Dr. Carrie Jones: perimenopause skin changes, hidden histamine triggers, and the labs worth asking for

In your 40s, skin can suddenly turn red, itchy, flaky, or reactive, sometimes in random places, and most women assume it is just aging or blame their skincare. But the estrogen and progesterone shifts of perimenopause can change how mast cells release histamine at the skin barrier, which means the trigger may be happening inside the body, not inside the bottle.

We dive deeper into this in the Biohacking Beauty Podcast with Dr. Carrie Jones. We also chat about why a retinoid you have used for years can suddenly irritate your skin, why wine hits so differently in your 40s, and the overlooked lab that could explain hair loss and fatigue.
