Brow and expression lines are a thing of the past. Made of medical grade silicone, SiO patches comfortably hug your skin. The gentle compression prevents muscle movement and flattens skin so it stays smooth. The doctor-recommended patches intensify hydration and support skin’s ability to retain natural moisture, minimizing the appearance of all forehead lines - from horizontal to the 11’s. See results in just a few hours! Continue to use the patches to help prevent existing wrinkles from deepening and new ones from forming.
