortisol. This improves emotional resilience and reduces hormonal anxiety, irritability, and low mood.
75% Clearer Skin & Better Hair
Oestra™ raises progesterone, which helps block DHT — a primary hormone driving adult acne, facial hair, and scalp thinning. It also improves collagen production, hydration, and elasticity, supporting visibly healthier skin and hair.
80% Improved Energy
Oestra™ replenishes the hormones that power mitochondrial health, thyroid function, and glucose metabolism. This helps reduce hormone-related fatigue and supports more stable, sustained energy throughout the day.
76% Increased Sex Drive & Arousal
Oestra™ allows your body to convert progesterone into testosterone — the hormone behind libido and arousal. With systemic hormone balance and improved vaginal tissue health, sexual desire often returns within weeks.

Oestra™ is 100% bioidentical and plant-based—meaning it’s chemically identical to the hormones your body used to make.
How do you use Oestra™?
Apply a pearl-sized amount of the cream vaginally once a day. It absorbs quickly and gets to work fast—no pills, patches, or injections.

Vaginal = Local Only?
That’s a Myth.
It absorbs into your whole body.
Vaginal hormone therapy bypasses the liver and delivers hormones systemically—not just locally.
- Markedly enhances systemic bioavailability by avoiding first-pass hepatic metabolism
- Near-complete absorption of estradiol and progesterone
- Far exceeds oral (10–20%) and topical (3–20%) absorption rates
- Results in more consistent serum hormone levels and better symptom control
It’s clinically more effective.
Vaginal delivery ensures stable, targeted hormone levels—leading to better outcomes.
- Delivers a more stable hormone profile than oral or topical routes
- Reduces hormonal fluctuations that trigger side effects
- Improves patient ease of use with direct application
- Recognized for superior symptom relief across energy, mood, libido, and sleep
It’s one of the safest routes available.
Vaginal hormone therapy avoids systemic risks by staying out of the liver.
- Doesn’t increase clotting factors or stroke risk
- Doesn’t elevate estrone levels
- Bypasses hepatic metabolism entirely
- Backed by over 50 clinical trials showing controlled, safe absorption through the vaginal mucosa
It protects your uterine lining.
Vaginal progesterone delivers local endometrial protection without unnecessary systemic exposure.
- Uses the “first uterine pass effect” to concentrate progesterone at the endometrium
- Enhances protection when paired with estradiol therapy
- Avoids the reduced bioavailability and side effects of oral progesterone
- Provides a more predictable progestogenic effect with minimal systemic impact
