The video features a woman who is demonstrating how to apply a sheet mask. She starts by holding the mask up to the camera, showing the front and back of the mask. Then, she applies the mask to her face, making sure to cover all areas. She adjusts the mask to fit snugly on her face and smooths it out with her hands. The woman then shows the mask after it has been applied, indicating that it is now ready to be left on for the recommended amount of time.
