Estrogen is the primary female sex hormone. Among other roles, it promotes the development and maintenance of female characteristics in the human body. Estrogen is a generic term for estrus-producing compounds; the three most common naturally occurring estrogens are: Estrone (E1), estradiol (E2), and estriol (E3).
Oestrogen is a powerhouse hormone. It stimulates maturation of a girl's body at puberty. It helps keep a woman's bones strong. Another thing oestrogen does is stimulate the formation of skin-smoothing collagen and oils. That's why, as menopause approaches and oestrogen production diminishes, dry, itchy skin becomes very common. That reduction of oestrogen, and the changing ratios of hormones in your body, don't just slow down your body's oil production, they also reduce your body's ability to retain moisture.
