Frownies Facial Patches work by training the skin and muscles to return to a natural, relaxed state in order to diminish the appearance of deep wrinkles and expression lines. Made with natural, skin-friendly materials, Frownies are comfortable to wear and perfect for use while you sleep, allowing you to wake up to a more youthful-looking complexion. Expression lines and deep wrinkles are caused by repetitive facial expressions such as frowning, smiling, squinting and furrowing your brow. With each facial expression, damage is caused to the tissue that supports the epidermis. To aggravate lines, collagen and elastin production slows as you age, allowing your facial muscles to push skin into a wrinkled state with incredible ease. These two factors cause the deep lines and wrinkles that can make us look years older than we are. Frownies Facial Patches correct these lines and wrinkles with a splint-like structure. While the patch pushes the skin and muscles into a more youthful state, the skin cells move to fill in the space that is created. With regular use, the muscles and skin will learn to hold this position, causing the skin to remain smooth and youthful-looking.
