Fight wrinkles with your eyes closed. The iluminage Skin Rejuvenating Pillowcase offers an overnight solution to help maintain your skin's youthful appearance and minimize the visible signs of aging-including fine lines, wrinkles and lack of smoothness. The pillowcase fibers are carefully embedded with Cupron® Copper Oxide technology, derived from a well-known essential mineral. It's clinically proven to reduce the appearance of wrinkles for smoother, younger-looking skin in as little as four weeks with a continuing effect over time. Copper is naturally found in your skin and is known to play an important role in the skin's renewal process. It has been used in makeup, face creams and other skincare products for years, and one of its key properties is its ability to promote the natural growth of proteins in the skin. How to use: Slip over your favorite standard-size or king-size pillow and use nightly. 20" x 26" Standard 249-thread count Non-irritating Technology and color proven to last over 100 washes 100% Cupron copper oxide polyester Machine wash, tumble dry low Imported
