BEAUTY SECRET: Do you often wake up with creases on your face? The harsh and thick cotton pillowcase might be to blame. However, the silk is soft and smooth, and the friction coefficient to its human body is the lowest in all fibers, only 7.4%. The more hydrated your skin is, the less noticeable fine lines and wrinkles become. | HAIR SALON: Are you tired of waking up in the morning with a frizzy bird's nest on your head? Silk can minimize split ends, frizz, and dryness by containing natural proteins. It can reduce friction by 43% on average. Silk helps to maintain the natural oils in your hair and keep it smooth when you toss and turn at night. Say goodbye to bad hair days and hello to luxurious nights. | TEMPERATURE REGULATOR: Silk naturally regulates heat, which helps you maintain the correct body temperature. It keeps you cool in summer and warm in winter. Silk is a symbol of love and noble, elegance. | NATURALLY MATERIAL: Silk is produced from domesticated silkworms that are bred and raised in captivity. It is a natural material and a skin-friendly choice. The hidden zipper design allows easy fitting and secures the pillow overnight. Easy one-time payment for better skin and sleep. | 100 NIGHT GUARANTEE: We are dedicated to providing a better silk pillowcase to guard your beauty and health when sleep.
