Our sleep improvement patch contains cotton. It can promote nasal breathing, reduce oral dryness, and enhance night breathing comfort. It is very simple to use: tear off the tape before going to bed, thoroughly clean and dry the skin around the mouth, stick this product to your mouth, make sure to cover the entire mouth, and remove the video tape after waking up. And it can provide a quieter sleep environment by reducing nighttime snoring, which helps improve the overall quality of rest.
