Serum 1 is from the Sjal range.

Created by mother and daughter, Karen and Kristin Petrovich, Sjal is a range that aims to simplify the skincare process. Rather than suggesting its users try multiple products, sjal combines science and holisitics to create an all-in-one treatment line. Karen and Kristin worked with a variety of specialists during the creation of the range, including a nutritionist, a chemist and a biologist. The result is a collection of products that are perfect to nourish, treat and repair skin.
