Frownies Gentle Lifts offer a non-invasive, cruelty-free, and natural method to smooth wrinkles and fine lines around the face and mouth. These self-adhesive patches utilize Frownies' mechanical method to retrain facial muscles, promoting a smooth and flat appearance. Simply remove the backing, smooth out wrinkles with your fingers, and apply the patch over the affected skin for at least 3 hours, or preferably overnight. They are ideal for targeting fine wrinkles around the mouth caused by aging, smoking, or facial expressions, and can also be used on other facial areas. Caution: Do not apply under eyes or on hair, as body hair may fall out upon removal.
