Round Lab Soybean Serum

Round Lab named this serum after yakkong, the small black soybean, and the soy runs all the way through it: black soybean seed extract eighth, then a soy milk ferment, a rye flour ferment and a soybean ferment further down. One reviewer traced the bean itself to the cold highland fields of Jeongseon. But the part of the list that explains how it behaves is the block just under the extract — five ceramides in a row, with phytosphingosine and cholesterol beside them.
