What traditional brands don't tell you
The harmful effects of processed industrial cosmetics on your skin
Two sisters. One vision.
Authentic skincare.
Cathy is a research scientist in biology and biochemistry. Faced with organic skincare products that she felt were often superficial, she decided to apply her scientific rigor to meet her own high standards. She formulated what she couldn't find. Her sister Christie, a communications expert, believed in her.
Together, in their workshop in the Basque Country, they created Kosmorebi: not a startup, but a sister-run company that manufactures its own skincare products, combining biological expertise, sincerity, performance, and passion.
