Data from vaginal estrogen gives us a pretty helpful window into what happens when estrogen is applied to skin in general. Here at Alloy, we lean on that history a lot, because vaginal estrogen has been studied for decades and we know quite a bit about how it behaves in the body. What those studies tell us is that when estrogen is applied **locally** to thin, estrogen-deprived tissue, it can thicken the skin, boost hydration, and improve elasticity. That is exactly why vaginal estradiol is so good at restoring the vaginal walls in menopause. And importantly, the systemic absorption is very low. In fact, both Dr. Ellen Gendler and Dr. Corinne Menn talk about how, even in breast cancer survivors on aromatase inhibitors, serum levels stay at baseline after the first tiny blip in the early weeks as tissue heals. That low absorption profile is why clinicians like Dr. Gendler felt comfortable experimenting with vaginal estrogen on the face long before we had dedicated formulas. She saw the same kinds of effects on facial skin that she saw in the vagina: plumper, thicker, smoother skin. If you want to hear her describe that in her own words, you might enjoy this short segment from our YouTube webinar: [Vaginal Estrogen Cream for Skin Health](https://www.youtube.com/watch?v=voedsMd4Zsc&t=1714s). [Watch video](https://www.youtube.com/watch?v=voedsMd4Zsc&t=1714s) The big leap from vaginal estrogen to true facial estrogen products is formulation. Vaginal creams are made with estradiol and bases designed for vaginal absorption and shelf stability. They work, but they can feel waxy, sting around the eyes, and they aren’t tailored for cosmetic use. That is exactly why we created our M4 skincare line with estriol instead. Estriol is a weaker estrogen, still very effective for skin, and remains non systemic in clinical testing.

And from there, we were able to design something that works beautifully on the face without the drawbacks of a vaginal formulation.
