How might estrogen-based strategies complement or reduce reliance on injectable fillers?
Estrogen based skincare, especially topical estriol like what we use here at Alloy, can absolutely support the same concerns that often lead people to injectable fillers, and in some cases it can help reduce how much filler someone feels they need.
Fillers mainly add volume when skin has thinned or lost elasticity. What estriol does is address the underlying reason that thinning is happening in the first place. As Dr. Ellen Gendler explains, once estrogen drops during perimenopause and menopause, collagen, elastin, and hydration all take a hit. Topical estrogen helps rebuild collagen, improve firmness, and boost hydration in the deeper layers of the skin. When the skin itself becomes thicker, springier, and better hydrated, it naturally looks smoother and less collapsed.
So fillers can still be helpful for things like deep folds or areas where volume loss is more structural, but strengthening the skin with estrogen often means you may not need as much filler, or you can stretch out the time between appointments. Many women like approaching it this way because fillers can only do so much on skin that’s getting thinner every year, while estriol helps improve the skin itself.
If you want to hear Dr. Gendler talk about where topical estrogen fits in a routine, this chapter from our conversation with her is great: Integrating Topical Estrogen into Skincare.
If you’re curious about trying an estriol formula, you can take a look at our prescription M4 Face Cream Rx, which is designed specifically for collagen stimulation and elasticity during perimenopause and menopause: M4 Face Cream Rx.
