Our story
The story of two sisters
When Lauren was diagnosed with acute myeloid leukaemia, her sister, Sarah, became her stem cell donor and saved Lauren's life.
As Lauren recovered, Sarah struggled to find natural yet effective products to soothe and revitalise Lauren's cancer ravaged skin.
So she decided to develop her own formulas and, with this act of sisterly love, skincare By Sarah was born.
