I remember the exact moment my skin changed. It wasn't a gradual slide; it felt like a cliff.
I turned 46, and suddenly, the "Holy Grail" moisturizer I'd used for a decade (the expensive one in the blue jar) stopped working. My skin felt like paper-thin, dry, and constantly thirsty. No matter how much I layered on, I looked dull and tired an hour later.
I thought I just needed more moisture. I bought oils, balms, and slugs. Nothing worked.
I finally spoke to a leading esthetician who explained the science that most skincare brands ignore. She told me, "Sarah, your skin isn't dry. It's leaking."
