What is the active ingredient and concentration in Alloy’s prescription M4 cream?

Here at Alloy, our prescription M4 Face Cream Rx uses estriol as the active ingredient, and the concentration is 0.3 percent estriol.

That exact percentage is mentioned in our video content, and if you want to hear it directly, you can watch this chapter about the cream here: About Alloy M4 Cream.

If you ever want to dig a little deeper into the ingredients or the clinical results, the full product details are on our site too: M4 Face Cream Rx.
