The harmful effects of processed industrial cosmetics on your skin
Two sisters. One vision.
Authentic skincare.
Cathy is a researcher in biology and biochemistry. Faced with organic skincare products that she found too often superficial, she decided to put her scientific rigor at the service of her own high standards. She formulated what she couldn't find. Her sister Christie, a communication expert, believed in her.
Together, in their workshop in the Basque Country, they created Kosmorebi: not a startup, but a sister-owned company that manufactures its own skincare products, combining biological expertise, sincerity, performance, and passion.
