## Why might estriol be chosen over estradiol for facial skincare?

Estriol is often chosen over estradiol for facial skincare because it is a gentler, less potent form of estrogen that works effectively at the skin’s surface without entering the bloodstream. Here at Alloy, we use estriol in our M4 skincare line because:

- Estriol is highly effective at boosting collagen, restoring moisture, and improving elasticity—key factors that decline during perimenopause and menopause.
- Topical estriol acts locally, so it does not impact blood estrogen levels, making it safe for everyday use and suitable even if you are not a candidate for systemic hormone therapy.
- Early studies and clinical trials have shown that estriol is particularly effective for skin health, helping to maintain thickness, hydration, and resilience.
- Estriol is more gentle than estradiol, reducing the risk of unwanted systemic effects while still delivering visible anti-aging benefits.
