Do I have to use progesterone if I use estrogen products?Updated 9 days ago

Yes — we always recommend using progesterone alongside any estrogen-based product.

Even facial or topical estrogen creams, when used regularly, can raise systemic estrogen levels. While the absorption may be lower, progesterone is still important to help maintain balance and safety.

Progesterone protects the uterine lining from estrogen’s growth-stimulating effects and keeps your hormones working in harmony. And even if you don’t have a uterus, progesterone is still incredibly valuable — it’s protective for the breasts, brain, and bones, and supports calm, sleep, and overall wellbeing.
