Use this MEDIHEAL The EGT Ampoule Mask on clean skin, preferably after your lotion/toner. Apply the sheet to your face, adjusting it well to the contours, then leave it on for 15 to 20 minutes to allow the ampoule to work deeply. Remove the mask and gently pat the remaining essence without rinsing, then follow with your moisturizer. Ideal 2 to 3 times a week for smooth, plump skin with a K-Beauty effect.
