Adopt the “glass skin” look K-Beauty style with this ultra-fresh hydrogel mask from COSRX. After cleansing and toning your skin, apply the mask to your face, adjusting it well to the contours. Leave it on for 15–20 minutes to let the PDRN and hyaluronic acid plump and deeply hydrate, then remove it and gently pat the excess serum until absorbed. Ideal 2 to 3 times a week for plump, radiant, and soothed skin, especially during periods of fatigue or before an event.
