Since 2011, the Lilou brand began a worldwide collaboration with the DKMS Foundation.
The goal was to fund the research of potential donors.
A Puzzle pendant was created, the proceeds from the sale of which were donated to cover the cost of the research. Thanks to this campaign, nearly one million PLN was donated and the genetic material compatibility of almost five hundred people was tested.
As a result of the Donor Day event conducted in all Lilou boutiques across Poland, an actual bone marrow donor was found in Silesia for one of the patients. The recipient was a 5-year-old girl.
