Welcome to the Buttercup Collection, where golden dreams meet beauty sleep. Your Buttercup frilly pillowcase is crafted from the softest satin with a delicate pinstripe in our signature Buttercup yellow, finished with frill edging for a touch of charm. Infused with natural silver ions, it works while you sleep to help reduce acne and skin breakouts by eliminating 99.8% of bacteria. The smooth, less-absorbent satin helps retain your skin’s moisture and your hair’s natural oils — so you wake up glowing, with fewer tangles and frizz.
