Apply this night mask as the last step of your routine, on clean and well-hydrated skin. Place the sheet on your face, adjusting it to the contours, then leave it on while you sleep so the PDRN and collagen can deliver their plumping and soothing effects. In the morning, gently remove the film, massage in any remaining product or rinse lightly, then continue with your morning routine. Use 1 to 2 times a week for rosy, smooth, and bouncy skin, K-Beauty style.
