Moisture Serum

A 100 mL serum with a deliberately short ingredient list built around astragalus root extract and olive oil. Pyunkang Yul credits the flavonoids and saponins in astragalus with supporting a weakened barrier, while the oil lays down a film that slows water loss. It is directed at dry or reactive skin, and at skin that manages to be tight and shiny at the same time.
