Apply these patches to clean, dry skin, directly on areas marked by wrinkles (forehead, eye contour, nasolabial folds…). Leave on for 20 to 30 minutes to allow the collagen to fully absorb, then gently remove without rinsing. Use them 2 to 3 times a week, preferably in the evening, before your night cream, for a smoothing and plumping effect inspired by K-beauty.
