## Is topical estriol absorbed systemically?

Topical estriol, as used in Alloy's M4 skincare products, is not absorbed systemically. Clinical studies and safety data confirm that topical estriol stays on the surface of your skin and does not enter your bloodstream, so it does not raise estrogen levels in the body. This makes it safe for everyday use, even for those who are not candidates for menopausal hormone therapy (MHT).
