The ingredient has been used in skincare products for a long time, especially in K-beauty. But Dr. Jart popularized it in the US through its Tiger Grass line, which received glowing reviews for soothing dry, sensitive skin. The Cicapair™ Tiger Grass Sleepair Intensive Mask
($39) is one of the products. However, looking through the ingredient list, we found the Centella extract to be at the very bottom of the ingredient list (indicates very low %), and the main ingredients are actually Glycerin and Niacinamide. This is another classic case when brands put a low concentration of popular ingredients into a product to market it more easily.
