Use this 2-in-1 foam in the evening for a fresh, radiant complexion inspired by Korean “glass skin.” On damp skin, lather a small amount and gently cleanse your face, then rinse. To enjoy the vitamin tone-up effect, leave the foam on like a brightening mask for 1 to 2 minutes before rinsing with lukewarm water. Use daily, followed by your skincare routine (toner, serum, cream).
