Thalia Filling and Firming Collagen Sleep Mask 15ml is formulated with collagen, which enhances skin elasticity and texture, combating the natural decline in collagen production that comes with aging. This mask helps maintain skin moisture by improving water retention and forming a protective barrier on the skin's surface. It promises fresher and plumper skin from the first application. To use, apply to cleansed face before bedtime, avoiding the eye area, and massage in circular motions. There's no need to follow with a night cream. Rinse off in the morning with lukewarm water. Use once or twice a week. Avoid contact with eyes and keep out of reach of children. For external use only.
