Stratum C
GCW introduced Stratum C™, a skincare line from London built specifically for menopausal skin, to the United States — and redefined how American women were told to think about aging.
Stratum C™ carries a real scientific claim, and the campaign had to be able to make it. The range uses a blend of peptides that stimulate the skin's own fibroblasts to generate collagen internally. That is a different mechanism from the traditional collagen cream or collagen drink, where the molecule is too large to do more than sit on the surface of the skin or in the gut.
It matters because collagen production falls during menopause, which is when aging accelerates — and it was a conversation the U.S. beauty press was barely having. GCW put the science in front of editors who could evaluate it and gave them a story that was about a life stage rather than a wrinkle.
The line that came back, and became the campaign's headline, was the one that had nothing to do with a jar: the face cream that will keep your skin glowing through menopause.
