When estrogen declines, your body loses a critical fatty acid called Gamma-Linolenic Acid (GLA).
GLA is what your skin uses to build the barrier structures that seal cells together and regulate inflammation.
Without enough GLA, your skin barrier breaks down from within.
So when the Nighttime Inflammation Surge hits—cortisol drops, pro-inflammatory cytokines surge, body temperature rises—your GLA-depleted skin has ZERO defenses.
Your nerve endings become hyperreactive. Your barrier can't protect you.
And the itch EXPLODES. Same time. Every night.
This is why moisturizer doesn't work—you're sealing the surface when the barrier is broken internally.
This is why antihistamines barely work—the itch is driven by inflammation hitting depleted, defenseless skin.
This is why it's always at night your body's inflammation surge is synchronized to your sleep schedule.
The solution:
You can't change your circadian rhythm. The surge will always happen.
But you can restore your skin's ability to defend itself.
The answer:
Direct GLA supplementation from borage oil.
