# Topical Estriol: Why Continue If Early Changes Are Modest

> Why keep using topical estriol when results are subtle? Learn how gradual skin benefits, collagen support, and safety justify continued use over time.

## What justifies continuing a topical estriol product when early changes are modest?

What justifies sticking with it is that topical estriol tends to work gradually, not overnight. At Alloy, our clinical data on [M4 Face Cream Rx](https://www.myalloy.com/solutions/m4) showed significant improvements after 12 weeks, including better elasticity, hydration, texture, and overall skin health compared with placebo. Separate research cited in our science pages found that after 6 months of topical estrogen use, skin firmness and elasticity improved, and wrinkle depth and pore size went down.

That slower timeline makes sense biologically. Estriol helps restore moisture, support collagen, and improve elasticity in estrogen-deficient skin, and those are changes that build over time. It’s also a less potent estrogen than estradiol, while still being effective topically, so early changes may feel subtle before they become more noticeable.

Another reason people continue is safety. The data we share shows topical facial estriol works locally on the skin and does not meaningfully raise systemic estrogen levels, so for many women it’s reasonable to keep using it while waiting for the cumulative skin benefits to show up.

If you want the deeper research behind that, these are the most useful reads: [The science behind topical estrogen](https://www.myalloy.com/science/skin), [The science behind putting estrogen on your face](https://www.myalloy.com/blog/the-science-behind-putting-estrogen-on-your-face), and the [full M4 clinical study](https://assets.ctfassets.net/md0kv0ejg0xf/4gaULAkbHbgNZtNMOgg1PI/91329de08abacf438fb83d99e756ee99/Alloy_M4_Report_063024.pdf).
