Apply the AHC Micro Red Collagen Non-Slip Mask to clean, dry skin after your lotion/toner. Carefully place the mask, fitting it well to the contours of your face: its "non-slip" texture adheres perfectly, even if you move. Leave on for 10 to 20 minutes to allow the collagen to penetrate deeply, then remove it and gently pat the remaining essence until fully absorbed. Use 2 to 3 times a week for plump, radiant skin with a K-Beauty glow.
