Carol had done everything right.
She wore sunscreen every day, drank her water and followed every rule she'd ever read about aging well.
Then she threw money at it: the $140 hyaluronic acid serum, prescription retinol, a ceramide moisturizer, a peptide night cream and three eye creams she'd given up on.
More than $600 in two years, and her skin was drier than when she started.
Every one of those products was working on the surface of a barrier that had run out of building material.
Her hyaluronic acid was the worst offender. It pulls water into the skin, and a starving barrier is full of gaps, so that water evaporated by lunchtime and took some of her own moisture with it.
So I did what I do for patients whose skin can't tolerate anything else.
I told her to stop everything and use one thing.
Grass-fed beef tallow.
She looked at me like I'd lost my mind. "Beef? On my FACE?"
I opened a jar and held it under her nose. It smelled like warm vanilla buttercream.
"Your barrier is built from fat," I told her. "Menopause took that fat away. This jar is full of the exact fatty acids your skin turns into ceramides, and it has two ingredients, so there's nothing in it to burn you."
One jar cost $44, against $1,200 for the laser, so she took it home.
