Estriol (E3)

Estrogen, the queen of the female sex hormones, appears in three different forms in the body. While estriol is involved in the balance of estrogen throughout a woman’s lifetime, it primarily steps up during pregnancy when it is produced by the placenta and is crucial to keeping both mom and baby healthy. Topical forms of estriol have been shown to be effective treatments for skin aging and boosting collagen production.
