When it was first launched in 2015, Keep Cool’s parent company Adaline kept its focus on producing the perfect sheet mask. Since then, Keep Cool has grown rapidly throughout the U.S., Hong Kong, and Malaysia, growing in popularity for its fun, Instagrammable aesthetic. But don’t let the cute packaging throw you off — Keep Cool offers high quality ingredients in its surprisingly sophisticated products. From its addicting sheet masks (they set the bar high!) to its line of complementary bi-phase mists, Keep Cool is a K-beauty brand to keep an eye on.
