Here’s what most women aren’t told:
In perimenopause and menopause, estrogen drops. And that doesn’t just affect mood and temperature regulation.
It can also change your skin’s comfort system in two major ways:
Lower estrogen = skin becomes drier and more reactive
Many women notice dryness everywhere, sensitivity to fabrics, and irritation that “comes out of nowhere.”
Aging slows the enzyme that helps your body produce GLA
Your body normally uses an enzyme (delta-6-desaturase) to convert common healthy fats into Gamma-Linolenic Acid (GLA)—a fatty acid your skin relies on for barrier support and calm signaling.
Over time, that conversion can become less efficient.
And here’s the part that makes this hit so hard:
Skin doesn’t reliably make enough GLA on its own.
So when estrogen drops and conversion slows, your skin can end up under-supplied—right when it needs support the most.
Result: barrier weakness + low-grade inflammation + hypersensitive nerves
That’s why the itch can feel severe even when your skin “doesn’t look that bad.”
