Mechanism of action

The cream contains a mixture of estrogen compounds derived from pregnant mare urine, which are absorbed through the vaginal epithelium. These estrogens bind to estrogen receptors in vaginal and vulvar tissues, promoting epithelial proliferation, increasing blood flow, and restoring moisture and elasticity to atrophic tissues. This localized hormone replacement therapy alleviates symptoms of genitourinary syndrome of menopause without requiring systemic absorption.
